disclosure of Invention

Problems to be solved by the invention

However, the method of patent document 1 is insufficient in miniaturization, and the obtained composition does not have shape retention. In patent documents 2 and 3, the obtained compositions are not compositions having an appropriate moisture content, and do not have the characteristics of the paste of the present invention. The compositions obtained in patent documents 4 and 5 do not have the maximum particle size before ultrasonic treatment larger than the range specified in the present invention, and do not have the characteristics of the paste of the present invention. Thus, even by such a method, a composition having characteristics of good shape retention and excellent adhesion cannot be realized.

Means for solving the problems

Therefore, the present inventors have found that a paste having industrially preferable characteristics for various uses, such as shape retention and adhesion, can be formed by adjusting the characteristics of the composition, such as the water content, the total oil and fat component ratio, and the mode diameter of the composition, in a composition containing various kinds of fine particles of seeds, grains, beans, vegetables, fruits, algae, and the like, water, and oil and fat at a constant ratio, and have completed the present invention.

Detailed Description

the present invention is not limited to these embodiments, and can be implemented by applying any modification without departing from the gist of the present invention.

The paste containing food microparticles of the present invention is a paste containing 1 or more types of food microparticles selected from seeds, grains, beans, algae, vegetables, and fruits, and an oil or fat, and satisfies all of (1) to (5) and 1 or more of (6-1) to (6-3);

(1) the content of the food particles is 15 to 85 mass%;

(6-3) the advancing contact angle at a measurement temperature of 20 ℃ on a clean glass surface and an inclination angle of 45 ℃ is 50 ℃ or more.

Recently, the range of applications has been significantly expanded due to changes in the physical properties of the raw materials, and thus research on miniaturization techniques has been actively conducted. In the field of food products, research on micronization techniques is actively conducted, but the improvement of adhesion accompanying micronization causes a problem of deterioration in the cleanliness of tableware and production facilities. Further, if the wettability is suppressed in order to improve the cleaning property, the adhesion (ease of adhesion to foods and the like) is lost, and the placement property on foods and the like tends to be deteriorated. That is, there has been no composition having both high adhesion and cleaning properties. Further, if the balance among the total oil content, the moisture content, and the content of the fine food particles in the composition is not appropriate, there is a problem that the shape retention of the composition is lost, and the value as a thixotropic paste is lost.

That is, according to the present invention, a thixotropic paste having the characteristics of a composition containing food fine particles and having appropriate wettability, adhesion and shape retention properties can be provided.

Among the above foods, foods other than microalgae are conveniently used because microalgae having very strong cell walls, such as green algae, are difficult to be micronized.

Among the food materials, seeds, grains, beans, vegetables, fruits, and algae are preferably used, and further, the composition containing a fine food using them as a food has a characteristic of being easily left in facilities, and therefore, the technique of the present invention for improving cleanliness can be suitably used.

These foods may be used in 1 kind or in combination of 2 or more kinds.

The present invention is applicable to a part of a "food product" (for example, "green beans") which is usually supplied to a diet, i.e., a part which is edible (in the case of "green beans", a part of beans taken out from a "pod") and also to a part which is usually not suitable for a diet, i.e., a part which is inedible (in the case of "green beans", the part corresponds to a "pod"). Specifically, as the non-edible part, 1 or more selected from the group consisting of the skin, seed, core, dregs, etc., of the above-mentioned food or processed product thereof, particularly, the part containing a large amount of insoluble dietary fiber can be used. In the present invention, it is preferable to include an edible portion as a food, and further preferable to include both an edible portion and a non-edible portion, and it is most preferable to include both an edible portion and a non-edible portion from the same food because nutrition of the food can be taken without waste. For example, a case where an edible part of corn (a part of "seed") and an inedible part (a part of "core") are used in combination, a case where an edible part of green soy bean (a part of "bean") and an inedible part (a part of "pod") are used in combination, or the like is exemplified as a case where the same food is used. In addition, in the non-edible part, particularly in the case of containing 5% or more of insoluble dietary fiber, the technique of the present invention is more useful in the case of containing 8% or more, more useful in the case of containing 10% or more, and most useful in the case of containing 12% or more, because the ingestion property is remarkably poor. Furthermore, in the non-edible part, the present technology is more useful when the ratio of insoluble dietary fiber/soluble dietary fiber is 10 times or more, because the ingestion property is significantly poor, and is more useful when the non-edible part contains 13 times or more, and is most useful when the non-edible part contains 15 times or more (for example, sweet corn cob, which is a kind of corn, contains 15.1% of insoluble dietary fiber, and the ratio of insoluble dietary fiber/soluble dietary fiber is 21.6 times).

In the present invention, "inedible part" means a part discarded in a normal eating habit, and "edible part" means a part obtained by removing a discarded part from the whole food (more specifically, a purchased form). It is to be understood that the parts and amounts of "inedible parts" in foods and processed foods can be more clearly understood by those skilled in the art who have processed the foods or processed foods by referring to and applying the criteria of "waste rate" and "waste parts" in japanese food standard ingredient table 2015 year edition (seven orders). For example, if "vegetables/green beans/raw", the part, amount of the inedible part can be determined and understood as "waste part: pod (rejection rate: 45%) "(further, edible part is also understood), and if" (cabbage)/cabbage/leaf-forming dish, raw ", the part and amount of the inedible part are determined and understood as" waste part: core (reject rate 15%) "(and thus is also understood for the edible portion).

the technique of the present invention is more preferably used for the parts of the food which are not usually suitable for eating, particularly, the parts of the food having a large amount of insoluble dietary fibers, such as the outer skin, seeds, core, and dregs, because the ingestion property is particularly poor and the parts have not been used for eating in the past.

in particular, the present invention is most suitable for a part (skin, seed, core, dregs, etc.) which is not usually suitable for diet, such as rice, apple, green bean, corn (particularly sweet corn), onion, cabbage, carrot, sweet pepper, beet, broccoli, pumpkin, pea (pea kernel), tomato, citrus (particularly satsuma mandarin, grapefruit), sugarcane, grape, etc., because a part remaining in a rich nutrition is discarded. Further, the present invention can be applied to rice (rice) hulls, corn leaf, pistil and cob, onion skins (protective leaves), pan and head, cabbage cores, spinach roots, cabbage petiole bases, grape skins, seeds, green bean pods, pea pods, pumpkin skins, broccoli stems, beet skins, purple potato skins, sweet pepper seeds and stems, sugarcane bagasse, and carrot skins, for example.

From the viewpoints of stability of oil and fat (oil-separating property) in the composition, formability of a thixotropic paste, and the like, a dried food is preferably used as the food. From the viewpoint of easy development of shape retention and wide application range to various foods and beverages, the quality of the dried food preferably has a water activity value of 0.95 or less, more preferably 0.9 or less, even more preferably 0.8 or less, and even more preferably 0.65 or less. The water activity value of the food material can be measured by a conventional method using a general water activity measuring apparatus.

When a dried food is used as the food, it is preferable to use a method in which a food is dried in advance. The method of drying the food may be any method commonly used for drying food, and examples thereof include drying methods such as sun drying, shade drying, freeze drying, air drying (hot air drying, fluidized bed drying, spray drying, drum drying, low temperature (room temperature) drying, and the like), pressure drying, vacuum drying, microwave drying, oil heat drying, and the like, and since the degree of change in color tone and flavor inherent in the food material is small and odor (burnt odor and the like) other than the food is not easily generated, it is more preferable to use a method using air drying or freeze drying, and it is further most preferable to use low temperature (room temperature) drying.

further, it is more preferable to use a food product subjected to drying treatment in advance and carry out the micronization treatment in the presence of the oil and fat and the water at the ratio specified in the present invention.

the paste of the present invention is a paste containing pulverized particles of a food, that is, a paste containing particles in a state in which a food is pulverized. As described above, the paste of the present invention can obtain characteristics as a thixotropic paste by containing fine particles.

Further, in the present invention, "ultrasonic treatment" means ultrasonic treatment with a frequency of 40kHz at an output of 40W for 3 minutes without specific designation.

From the viewpoint of detergency, stability (oil separation property), ease of ingestion, and the like, the content of the food fine particles in the paste of the present invention is preferably 15 mass% or more and 85 mass% or less, and if less than 15 mass%, the detergency will not be improved, and therefore the content of the food fine particles is preferably 15 mass% or more, and most preferably 20 mass% or more. Further, if the content of the fine food particles exceeds 85 mass%, the quality of food intake becomes difficult, and therefore the content of the fine food particles is preferably 85 mass% or less, preferably 80 mass% or less, preferably 75 mass% or less, more preferably 70 mass% or less, further preferably 60 mass% or less, further preferably 50 mass% or less, and most preferably 40 mass% or less.

In the present invention, the content of the food microparticles in the paste of the present invention is measured with respect to the content of the food microparticles in the paste other than the food or the like having a particle size of more than 2000 μm (2 mm) which is not a measurement target of the laser diffraction particle size distribution measurement and the grain shape image analysis device.

in the case where the paste contains food or the like larger than 2 mm, for example, the paste is passed through a 9-mesh (mesh size 2 mm) screen to remove food or the like larger than 2 mm in the paste, and then the weight of the precipitate portion obtained by sufficiently removing the separated supernatant liquid obtained by centrifugal separation is set as the content of food fine particles. Since a part of the oil and fat and moisture is introduced into the sediment portion, the total amount of the food fine particles represents the total weight of these components and the food fine particles introduced into the sediment portion. In the case where the paste does not pass through the 9-mesh sieve as it is, for example, the paste may be diluted with a solvent such as water or oil, and then the weight of the precipitate portion obtained by sufficiently removing the supernatant obtained by centrifugation from the 9-mesh sieve portion of the diluted liquid uniformly mixed with such a strength as not to affect the size of the food fine particles may be measured. In addition, the remaining portion of the web passing through the 9 mesh may be obtained by sufficiently passing food fine particles having a mesh size smaller than 9 mesh by a spatula or the like after sufficiently leaving the composition still so that the particle size of the composition is not changed.

the conditions for the centrifugal separation may be any conditions as long as the food fine particles are precipitated to the extent that the separation supernatant is removed, and for example, the content of the food fine particles in the paste can be measured by centrifuging the passing portion at 15000rpm for 1 minute and weighing the weight of the precipitated portion from which the separation supernatant is sufficiently removed.

The paste of the present invention contains an oil or fat. Examples of the type of the oil or fat include edible oils and fats, various fatty acids, and foods using these as a raw material, and edible oils and fats are preferably used. In addition, since the paste of the present invention has a total oil content within a specific range and thus has a suitably suppressed wettability, the total oil content of the entire paste is 20 mass% or more and 75 mass% or less. The total oil content of the paste is more preferably 30 mass% or more, still more preferably 40 mass% or more, and most preferably 50 mass% or more. If the total oil content of the paste is less than 20 mass%, the wettability becomes too high, which is not preferable. Further, the total oil component content is more preferably 70% by mass or less, and most preferably 65% by mass or less.

Examples of the edible oil and fat include: sesame oil, rapeseed oil, high oleic rapeseed oil, soybean oil, Palm stearin, Palm olein, Palm kernel oil, Palm fractionated oil (PMF), cottonseed oil, corn oil, sunflower oil, high oleic sunflower oil, safflower oil, olive oil, linseed oil, rice oil, camellia oil, perilla oil, sesame oil, coconut oil, grape seed oil, peanut oil, almond oil, avocado oil, salad oil, rapeseed oil (canola oil), fish oil, beef tallow, lard, chicken oil, or MCT (medium-chain triglyceride), diglyceride, hydrogenated oil, interesterified oil, butter fat, ghee, cocoa butter, and the like, and oils other than cocoa butter are preferably used because the flavor of food can be easily tasted. Further, liquid edible oils and fats such as sesame oil, olive oil, rapeseed oil, soybean oil, milk fat, sunflower seed oil, rice oil, palm liquid oil and the like are more preferable because they have an effect of improving the smooth feeling of the paste, and therefore, they can be used more effectively. The edible oil or fat may be an oil or fat contained in a food such as a pasta, but since the addition of an oil or fat subjected to an extraction purification treatment to a food is excellent in affinity with the food, it is preferable to add an oil or fat subjected to an extraction purification treatment in an amount of preferably 10% by mass or more, more preferably 30% or more, of the total amount of the oil or fat.

Further, since the edible oil or fat has a composition in which the ratio of unsaturated fatty acids (the total ratio of monounsaturated fatty acids and polyunsaturated fatty acids) is greater than the ratio of saturated fatty acids, the edible oil or fat can be efficiently refined, it is preferable that the ratio of unsaturated fatty acids is greater than 2 times the ratio of saturated fatty acids in the whole fat.

Examples of foods using an edible oil or fat as a raw material include: butter, margarine, shortening, whipped cream, and soymilk cream (for example, "jiuliangmeng (こ く り ー む)" (registered trademark) of shin-chang oil co., ltd.), and particularly, a food having liquid physical properties can be conveniently used. Of these, two or more kinds of edible oils and fats, and foods using them as raw materials may be used in combination at an arbitrary ratio.

Since the moisture content of the paste of the present invention is appropriately suppressed by adjusting the total oil content and the moisture content of the entire composition, the moisture content of the entire paste is more than 20 mass% and 80 mass% or less. If the moisture content of the entire paste is 20 mass% or less, the wettability becomes too high, which is not preferable. The moisture may be added in the form of water, or may be contained in the composition in the form of moisture derived from the raw material. The moisture content of the entire paste is more preferably 30 mass% or more, still more preferably 40 mass% or more, and most preferably 45 mass% or more. The moisture content of the entire paste is more preferably 70% by mass or less, and most preferably 60% by mass or less. Further, if the ratio of the moisture content to the total oil component content is 1: 4-4: 1, since wettability is further suppressed, it is preferable, and 1: 3-3: 1, most preferably 1: 2-2: 1.

In the paste of the present invention, if the size reduction is performed until the maximum particle size before the ultrasonic treatment reaches 100 μm or less, the texture of the food is destroyed and an undesirable flavor is easily imparted thereto, and therefore, a method of reducing the size so that the maximum particle size before the ultrasonic treatment is larger than 100 μm is preferable. The maximum particle diameter is preferably measured using a laser diffraction particle size distribution measuring apparatus.

The paste of the present invention is a turbid system and the maximum particle diameter is difficult to be visually recognized, but it is considered that the paste containing particles having a maximum particle diameter of more than 100 μm before the ultrasonic treatment has high hiding properties including particles having a maximum particle diameter of more than 100 μm as visually observed under a microscope.

In the present invention, the maximum particle size is reduced by 10% or more before and after the ultrasonic treatment, and the quality of maintaining stability (oil separation) for a long period of time (for example, 1 month or more at room temperature) is obtained, so that the maximum particle size is preferably reduced by 20% or more, more preferably reduced by 30% or more, more preferably reduced by 40% or more, and most preferably reduced by 45% or more. In addition, from the viewpoint of preventing the pulverization of the texture, the maximum particle size reduction rate by the ultrasonic treatment is preferably 95% or less, and more preferably 90% or less. The "ratio of decrease in the maximum particle diameter before and after the ultrasonic treatment (maximum particle diameter decrease rate)" means a value obtained by subtracting a ratio expressed by "maximum particle diameter after the ultrasonic treatment obtained by the ultrasonic treatment at a frequency of 40kHz and a power of 40W for 3 minutes/maximum particle diameter before the ultrasonic treatment" from 100%. For example, in the case where the maximum particle size before sonication in a certain paste is 200 μm and the maximum particle size after sonication is 150 μm, the ratio of the maximum particle size of the paste decreasing before and after sonication (maximum particle size reduction ratio) is 25%.

In the present invention, the maximum particle diameter can be measured under the same conditions as the mode diameter and the like using the particle diameter of each measurement channel described in table 1 as a standard using a laser diffraction particle size distribution measuring apparatus described below. That is, the frequency of particles having a particle diameter not larger than a particle diameter defined by a channel and larger than a number by one (the lower limit of the measurement particle diameter in the maximum channel of the measurement range) is measured for each channel, and the frequency% of particles in each channel can be determined by using the total frequency of all channels in the measurement range as a denominator. Specifically, as for the results obtained by measuring the particle frequency% in each of the following 132 channels in table 1 described later, the particle diameter of the channel having the largest particle diameter among the channels for which the particle frequency% was confirmed was taken as the maximum particle diameter. That is, in the present invention, a preferable measurement method for measuring a composition containing fine particles of a food product using a laser diffraction particle size distribution measuring apparatus is "to measure the particle size of an object having an upper measurement limit of 2000.00 μm and a lower measurement limit of 0.021 μm by putting the sample into the object using 95% ethanol as a measurement solvent by a laser diffraction particle size distribution measuring apparatus. The sample subjected to the ultrasonic treatment was subjected to ultrasonic treatment at a frequency of 40kHz and a power of 40W for 3 minutes ".

The paste of the present invention exhibits good characteristics by having the maximum particle diameter before the ultrasonic treatment in a specific range, and also having the specific surface area, mode diameter, d50, and the like before and after the ultrasonic treatment in a specific range.

the specific surface area per unit volume in the present invention means a specific surface area per unit volume in the case where the particles are spherical, and is obtained by measuring a sample using a laser diffraction particle size distribution measuring apparatus. The specific surface area per unit volume when the particles are spherical is preferably 1.00 m2/mL or less, more preferably 0.85 m2/mL or less, more preferably 0.75 m2/mL or less, more preferably 0.60 m2/mL or less, and most preferably 0.45 m2/mL or less, from the viewpoint of obtaining a good flavor. From the viewpoint of ensuring good intake properties, the specific surface area per unit volume when the ultrasonic treatment is performed is preferably 0.08m2/mL or more, more preferably 0.09 m2/mL or more, and still more preferably 0.14 m2/mL or more. Further, the specific surface area per unit volume is preferably increased to 1.1 times or more, more preferably 2.0 times or more by the ultrasonic treatment.

the mode diameter is preferably 20 μm or more, more preferably 30 μm or more, further preferably 40 μm or more, and most preferably 50 μm or more before the ultrasonic treatment. Further, it is preferably 400 μm or less.

The mode diameter in the case of ultrasonic treatment is preferably 0.3 μm or more, more preferably 6 μm or more, and still more preferably 15 μm or more. The mode diameter in the case of ultrasonic treatment is preferably 200 μm or less, more preferably 150 μm or less, still more preferably 100 μm or less, and particularly preferably 90 μm or less.

In particular, it is preferable to adjust the mode diameter in the ultrasonic treatment to a certain range because the stability (oil separation property) peculiar to the composition of the present invention is further improved. Further, the mode diameter is preferably 1% or more and 95% or less, more preferably 5% or more and 93% or less by the ultrasonic treatment. By adjusting the mode diameter change rate before and after the ultrasonic treatment to a certain range, stability (oil separation) is improved for a long period of time (for example, 1 month or more at normal temperature), and thus it is preferable. For example, when the mode diameter of the composition before the ultrasonic treatment was 100 μm and the mode diameter of the composition at the time of the ultrasonic treatment was 20 μm, the change rate of the mode diameter before and after the ultrasonic treatment was 20%.

the d50 (median particle diameter) is preferably 20 μm or more, more preferably 25 μm or more, and still more preferably 30 μm or more before the ultrasonic treatment. In addition, d50 before ultrasonic treatment is preferably 400 μm or less, more preferably 500 μm or less. The d50 in the case of ultrasonic treatment is preferably 0.3 μm or more, preferably 1 μm or more, more preferably 5 μm or more, more preferably 8 μm or more, more preferably 10 μm or more, and further preferably 15 μm or more. Further, d50 in the case of ultrasonic treatment is preferably 150 μm or less, more preferably 100 μm or less.

the particle size in the present invention is not particularly limited, and all particles are measured on a volume basis.

The specific surface area (specific surface area per unit volume when the particles are assumed to be spherical) in the present invention is obtained by measuring a sample using a laser diffraction particle size distribution measuring apparatus. The specific surface area per unit volume when the particles are assumed to be spherical is a value based on a measurement mechanism different from a measurement value (specific surface area per unit volume or unit weight obtained by a permeation method, a gas adsorption method, or the like) reflecting a component, a surface structure, or the like of the particles that cannot be measured by the laser diffraction particle size distribution measurement device. When the particles are assumed to be spherical, the specific surface area per unit volume is obtained by 6 × Σ (ai) ÷ Σ (ai ÷ aponifedi) when the surface area per particle is ai and the particle diameter is di.

The mode diameter represents the particle diameter of the channel having the highest particle frequency% with respect to the particle diameter distribution of each channel obtained by measuring the composition using a laser diffraction particle size distribution measuring apparatus. In the case where there are a plurality of channels of the same exact particle frequency%, the particle size of the channel in which the particle size is smallest is employed. If the particle size distribution is a normal distribution, the value is consistent with the median diameter, but if there is a deviation in the particle size distribution, particularly if there are a plurality of peaks in the particle size distribution, the numerical value is greatly different. The measurement of the particle size distribution of the sample by the laser diffraction particle size distribution measuring apparatus can be carried out, for example, by the following method.

For example, a Microtrac MT3300 EXII system available from Microtrac bel corporation may be used as the laser diffraction particle size distribution measuring apparatus. The solvent used in the measurement may be one which does not easily affect the structure of the food particles in the paste. For example, for oleaginous compositions, it is preferred to use 95% ethanol (e.g., JAPAN ALCOHOL trace sells the specific ALCOHOL Traceable 9595 degree 1 grade). Further, as the measurement application software, DMS2(Data Management System version2, MicrotracBEL co., ltd.) was used. During measurement, after a cleaning button of measurement application software is pressed to clean, a Setzero button of the software is pressed to zero, and the sample can be directly input through sample loading until the sample falls into a proper concentration range. For the samples not subjected to the ultrasonic treatment, the concentration range was adjusted to an appropriate concentration range within 2 sample loads after the sample was put in, and the result of laser diffraction was obtained as a measurement value within a measurement time of 10 seconds at a flow rate of 60% immediately after the adjustment, and for the samples subjected to the ultrasonic treatment, ultrasonic treatment was performed at a frequency of 40kHz, a power of 40W and 3 minutes by pressing an ultrasonic treatment button of the same software, 2 times of defoaming treatment was performed, ultrasonic treatment was performed, and then sample loads were performed again, and the result of laser diffraction was rapidly obtained as a measurement value within a measurement time of 10 seconds at a flow rate of 60% after confirming that the concentration is within the appropriate range.

as the measurement conditions, the following distribution was expressed: volume, particle refractive index: 1.60, solvent refractive index: 1.36, upper measurement limit (μm) =2000.00 μm, and lower measurement limit (μm) =0.021 μm.

In the measurement of the particle size distribution of each Channel (CH) in the present invention, the measurement can be performed using the particle size of each measurement channel described in table 1 below as a standard. The particle diameter defined by each channel is also referred to as "the particle diameter of the channel". The frequency of particles having a particle diameter smaller than or equal to the particle diameter specified for each channel and larger than the particle diameter specified for the channel having one larger number (the lower limit of the measurement particle diameter in the maximum channel in the measurement range) is measured for each channel, and the frequency of particles in the channel (also referred to as "∘ particle frequency% in the channel") is determined by using the total frequency of all channels in the measurement range as a denominator. For example, the% frequency of particles in 1 channel means the% frequency of particles having a particle size of 2000.00 μm or less and 1826.00 μm or more.

The paste of the present invention is preferably a thixotropic paste, and the wettability is suppressed to such an extent that the contact angle is in a certain range. Specifically, the contact angle at a measurement temperature of 20 ℃ on the surface of a horizontally-standing clean glass is preferably 40 ° or more and 160 ° or less. When the paste of the present invention is dropped onto a surface of a clean glass (for example, a glass slide "S-1225" manufactured by new sonlanga nit industries, ltd.), which is left standing horizontally, the paste is rounded by its own "surface tension", i.e., the so-called contact angle, which is the angle (degree) formed between the surface of the composition and the surface of the glass (the angle existing inside the composition is adopted) at the position where the free surface of the paste which is left standing (usually, left standing for about 10 seconds after dropping) is in contact with the surface of the glass.

the contact angle in the present invention can be obtained by the following calculation. That is, when about 0.1 mL of paste is smoothly dropped from a height of about 3 cm so that the contact surface with the glass surface becomes a substantially circular shape, the contact angle θ (°) is expressed by the following equation, where the length of the longest straight line that the stationary paste inscribes the substantially circular contact surface with the glass surface after dropping for 10 seconds is 2r (mm), and the distance (height) between the highest portion of the dropped paste and the glass surface is h (mm).

A liquid such as water or oil forms a shield-like droplet on a glass surface, and the contact angle is less than 40 ° (the actual measurement value of distilled water is 2 °). A solid material such as cheese or lard does not form a substantially circular contact surface on a glass surface, and the contact angle thereof is a value larger than 160 ° even if it is assumed to be formed, and therefore, is different from the paste of the present invention.

Since the paste of the present invention has an unfavorable quality because the adhesion effect is reduced when the contact angle is less than 40 °, the contact angle is preferably 40 ° or more, more preferably 50 ° or more, more preferably 60 ° or more, more preferably 70 ° or more, more preferably 80 ° or more, and most preferably 90 ° or more. In addition, the paste of the present invention preferably has a contact angle of 160 ° or less because it is convenient for producing the composition.

Further, the paste of the present invention preferably has a wettability suppressed to such an extent that the slip angle is within a certain range. Specifically, the slip angle at a measurement temperature of 20 ℃ on the clean glass surface is preferably 50 ° or more. The slip angle indicates an angle at which about 0.1 mL of the composition was smoothly dropped from a height of about 3 cm so that the contact surface with the glass surface became substantially circular, and after the composition was left to stand for 10 seconds after dropping, one end of the glass surface was lifted up to start the sliding of the droplet when the droplet was tilted slowly (that is, the position and the shape of the contact surface between the composition and the glass surface started to change).

since the liquid such as water or oil starts to slide down by the slight inclination of the droplet on the glass surface, the sliding angle is less than 50 ° (the actual value of distilled water is 5 °). In addition, in general, a composition having a large contact angle has low affinity for a solid surface and therefore cannot stay on the solid surface, and as a result, the sliding angle becomes small, and the quality such as being difficult to place on food is obtained. According to the technique of the present invention, a paste having a contact angle and a slip angle both in a fixed range, having opposite characteristics (thixotropy such as appropriate wettability, adhesion, shape retention, etc.) which have been difficult to achieve in the past, and as a result, having novel and advantageous characteristics can be provided.

when the slip angle of the paste in the present invention is less than 50 °, the shape retention property is lowered, and therefore, the slip angle is not preferably 50 ° or more, more preferably 60 ° or more, further preferably 70 ° or more, and most preferably 85 ° or more.

further, the paste of the present invention preferably has a wettability suppressed to such an extent that the advancing contact angle falls within a certain range. Specifically, the advancing contact angle at a measurement temperature of 20 ℃ and an inclination angle of 45 ℃ on the clean glass surface is preferably 50 ° or more. The advancing contact angle represents an angle (degree) formed between the surface of the paste and the glass surface (using an angle existing inside the paste) at a position where the free surface of the paste is in contact with the glass surface when about 0.1 mL of the paste is smoothly dropped from a height of about 3 cm so as to form a substantially circular shape with respect to the contact surface on the glass surface and the glass surface is inclined to an angle of 45 degrees after the paste is left to stand after dropping for 10 seconds. Since the advancing contact angle of a paste having a strong solidity property is less than 50 ° at a measurement temperature of 20 ℃ on a clean glass surface and an inclination angle of 45 °, deformability which is a premise of shape retention is insufficient, the advancing contact angle is not preferably 50 ° or more, more preferably 60 ° or more, further preferably 70 ° or more, and most preferably 90 ° or more. Further, the advancing contact angle of the paste having a strong liquid property is preferably 165 ° or less because the shape retention property is insufficient, and the advancing contact angle is not more than 165 °.

As described above, the paste of the present invention exhibits the preferable effects of the present invention by satisfying one or more requirements of the degree of suppressing wettability to a certain range of contact angle, the degree of suppressing wettability to a certain range of sliding angle, or the degree of suppressing wettability to a certain range of advancing contact angle, more preferably 2 or more, and most preferably all 3.

When the ultrasonic treatment is performed on the paste of the present invention, it is preferable that the relational expression "α × 2.6 + β × 0.03" satisfies 2.2 or more, that is, satisfies the following relational expression when the specific surface area per unit volume (m2/mL) after the ultrasonic treatment is α and the contact angle (degree) at a measurement temperature of 20 ℃ on a clean glass surface is β, because the fluidity is appropriately suppressed and the drip easiness when the paste is used for foods and beverages is improved.

α×2.6＋β×0.03≥2.2

Further, the relational expression "α × 2.6 + β × 0.03" preferably satisfies 2.4 or more, and most preferably satisfies 3.0 or more.

Further, the viscosity (20 ℃) of a medium containing a food, which is obtained by containing the food in oil or fat or water before the refining treatment, can be adjusted to 20Pa, seeds or less and to 8Pa, seeds or less, whereby the refining treatment efficiency can be further improved, and therefore, the method is useful. Further, the viscosity (20 ℃) of the composition containing fine particles of food is preferably adjusted to 10MPa, seeds or more, and more preferably adjusted to 50MPa, seeds or more.

the paste of the present invention is preferably a thixotropic paste. Here, the "thixotropic paste" in the present invention is a paste-like composition having a certain shape retention property, having a texture that is easily deformed when stress is applied, exhibiting behavior like a weak gel, and having a viscoelastic body having both solid and liquid characteristics. For example, a typical thixotropic paste can be specified by a viscosity measurement (cm) using a Bostwick viscometer (measurement temperature 20 ℃, 10 seconds). For example, since the viscosity of a thixotropic paste having a slightly strong solid property is measured by a Bostwick viscometer (measurement temperature 20 ℃ C., 10 seconds) at a value of less than 0.1cm, the measured viscosity is preferably 0.1cm or more, more preferably 1cm or more. Further, since the thixotropic paste having a slightly strong liquid property has a viscosity measurement value (measurement temperature 20 ℃ C., 10 seconds) of more than 22 cm, the viscosity measurement value is 22 cm or less, and the drip easiness in use for food or drink is improved, and therefore, it is preferably 20 cm or less, more preferably 17 cm or less, and further preferably 15 cm or less.

The paste of the present invention has appropriate wettability, adhesion and shape retention. Although the principle of exhibiting thixotropy is not clear, it is considered whether the reason is: a gel network structure is formed by dispersing food particles of a specific size in the presence of a specific ratio of fat to moisture, exhibiting the same behavior as a weaker gel.

The viscosity measurement of the present invention can be measured using a Bostwick viscometer. Specifically, measurement can be performed using a KO Bostwick viscometer (manufactured by deep-valley iron works, Inc., having a cell length of 28.0cm and a Bostwick viscosity, that is, a flow-down distance in the cell of the sample of at most 28.0 cm). In the measurement, the apparatus was horizontally set by using a level meter, the storage tank was filled with a sample adjusted to 20 ℃ until the full volume after closing the gate, the gate was opened by pressing the trigger, the time was measured, and the flow-down distance of the material in the tank at the time of 10 seconds elapsed was measured, whereby the viscosity measurement value by the Bostwick viscometer was measured.

The paste of the present invention may contain various foods, food additives, and the like, which are generally used for foods, as necessary, within a range satisfying the requirements of the paste. Examples thereof include: soy sauce, miso, alcohols, saccharides (glucose, sucrose, fructose, glucose fructose, fructose glucose solution sugar, etc.), sugar alcohols (xylitol, erythritol, maltitol, etc.), artificial sweeteners (sucralose, aspartame, saccharin, acesulfame K, etc.), minerals (calcium, potassium, sodium, iron, zinc, magnesium, etc., and salts thereof), flavors, pH adjusters (sodium hydroxide, potassium hydroxide, lactic acid, citric acid, tartaric acid, malic acid, acetic acid, etc.), cyclodextrin, antioxidants (vitamin E, vitamin C, tea extract, green coffee bean extract, chlorogenic acid, flavor extract, caffeic acid, rosemary extract, vitamin C palmitate, rutin, quercetin, myrica rubra extract, sesame extract, etc.), and the like. In addition, it is also possible to add: emulsifiers (glycerin fatty acid ester, acetic acid monoglyceride, lactic acid monoglyceride, citric acid monoglyceride, diacetyl tartaric acid monoglyceride, succinic acid monoglyceride, polyglycerol fatty acid ester, polyglycerol condensed linoleate, quillaja extract, soybean saponin, tea seed saponin, sucrose fatty acid ester, and the like), colorants, thickening stabilizers, and in order to improve the natural pursuit in recent years, it is desirable not to add so-called emulsifiers and/or colorants and/or thickening stabilizers (for example, substances described in "food additive material name table for display" in the food additive display pocket book (2011 edition) as "colorants", "thickening stabilizers", and "emulsifiers"), in particular, the addition of no emulsifier is preferable because it gives a quality that the taste of the raw material is easily perceived. Further, it is most desirable that the food additive not contain a quality of a food additive (for example, a material used for food additive use described in "food additive for display material name table" in a food additive display pocket book (2011 edition)). Further, since it is difficult to perceive the sweetness of the raw material itself, it is preferable not to use a purified saccharide other than the raw material (glucose, sucrose, fructose, glucose fructose syrup, fructose glucose syrup, etc.), and it is preferable to use a sweetness derived from a fruit juice or a concentrate thereof (apple juice, grape juice, date juice).

The paste of the present invention can be basically produced by subjecting the food, preferably the dried food, to a pulverization treatment or a pulverization treatment at a certain moisture content and a certain total oil content ratio as required.

The pulverization treatment or micronization method used in the present invention is not particularly limited, and may be any of machines called a mixer, a stirrer, a grinder, a kneader, a pulverizer, a disintegrator, an attritor, and the like, may be any of dry pulverization and wet pulverization, or may be any of high-temperature pulverization, normal-temperature pulverization and low-temperature pulverization. For example, as the dry type micro-pulverizer, a media agitation mill such as a dry bead mill or a ball mill (rolling, vibrating, etc.), a jet mill, a high-speed rotary impact mill (pin mill, etc.), a roll mill, a hammer mill, or the like can be used. For example, as the wet micro-pulverization, a media stirring mill such as a bead mill or a ball mill (rolling mill, vibration mill, planetary mill, etc.), a roll mill, a colloid mill, Starburst, a homogenizer (high pressure homogenizer), or the like can be used. As the paste containing food fine particles of a specific shape in a state of being subjected to wet micro-pulverization treatment, a media agitation mill (ball mill, bead mill) or a homogenizer (particularly, a high-pressure homogenizer) can be preferably used. For example, a homogenizer (particularly a high-pressure homogenizer), a stirred media mill, may be preferably used. When the treatment is carried out using a media-stirring mill, the Bostwick viscosity (measurement temperature 20 ℃) of the contents before the treatment is preferably 10 seconds to 28.0cm or less because the treatment is easy.

In particular, the use of a pulverization method using a wet bead mill or a homogenizer (particularly, a high-pressure homogenizer) is preferable because it provides a paste having a higher quality with stability and less tendency to cause separation of oil and fat when the paste is left to stand than other treatment methods. The principle is not clear, and it is considered that the reason is that the particle state of the food particles is preferably changed by a bead mill treatment, a homogenizer (particularly a high-pressure homogenizer).

The conditions in the wet bead mill treatment are in accordance with the size and properties of the food, and the properties of the target paste containing fine particles of the food, and the size of the beads, the filling ratio, the outlet mesh size, the liquid feeding speed of the raw material slurry, the mill rotational strength, the one-pass method (single pass) or the multiple-pass method (circulation type), and the like may be appropriately selected and adjusted, and the treatment is preferably a single-pass treatment, more preferably a treatment time of 1 minute to 25 minutes, and most preferably 2 minutes to 20 minutes. Further, as the preliminary pretreatment, a material obtained by preliminarily coarsely pulverizing a food product by a jet mill, a pin mill, a stone mill, or the like may be subjected to a micronization treatment, and a powdery food product adjusted to a size of 1000 μm or less and 100 μm or more in median diameter may be subjected to the micronization treatment, and the principle is not clear, but the wettability of the object is more suppressed, and therefore, the preliminary pretreatment is more preferable. In the bead mill treatment, the material of beads is preferably the same as that of the bead mill inner cylinder, and more preferably, the material is zirconia.

In addition, as the homogenizer, any homogenizer can be used as long as it has a particle size reduction and homogenization ability and can perform a certain emulsification dispersion, and for example, HOMO MIXER MARK II (manufactured by PRIMIX corporation) can be used. Further, as the high-pressure homogenizer, any high-pressure homogenizer can be used as long as it is a disperser capable of performing shearing treatment under a pressure condition of 1.00 MPa or more, and for example, a PANDA2K type homogenizer (manufactured by Niro Soavi corporation), CAVITRON (manufactured by EUROTEC corporation), LAB2000 (manufactured by SMT corporation), and the like can be used. The treatment conditions are, for example, preferably a micronization treatment under a pressure adjusted to 0.01 MPa or more, more preferably 0.02 MPa or more, and the micronization treatment can be carried out by performing a high-pressure homogenization treatment under a pressure adjusted to 50MPa or more once or more. In the above-mentioned micronization treatment, it is preferable to micronize the food in a pulverizing solvent. Since the equipment may be damaged if the pressure conditions are severe, the upper limit of the pressure conditions in the refining treatment is preferably 200 MPa or less when the treatment is performed using a high-pressure homogenizer.
