Technical Field

The present invention relates to a method for producing a composite food, and more particularly to a method for producing a composite food which is convenient to produce, can be repeatedly heated without losing its taste, can be preserved for a long period of time, and has a long-lasting freshness-retaining effect.

Background

Conventionally, in order to prevent or slow down the deterioration of food and preserve the nutrition and taste of food, common food preservation methods include drying, freezing, refrigerating, vacuum and adding bacteriostatic agents, while the most common preservation method is a refrigerating method, such as black sugar/caramel pearl balls commonly used in beverages in hand-operated beverage stores, which are frequently required to be preserved in a refrigerating manner during the sale period, and some manufacturers add a proper amount of preservative or artificial starch to the black sugar/caramel pearl balls in order to preserve the quality and elastic taste of the black sugar/caramel pearl balls for a long time, so as to prolong the quality and elastic taste of the black sugar/caramel pearl balls.

The reason why some manufacturers need to add a proper amount of preservative or artificial starch is that the most time consuming stage of the traditional pearl ball is from raw pearl ball to cooked pearl ball, and the traditional pearl ball needs to be cooked for at least 1-2 hours each time every day, and is finished by means of molasses, the cooked pearl ball can be preserved for only 3-4 hours after being honey by cane sugar and the like, and then the pearl ball begins to soften and has a small part of hydrolysis, at the moment, the pearl ball needs to be placed in a cold storage to harden, although the taste of the black sugar/caramel pearl ball taken out from the cold storage and heated is not diluted and is rather sweet, but the taste of the pearl ball is more soft and tender and inelastic, so that manufacturers can add the preservative or artificial starch or add a mass of chemicals which cannot be seen by consumers in order to improve the problems of preservation and taste and avoid the problem that the market pearl ball is not discarded completely, causing the health of the consumer to be eroded as a result of their daily and monthly consumption.

From the above, in order to enable consumers to eat most natural foods, it is necessary to develop a method for producing foods that can preserve foods for a long period of time without adding preservatives, artificial starch, or other harmful substances, and that can maintain the freshness of food materials in foods and can be safely consumed by consumers.

Disclosure of Invention

In view of the above problems, the present invention is to provide a method for producing a compound food with long shelf life, which can produce a compound food with long shelf life and maintain the taste of the food material in the food, wherein the key of the method is to use malt syrup to coat the food material to produce the compound food with long shelf life, the food material can be selected from starch products (e.g., pearl balls), fruits, etc., and the taste of the food material coated with malt syrup is not different from the taste of the food material before coating. The invention also adopts various saccharides to coat the food material to test the storage and taste effects, and finds that the food material coated by the malt extract has longer storage life and maintains the original taste of the food material.

Another objective of the present invention is to provide a composite food produced by the method of the present invention, which can be preserved for a long period of time without adding preservatives or artificial starch or a group of chemicals invisible to consumers, and thus can maintain the safety of consumers. On the other hand, the simpler manufacturing method can also effectively reduce the cost (including manpower and material resources) required by the manufacturer for preserving the food materials.

The invention provides a method for preparing a compound food capable of being preserved for a long time, which comprises the following steps:

sufficiently mixing a proper amount of water with food materials at a high temperature to form a first mixed solution;

stewing the first mixed solution for at least 30 minutes to thoroughly cook the food material;

washing the food material with low temperature ice water;

fully mixing the food material and malt syrup at a reaction temperature lower than 110 ℃ to form a composite food, and reacting for 10 seconds to 15 minutes to enable the malt syrup to coat and infiltrate into the surface of the food material, wherein the malt syrup content is 5 to 30 parts by weight based on 100 parts by weight of the total usage amount of the food material and the malt syrup;

the composite food is stored under refrigeration.

Optionally, the reaction time of the composite food product is 1-10 minutes.

Optionally, the reaction temperature of the composite food product is 100 ℃.

Optionally, the reaction temperature of the composite food is normal temperature.

Optionally, the composite food is filled into a packaging bag and the gas in the packaging bag is pumped out and then sealed.

Optionally, the composite food product has a refrigerated storage life of at least 1 month.

Optionally, the food material is a starchy food or fruit.

In a first aspect of the present invention, there is provided a composite food capable of being stored for a long period of time by a method of manufacturing the composite food according to the present invention, wherein the composite food is produced by coating malt syrup on the surface of a food material and infiltrating the malt syrup into the surface of the food material, so that the composite food can be divided into an inner layer and an outer layer, the inner layer is the food material itself, the outer layer is the malt syrup, and the temperature of the food material when the food material is mixed with the malt syrup needs to be less than 110 ℃ in order to coat the malt syrup on the surface of the food material, because the temperature of the malt syrup when the malt syrup is mixed with the food material is more than 110 ℃ and the malt syrup is hard to be sufficiently mixed with the food material and difficult. In addition, since the hardened malt syrup is hard to permeate into the surface of the food material if the reaction temperature exceeds 110 ℃ in the mixing process, the structure generated by the method of the present invention is hard to be generated. In addition, the reaction time required for mixing the food material and malt syrup is also 10 seconds to 15 minutes, so that the composite food capable of being stored for a long time can be prepared. As can be seen from the foregoing, the method of the present invention can preserve the composite food of the present invention and maintain the freshness and texture of the food material itself without using preservatives or other chemical materials.

In a second aspect of the present invention, there is provided a method for producing a composite food product capable of long-term storage, the method comprising: fully mixing a proper amount of water and food materials at a high temperature to form a first mixed solution; stewing the first mixed solution for at least 30 minutes to thoroughly cook the food material; washing the food material with low temperature ice water; sufficiently mixing the food material with malt syrup at a reaction temperature of less than 110 ℃ to form a composite food and reacting for 10 seconds to 15 minutes to coat and infiltrate the malt syrup into the food material, wherein the malt syrup content is 5 to 30 parts by weight based on 100 parts by weight of the total amount of the food material and the malt syrup; refrigerating and preserving the composite food composed of the food material and malt syrup.

As described above, the composite food produced by simply combining malt syrup with the food materials can preserve the freshness of the food materials without using preservatives. When a large batch of compound food prepared by the method is refrigerated, stored and taken out for repeated heating for many times, the food materials in the compound food still keep the taste and freshness after being heated for 10-15 minutes. In some embodiments, the malt syrup may be mixed with an amount of cocoa, matcha powder or coffee and the food material such that the cocoa, matcha or coffee ingredient may coat the surface of the food material.

The above description is provided to clarify the object of the present invention and the technical means for achieving the object. The present invention will become apparent to the reader from the following description of the preferred embodiments, taken in conjunction with the accompanying drawings and the appended claims.

The following description of the embodiments of the present invention is provided for illustrative purposes, and the present invention is not limited to the embodiments described herein. Moreover, the invention is capable of other embodiments and of being practiced and carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit of the present invention.

The present invention will be described with respect to preferred embodiments and aspects, and such description will explain the structure of the invention by way of illustration only and not by way of limitation of the claimed invention. Thus, the present invention is capable of embodiments in addition to those described herein.

Referring to fig. 1, according to an embodiment of the composite food 100 capable of being stored for a long time produced by the manufacturing method of the present invention, the malt syrup 102 is coated and permeated into the surface 1041 of the food material 104 by the manufacturing method, that is, the composite food can be divided into an inner layer and an outer layer, the inner layer is the food material 104, the outer layer is the malt syrup 102, and in order to coat the malt syrup 102 on the surface 1041 of the food material 104, the temperature of the food material 104 and the malt syrup 102 when mixed needs to be lower than 110 ℃, because the temperature of the malt syrup 102 and the food material 104 when mixed exceeds 110 ℃ causes the malt syrup 102 to be hard to be sufficiently mixed with the food material 104 and difficult to coat on the surface 1041 of the food material 104. In addition, if the temperature during the mixing process exceeds 110 ℃, the hardened malt syrup 102 is also difficult to infiltrate into the surface 1041 of the food material 104, and thus the structure 100 of the composite food product as produced by the method of the present invention is difficult to produce.

Referring to the method shown in FIG. 2, a method for manufacturing a composite food with long shelf life is provided, in which a composite food is produced by the above-mentioned manufacturing method, and the food material in the composite food is coated with malt syrup, and the following steps 202 and 210 of the present invention are described in detail.

As shown in step 202, an appropriate amount of water is mixed with the food material 104 at an elevated temperature to form a first mixture.

In step 204, the first mixture is boiled for at least 30 minutes to cook the food material 104.

In step 206, the food material 104 is washed with low-temperature ice water. In one embodiment, the foregoing steps are used to wash away other impurities not belonging to food materials.

In step 208, the food material 104 and a malt syrup 102 are fully mixed at a reaction temperature lower than 110 ℃ to form a composite food and reacted for 10 seconds to 15 minutes, so that the malt syrup 102 coats and permeates the surface 1041 of the food material 104, wherein the content of the malt syrup 102 is 5 to 30 parts by weight based on 100 parts by weight of the total consumption of the food material 104 and the malt syrup 102. In one embodiment, the reaction time of the composite food is further 1-10 minutes.

In another embodiment, the reaction temperature of the composite food is further 100 ℃. In an embodiment, the reaction temperature of the composite food is further normal temperature.

The composite food product is stored under refrigeration, as shown in step 210. The composite food composed of the food material 104 and the malt syrup 102 produced by the steps of the method can be stored for at least 1 month through refrigeration and still can maintain the taste of the food material.

When the above steps are completed to produce the composite food of the present invention, the composite food composed of the food material and the malt syrup can be further filled into a package bag, and the air in the package bag is pumped out and then sealed.

In one embodiment, when a large batch of composite food prepared by the method is refrigerated and stored and taken out for repeated heating for multiple times, only 10-15 minutes are needed for heating, and the structure of the composite food can still effectively keep the original taste of the food material. In some embodiments, the heating mode during repeated heating can adopt water heating. In some embodiments, the food material may be selected from starch products (e.g., pearl balls), fruits, and the like.

In an embodiment, the food material may further be pearl balls, so when the pearl balls are applied to a large amount of composite food prepared by the preparation method of the present invention, the steps of the method are as follows: mixing a proper amount of water and the pearl powder balls at a high temperature to form a first mixed solution; stewing the first mixed solution for at least 30 minutes to make the pearl powder round and well cooked; washing the pearl balls with low-temperature ice water; fully mixing the pearl pearls and malt syrup at a reaction temperature lower than 110 ℃ to form a composite food, and reacting for 10 seconds to 15 minutes to coat and infiltrate the malt syrup into the pearl pearls, wherein the malt syrup content is 5 to 30 parts by weight based on 100 parts by weight of the total usage amount of the pearl pearls and the malt syrup; refrigerating and storing the composite food composed of pearl powder balls and malt maltose. In some embodiments, the above embodiments can be extended, the malt syrup can be boiled with fruits (such as dragon fruit containing natural pigment or other colored fruits) at low temperature to obtain natural color, and then combined with the pearl balls to form natural color fruit pearl balls. On the other hand, the compound food formed by combining malt syrup and natural pearl balls can be stored for at least 1 month through refrigeration and still can maintain the taste of the pearl balls.
