Technical Field

The present invention relates to soup tablets, in particular to a process for preparing soup tablets. The method comprises co-processing a salt-starch-fibre mass and mixing the co-processed salt-starch-fibre mass with at least one further ingredient selected from salt, sugar, MSG, flavourings, fillers, oils, fats or any combination thereof to obtain a dried mass, and compressing the dried mass into tablets and packaging the tablets.

Background

Soup tablets formed by compressing various ingredients into a tablet shape (e.g., a cube) are widely used as concentrates for preparing a soup, broth, or soup. The soup pieces are typically added to a hot aqueous solution to dissolve them. In addition, soup pieces can be used as a seasoning product when preparing other dishes. The dissolution time of a soup tablet is highly dependent on its compactibility, which can be measured/expressed by the hardness of such a product. The reason for compacting powders in a regular form offers several advantages for commercialization (e.g. reduced volume, optimized use of packaging materials, shelf life and convenience). The habit of users of soup slices is to break the slices or pieces into a dish during the preparation process to ensure good distribution and or to speed up their dissolution time in the boiling water. This friability is one of the attributes that needs to be ensured during shelf life, and therefore post-hardening of the sheet or block must be avoided. It is desirable to have a minimum stiffness in order to wrap the sheet. The maximum stiffness ensures that the average user can break the pieces with his fingers without using additional tools or implements. A typical soup slice or soup cube comprises salt, taste enhancing compounds such as monosodium glutamate (MSG), sugar, starch or flour, fat, flavour components, vegetables, meat extracts, flavours, colours and the like. The amount of each compound may vary depending on the particular purpose of the product, the market, or the taste of the consumer for which it is intended.

A conventional method of making soup tablets involves mixing powdered soup ingredients with fat and compressing the mixture into tablets. In this type of soup slice fat is the main ingredient keeping the structure together.

The present nutritional trend is to avoid or at least reduce consumption of fats rich in saturated fatty acids, and preferably to consume oils rich in monounsaturated fatty acids and/or polyunsaturated fatty acids. WO2004/049831 describes a possible method for trapping very little solid fat in hard soup tablets, provided that the tablets also comprise crystals, a filler and a binder. The binder may comprise ingredients whose addition (sufficient increase in bound water activity) imparts to the final mixture a glass transition temperature that can be exceeded relatively easily during tableting. Such ingredients include meat extracts, process flavours and/or vegetable extracts.

The binder used to bind together low fat soup pieces is usually a hygroscopic amorphous ingredient. These hygroscopic amorphous ingredients are activated in the soup mix by the addition of water. This water addition process can cause problems, such as difficulty in ensuring uniform distribution of water, and requires storage times of up to 24 hours to reach water activity equilibrium. There is a possibility of skin formation which requires the stirrer to be switched off for cleaning. Lumps sometimes form in the mixture, which leads to quality defects in the finished compressed tablet. In addition, soup tablets may develop posterosclerotic.

There is therefore a continuing need in the art to find improved methods for forming soup tablets, especially soup tablets using new binding systems, despite the presence of well-known amorphous binding and/or fat-binding systems.

Disclosure of Invention

It is an object of the present invention to improve the state of the art and to provide an improved solution that overcomes at least some of the inconveniences described above or at least to provide a useful alternative. The object of the invention is achieved by the subject matter of the independent claims. The dependent claims further develop the idea of the invention.

Accordingly, the present invention provides in a first aspect a process for producing soup pieces comprising salt, fibre and starch, the process comprising the steps of:

a) dissolving the salt or a portion of the salt in water;

b) mixing the combination of starch and fiber with water before, during, or after the salt or the portion of the salt is dissolved in water;

c) drying the mixture of step b) to obtain a dried salt-starch-fibre mass;

d) optionally grinding the dried salt-starch-fiber mass;

e) mixing the dried salt-starch-fiber mass with at least one additional ingredient selected from the group consisting of salt, sugar, MSG, flavoring, bulking agent, coloring agent, oil, fat, or any combination thereof, to obtain a dried composition;

f) Compressing said dried composition into a soup slice;

wherein the soup slice comprises at least 10 wt% of a salt-starch-fiber dough; and wherein the salt-starch-fiber mass comprises 18 to 82 wt% salt and 18 to 82 wt% of a combination of starch and fiber, and wherein the salt is dissolved in water in a ratio between 1:2.8 to 1: 20.

In a second aspect, the present invention relates to a soup slice obtainable by the method of the invention.

The inventors have surprisingly found that the use of a co-processed salt-starch-fibre mass has very good flow ability values and provides a new binding system that is effective in soup tablets.

The use of the salt-starch-fibre dough enhances the hardness of the soup tablets/chunks after compression. The hardness obtained may exceed the hardness normally observed during pressing of soup cubes/tablets. Meanwhile, the produced soup product is still easy to break. So far, this behavior has not been observed for similar hardness values. This strongly indicates that a different new bonding mechanism exists. Thus, the block/tablet can be easily produced (high hardness facilitates manufacturing), but at the same time exhibits good friability. Friability is a key driver of consumer liking and is therefore desirable. Furthermore, the soup slices/chunks have a faster dissolution time compared to standard soup slices/chunks. This is very surprising, since the dissolution time is expected to be slower due to the higher hardness.

In addition, the salt-starch-fiber dough is used to produce soup cubes with reduced salt content (e.g., between 10% to 50% reduction). Surprisingly it was found that even with high fibre content the block/tablet can be pressed (the fibres are elastic and can cause covering/breakage after pressing). This behavior can be explained by entrapment of salts in starch and fiber. Which enables the use of higher amounts of starch and fiber in the application. It should also be mentioned that the use of a salt-starch-fibre mass has a positive effect on the flow capacity compared to pure starch.

One aspect of the present invention provides a soup slice obtained (e.g. obtainable) by the method of the present invention.

By "soup tablets" is meant tablets obtained by compressing free flowing powders into tablets. Tablets may be of any shape that can be formed in a tablet press; many commercial soup tablets are cubes. Soup tablets are sometimes referred to as bouillon tablets, stock solution tablets or seasoning tablets. In the form of chunks, they are referred to as soup chunks, bouillon chunks, stock solution chunks or seasoning chunks.

By "salt" according to the invention is meant an edible salt capable of imparting or enhancing the perception of saltiness. The salt is selected from sodium chloride, potassium chloride, ammonium chloride or a combination thereof, more preferably sodium chloride. In another embodiment, the soup slice packet comprises salt in the range of 10% to 65% (by weight of the composition), preferably between 15% to 65%, preferably between 20% to 60%, preferably between 25% to 60%, preferably between 30% to 60%, preferably between 35% to 50%, preferably between 40% to 60%, preferably between 45% to 55%, preferably between 40% to 50% (by weight of the composition).

The term "dissolved" according to the invention means that the salt is dissolved in water. In one embodiment, the salt is dissolved in water in a ratio of between 1:2.8 and 1:20, preferably 1:2.8 and 1:15, preferably 1:2.8 and 1:10, preferably 1:2.8 and 1:6, preferably 1:3 and 1:20, preferably 1:3 and 1:15, preferably 1:3 and 1:10, preferably 1:3 and 1:6, preferably 1:4 and 1:20, preferably 1:4 and 1:15, preferably 1:4 and 1:10, preferably 1:4 and 1: 6. In a preferred embodiment, a saturated water-salt solution is obtained. In one embodiment, the combination of starch and fiber is mixed with water after the salt or portion of salt is dissolved in the water. The term "part of the salt" means that not the total amount of salt of the soup slices is dissolved in water, as the salt can also be mixed in the dry composition as pure salt. At least 8% of the total amount of salt is dissolved in water, preferably at least 12%, preferably at least 20%, preferably at least 25%, preferably at least 30%, preferably at least 40%, preferably at least 50%, preferably at least 60%, preferably at least 75%, preferably at least 80%, preferably at least 90%, preferably between 8% and 100%, preferably between 12% and 100%, preferably between 20% and 100%, preferably between 30% and 100%, preferably between 40% and 100%, preferably between 50% and 100%, preferably between 75% and 100%, preferably 100% of the total amount of salt is dissolved in water.

In another embodiment, the soup slice packet comprises monosodium glutamate (MSG) in the range of 0% to 25% (by weight of the composition), preferably between 0% to 15%, preferably between 0.5% to 25%, preferably between 0.5% to 15%, preferably for example between 5% to 10% (by weight of the composition).

In another embodiment, the soup slice packet comprises a sugar (e.g. sucrose) in the range of 0% to 20% (by weight of the composition), preferably between 0% to 15%, preferably between 0.5% to 15%, preferably between 5% to 15%, preferably between 2% to 10% (by weight of the composition). The sugar according to the invention is white sugar or brown sugar.

The "starch" according to the invention has two main polysaccharides amylose and amylopectin. Starch granules can be isolated from a wide variety of plant sources consisting of tuber roots, tubers and seeds. Starch granules appear to be of different shapes, sizes and have varying amylose/amylopectin ratios based on the botanical source. The starch according to the invention is a native starch, a flour, a pregelatinized starch or a cold swelling starch or a combination thereof. The starch according to the invention is selected from the group consisting of maize, waxy maize, high amylose maize, wheat, tapioca, rice, potato, tapioca or a combination of these. The corresponding flour can also be used as a source of starch. The person skilled in the art calculates the amount of flour to be used which falls within the scope of the invention on the basis of the amount of starch. Native starch is defined as being in its native form in nature; starch granules isolated using extraction methods, or of commercial origin, because naturally occurring native starch is insoluble in cold water. The native starch granules are in semi-crystalline form and have a crystallinity varying from 15% to 45%. A further distinguishing feature of native starch granules is their presence of maltose cross-over when viewed under polarized light. Due to the order present in native starch, it exhibits birefringence under polarized light. Gelatinized starch is native starch, which undergoes a gelatinization process. When the native starch granules are gradually heated to higher temperatures in the presence of excess water, a gelling process occurs, the granules begin to swell irreversibly, and there is a point where the maltose of the native granules cross-disappears. During gelation, several events occur simultaneously. There are three distinct stages that occur during gelation: (i) carrying out granular swelling by slowly absorbing water; (ii) followed by rapid birefringence loss via absorption of large amounts of water by the pellets; and (iii) finally, leaching the soluble fraction into a solution to transform the particles into an invisible pouch. The loss of size, shape and birefringence of the particles is a unique feature of gelatinized starch. Gelatinized starch is commercially available as pre-gelatinized starch. When the native starch granules are gradually heated to a higher temperature in the presence of excess water, swollen starch granules or partially gelatinized starch granules are produced; the granules begin to swell irreversibly and the swollen starch granules or partially gelatinized starch granules are an intermediate stage between the native starch granule form and gelatinization. The swollen form of the particles has a larger particle size than native starch particles and may have a partial or complete loss of birefringence.

The "fiber" according to the present invention is a dietary fiber, cereal bran or a combination thereof. Dietary fiber is composed of residues of edible plant cells, polysaccharides, lignin and associated substances that resist digestion by human digestive enzymes (hydrolysis). The dietary fiber is derived from vegetables, fruits, grains, or combinations thereof. The dietary fiber is selected from at least one of carrot, beetroot, pumpkin, orange, wheat, oat, bamboo, tomato, bell pepper, leek, ginger, onion, kale, parsnip, celery, cucumber, zucchini, cauliflower, kohlrabi, asparagus or combinations thereof, preferably carrot, beetroot, pumpkin, citrus, wheat, oat, bamboo, tomato or combinations thereof. The "bran" according to the invention is the outer layer of the grain, which consists of the pericarp, the testa, the aleurone layer germ, and may comprise a portion of the starchy endosperm. Commercial bran preparations contain varying amounts of starchy endosperm and germ depending on the type of grain and milling process. Bran is obtained primarily from grain cereals such as barley, buckwheat, ground dry wheat, maidenhair, common oats (Avena sativa, also referred to herein as oats), corn, millet, rice (e.g., black rice, brown rice, and/or wild rice), rye, sorghum, emmer, teff, triticale, wheat, and wheat grains. A more preferred whole grain cereal is a cereal from a monocotyledonous plant of the family poaceae (poaceae), which is cultivated for edible starch grains. Plant species that do not belong to the family poaceae but also produce starch-containing seeds or fruits that can be used in the same manner as cereal grains are called pseudocereals. Examples of pseudocereals include amaranth, buckwheat, tartary buckwheat, and quinoa. As used herein, the term "grain" includes grains and pseudograins, unless the context clearly indicates otherwise; and the bran used herein may be from any type. Typically, the source of the grain used depends on the product to which it is added, as each grain has its own taste profile.

In one embodiment of the present invention, the cereal bran is selected from rice bran, wheat bran, buckwheat bran, corn bran, oat bran, barley bran, or combinations thereof.

Depending on the type of cereal grain, bran constitutes about 3% to 30% of the dry weight of the grain. The main component of bran is dietary fiber. In one embodiment of the invention wherein the bran is derived from whole grain of wheat, the bran may usefully comprise the following amounts of components: 30-70% (w/w) of fiber, 20-50% (w/w) of starch, 5-20% (w/w) of protein and 0.5-10% (w/w) of fat.

The bran in the composition of the present invention may optionally be heat treated and may be coarse or powdered to reduce its particle size and achieve defined particle characteristics. In a preferred embodiment, the bran is a powdered cereal bran. Methods for producing powdered bran are known to those skilled in the art.

In one embodiment of the invention, the cereal bran contained in the tablets of the invention is ground. Preferably, the cereal bran is dry milled. Typically, milling converts the cereal bran to a more palatable form by reducing the particle size of the bran. The grinding of the bran has the following advantages: such as improving the homogeneity of the final product, i.e. improving the mixing efficiency of the bran and other ingredients, increasing the binding capacity between the different ingredients, improving the digestibility of the bran by the consumer. The grinding preferably reduces the particle size of the cereal bran.

The fibres (dietary fibres, cereal bran or a combination thereof) are in powdered form having a particle size of from 5 μm to 1000 μm, preferably from 5 μm to 800 μm, preferably from 5 μm to 700 μm, preferably from 5 μm to 500 μm, preferably from 15 μm to 1000 μm, preferably from 15 μm to 700 μm, preferably from 15 μm to 500 μm, preferably from 20 μm to 500 μm, preferably from 50 μm to 800 μm, preferably from 5 μm to 500 μm, preferably from 75 μm to 700 μm, preferably from 80 μm to 500 μm, preferably from 100 μm to 600 μm, preferably from 100 μm to 500 μm, preferably from 250 μm to 500 μm. The particle size and particle size distribution can be measured by laser diffraction using a malvern particle size analyzer (malvern mastersizer).

The combination of starch and fiber may be mixed in any ratio, preferably between 99.9:0.1 to 0.1:99.9 (by weight of the combination of starch and fiber), preferably between 99.5:0.5 to 0.5:99.5, preferably between 99:1 to 1:99, preferably between 95:5 to 5: 95; preferably between 90:10 and 10:90, preferably between 80:20 and 20:80, preferably between 70:30 and 30:70, preferably between 60:40 and 40:60 (by weight of the combination of starch and fiber).

The term "flavouring agent" according to the present invention means an ingredient selected from the group consisting of yeast extract, vegetable powder, animal extract, bacterial extract, vegetable extract, animal powder, reaction flavouring, hydrolysed vegetable protein, acid, ingredients (garnishes), herbs, spices or combinations of these. The soup slice according to the invention comprises 0% to 40% flavouring agent, preferably 0.5% to 40%, preferably 1% to 40%, preferably 2% to 40%, preferably 1% to 35%, preferably 2% to 35%, preferably 3% to 35%, preferably 5% to 35%, preferably 9% to 35%, preferably 10% to 30%, preferably 10% to 25%, preferably 10% to 20%, preferably 5% to 25%, again such as 5% to 15% (by weight of the composition). In one embodiment, the flavoring agent is selected from the group consisting of yeast extract, chicken extract, onion powder, garlic powder, celery root powder, tomato powder, bacterial extract, reaction flavoring agents, or combinations of these. Bacterial extracts are described in WO2009040150 or WO 2010105842. Vegetable extracts are described in WO 2013092296. The vegetable powder is at least one of onion powder, garlic powder, tomato powder, celery root powder, or their combination. The ingredient, herb, spice, or combination thereof is selected from parsley, celery, fenugreek, angelica, rosemary, marjoram, dill, tarragon, coriander, ginger, lemon grass, yellow ginger, chili, ginger, paprika, mustard, garlic, onion, turmeric, tomato, coconut milk, cheese, oregano, thyme, basil, paprika, sweet pepper, mexican pepper, white pepper, and black pepper, or a combination of these. Animal powder means at least one ingredient of meat powder, fish powder, crustacean powder or a combination thereof. Meat powder means chicken powder or beef powder. By animal extract is meant at least one component of meat extract, fish extract, crustacean extract or a combination thereof.

It would be advantageous to provide a hard soup tablet containing only or predominantly oil that is liquid at ambient temperature in local conditions and no or only a small amount of solid fat. In one embodiment, the soup slice comprises less than 5% saturated fat; preferably no fat (0 wt.% fat).

In one embodiment, the soup slice further comprises an oil, for example up to 15% oil, as well as up to 10% oil, preferably the composition comprises an oil in an amount in the range of 0% to 15% (by weight of the composition), preferably between 0.5% to 10% (by weight of the composition), preferably between 0.5% to 7%, preferably between 0.5% to 5%, preferably between 0.5% to 3% (by weight of the composition). In a preferred embodiment, the oil is a vegetable oil. Preferably, the oil is selected from sunflower oil, rapeseed oil, cottonseed oil, peanut oil, soybean oil, olive oil, coconut oil, algae oil, safflower oil, corn oil, rice bran oil, sesame oil, hazelnut oil, avocado oil, almond oil, walnut oil or combinations thereof; more preferably sunflower oil. The term sunflower oil also includes high oleic sunflower oil. In the context of the present invention, the term "oil" refers to triglycerides that are liquid or pourable at room temperature of 20 ℃, for example triglycerides that are liquid or pourable at room temperature of 25 ℃. The oil has a solid fat content of less than 10% at 20 ℃, preferably less than 5% at 20 ℃, preferably less than 2% at 20 ℃, preferably 0% at 20 ℃. The oil may be rich in monounsaturated fatty acids and polyunsaturated fatty acids.

The term "bulking agent" according to the present invention means maltodextrin, glucose syrup, starch, flour or a combination thereof. In one embodiment, the soup slice packet according to the method of the invention comprises a filler in the range of 0% to 30% (by weight of the composition), preferably between 0.5% to 25%, preferably between 0.5% to 20%, preferably between 0.5% to 15%, preferably between 5% to 20%, preferably between 5% to 15%, preferably between 5% to 10% (by weight of the composition). In one embodiment, the soup slice according to the method of the invention comprises less than 10% maltodextrin and/or glucose syrup, preferably less than 5%, preferably less than 1% (by weight of the composition), e.g. it may be free of maltodextrin and/or glucose syrup. The soup slices do not contain maltodextrin. The soup slice does not contain glucose syrup. It was found that replacing maltodextrin with wet native starch reduces undesirable texture changes such as post-hardening. Maltodextrin and, to a lesser extent, glucose syrup are not common ingredients in the household kitchen and may therefore be a doubt by some consumers. In this context, glucose syrup and maltodextrin are a mixture of D-glucose units linked in chains of variable length, produced by hydrolysis of starch. Glucose syrups and maltodextrins are classified by DE (dextrose equivalent). Typically, maltodextrins have a DE between 3 and 20, whereas glucose syrups have a DE higher than 20. The term "starch" according to the invention means native starch or flour. Native starch is typically obtained from grains and tubers by physical extraction, purification and drying of starch milk. The starch according to the invention is selected from the group consisting of corn, waxy corn, high amylose corn, wheat, tapioca, potato, rice, tapioca or a combination of these. The starch is selected from the group consisting of native wheat starch, native corn starch, native rice starch, native potato starch, native tapioca starch, and combinations of these. The starch according to the invention comprises between 3 and 25 wt.% moisture. For example, starch comprises between 4 and 22 wt.% moisture, preferably between 7 and 21 wt.% moisture, preferably between 19 and 21 wt.% moisture (wet starch). In one embodiment, the wet native starch has a water activity at 20 ℃ of between 0.4 and 0.6, preferably at 20 ℃ of between 0.45 and 0.55. Wet native starch with appropriate moisture content can be obtained by blending wet and non-wet starches and allowing them to equilibrate. Wet native starch is generally commercially available at a lower price than dry native starch, which is actually a semi-finished ingredient because of the need to remove water from the starch during the manufacturing process. In another embodiment, the soup slice packet comprises starch in the range of 0% to 20% (by weight of the composition), preferably between 0.1% to 20%, preferably between 0.1% to 15%, preferably between 0.1% to 10%, preferably between 1% to 10%, preferably between 3% to 10% (by weight of the composition). The flour according to the invention is wheat flour, tapioca flour, corn flour or a combination thereof. In another embodiment the soup-slice packet comprises flour in the range of 0% to 20% (by weight of the composition), preferably between 0.1% to 20%, preferably between 0.1% to 15%, preferably between 0.1% to 10%, preferably between 1% to 10%, preferably between 3% to 10% (by weight of the composition).

The "salt-starch-fibre mass" according to the invention is an aggregate of starch and fibres, wherein the salt crystallizes in, on and through the aggregated starch and fibres with surface protrusions of the salt, and the particle size of the salt is between 0.5 μm and 50 μm, preferably 0.5 μm and 30 μm, preferably 0.5 μm and 10 μm, preferably 1 μm and 50 μm, preferably 1 μm and 30 μm, preferably 1 μm and 10 μm, preferably 1.5 μm and 50 μm, preferably 1.5 μm and 30 μm, preferably 1.5 μm and 10 μm, preferably 2 μm and 50 μm, preferably 2 μm and 30 μm, preferably 2 μm and 10 μm. The salt-starch-fiber mass is not hollow. The dried salt-starch-fibre mass has a particle size distribution with a median diameter Dv50 in the range of 20 to 1500 μm, preferably in the range of 50 to 1000 μm, preferably in the range of 50 to 800 μm, preferably in the range of 50 to 500 μm, preferably in the range of 100 to 450 μm, preferably in the range of 200 to 450 μm, preferably in the range of 300 to 450 μm. In another embodiment, the salt-starch-fiber mass comprises 18% to 82% salt (by weight of the salt-starch-fiber mass) and 18% to 92% of a combination of starch and fiber (by weight of the salt-starch-fiber mass), preferably 20% to 80% salt and 20% to 80% of a combination of starch and fiber, preferably 25% to 75% salt and 25% to 75% of a combination of starch and fiber, preferably 30% to 70% salt and 30% to 70% of a combination of starch and fiber, preferably 40% to 60% salt and 40% to 60% of a combination of starch and fiber, preferably 50% salt and 50% of a combination of starch and fiber (by weight of the salt-starch-fiber mass). In another embodiment, the soup slice comprises at least 10% (by weight of the composition) salt-starch-fibre mass, preferably at least 15%, preferably at least 20%, preferably in an amount in the range of 10% to 100% (by weight of the composition), preferably between 10% to 90%, preferably between 10% to 80%, preferably between 10% to 70%, preferably between 15% to 100%, preferably between 15% to 90%, preferably between 15% to 75%, preferably between 20% to 100%, preferably between 20% to 90%, preferably between 20% to 80%, preferably between 20% to 75%, preferably between 20% to 70%, preferably between 25% to 100%, preferably between 20% to 70%, preferably between 25% to 65% (by weight of the composition). In another embodiment, the salt-starch-fiber mass does not contain added acid, added gum, added hydrocolloid, or a combination thereof. The gum according to the present invention is xanthan gum, carrageenan, locust bean gum, agar, alginate, guar gum, gum arabic, gellan gum or a combination thereof. In case of using native starch, it may be beneficial if the mixture of native starch, fiber, salt and water is heated (cooked) to a temperature between 60 ℃ and 100 ℃ for at least 30 seconds, preferably between 0.5 minutes and 15 minutes. This heating (cooking) results in the native starch material being swollen starch granules or partially gelatinized starch, resulting in an even harder sheet/piece.

The particle size Dv50 is used in the conventional sense as the median value of the particle size distribution. The median value is defined as the value at which half of the population resides above the point and half below the point. Dv50 is the size in microns that separates the volume distribution from more than half and less than half of the diameter. Particle size distribution can be measured by laser light scattering, microscopy or microscopy in combination with image analysis. For example, the particle size distribution can be measured by laser light scattering. Since the main result of laser diffraction is volume distribution, Dv50 is cited as the volume median.

The drying step can be carried out by any generally known drying technique, such as air drying, oven drying, drum drying, vacuum drying, bed drying, microwave vacuum drying, infrared radiation drying, or combinations thereof. The drying step does not include spray drying. In one embodiment of the invention, the drying is done at a temperature between 50 ℃ and 150 ℃, preferably between 50 ℃ and 120 ℃, preferably between 60 ℃ and 100 ℃, preferably between 65 ℃ and 120 ℃, preferably between 65 ℃ and 100 ℃, preferably between 65 ℃ and 90 ℃, preferably between 65 ℃ and 80 ℃.
