Description

  The present invention relates to livestock meat or livestock meat-like processed foods. Specifically, the present invention relates to livestock meat or livestock meat-like processed foods using structured soy protein.

  In recent years, the social situation surrounding livestock meat materials has become severe, and plant proteins such as soybean protein have been increasingly used as an alternative raw material or an extender for livestock meat. Powdered soy protein materials, such as isolated soy protein and concentrated soy protein, are used as raw materials for traditional protein foods such as cancer throbbing, deep-fried chicken, deep-fried oil, and Takano tofu, seafood paste products, hams and sausages . On the other hand, structured soy protein, which is organized using defatted soy beans and powdered soy protein materials as raw materials, is also used for various purposes, and among them processed meat products such as hamburger and meatballs as an extender for minced meat Granular textured soy protein is used. This textured soy protein is in the form of a puffed puff, and is used mainly for the purpose of imparting a grain feel of ground meat.

  On the other hand, there are several types of textured soy protein, in which the tissue is oriented like meat fibers. This textured textured soy protein is a fried chicken-like food, a meat steak-like food. It has been developed as an imitation of meat itself such as scallop-like foods and crab leg-like foods (Patent Documents 1 to 6 etc.). Such oriented textured soy protein is intended to imitate a fibrous structure such as steak when raw meat is heated as it is (meat analog), so use ground meat such as hamburger or meatballs, etc. It is not expected to be used for processed meat and its imitation.

  Further, as a related technique for imparting a flesh-like fiber feeling, there is a technique for blending fibrous soybean protein (Patent Document 7 or the like). The fibrous soy protein is a fine thread-like shape obtained by discharging an aqueous slurry or paste of soy protein raw material from a small-diameter back pressure orifice while flowing under heating, and making it into a fiber. It is distinguished from granular or ground-like textured soybean protein in terms of manufacturing method and shape. Since this fibrous soy protein contains a lot of water and is usually frozen, it does not have the function of adjusting the water content of the whole raw material like the granular or ground meaty soy protein, which is a dry product, and it takes time to thaw. It was difficult to use.

JP 58-201947 A Japanese Patent Laid-Open No. 61-224941 JP-A-6-217704 Japanese Patent Laid-Open No. 7-8177 JP-A-8-66157 JP 2000-279099 A JP 63-160554 A

  However, because the actual minced meat has a certain degree of meat-specific fiber feeling as well as the grain feeling, even if a large amount of granular or ground-like textured soy protein is used, the ground meat has a realistic, fibery feel. It was difficult to reproduce the feeling. Therefore, there was a tendency for the texture that was not ground meat to stand out as the amount of ground meat used was reduced and the textured soy protein was increased.

  In view of such circumstances, the present invention is a technique that can improve the texture of livestock processed foods mainly composed of meat, or reduce the use of meat without damaging the texture, or the amount of meat used It is an object of the present invention to provide a technique capable of reproducing a fiber feeling equivalent to meat in a livestock meat-like processed food that is little or substantially unused.

  In view of the above problems, the present inventors tried to add a textured soybean protein of a type having orientation to livestock meat or livestock meat-like processed food. And, as a result of further earnest research, it is not a simple soy protein with orientation, but rather a flat shape with orientation and thin thickness, having a specific size The knowledge which can solve the said subject was obtained, without reducing manufacturing efficiency by using textured soybean protein.

That is, the present invention
(1) A textured soy protein having a flat shape with a major axis of 10 to 70 mm and a thickness of 1 to 8 mm and having orientation is rehydrated, mixed with a binding raw material, and the resulting dough is molded, A method of producing livestock meat or processed meat-like processed food characterized by heating,
(2) The method for producing livestock meat or livestock meat-like processed food according to (1), wherein the major axis / minor axis ratio is 1.1 or more,
(3) The method for producing livestock meat or processed meat-like processed food according to the above (1), which further uses a granular textured soy protein having no orientation,
(4) The method for producing a processed meat-like processed food according to (1) above, wherein the binding raw material is a powdery soy protein material and / or livestock meat,
(5) The method for producing a livestock meat-like processed food according to (4), wherein egg white is further mixed as a binding raw material,
(6) The method for producing a processed meat product according to (1), wherein the meat content is 30% by weight or more in the raw material,
(7) The method for producing a livestock meat-like processed food according to (1), wherein the meat content is less than 30% by weight in the raw material,
(8) The method for producing livestock meat-like processed food according to (7), wherein the meat content is 0% by weight in the raw material,
(9) A livestock meat or livestock meat-like processed food characterized by using a textured soybean protein having a flat shape with a major axis of 10 to 70 mm and a thickness of 1 to 8 mm and having orientation.

  According to the present invention, it is possible to improve the texture of ground meat in a processed meat product without reducing the production efficiency, and to reduce the amount used without impairing the texture of ground meat. It becomes possible to do. Further, the amount of minced meat used can be reduced without reducing the production efficiency of livestock meat-like processed foods having a texture equivalent to that of minced meat. In particular, according to the present invention, a so-called meatless hamburger-like food or meatball-like food can be imparted with a texture comparable to that of livestock meat.

  The livestock meat or processed meat-like processed food of the present invention has a flat shape having a major axis of 10 to 30 mm and a thickness of 1 to 5 mm, and a larger shape having a major axis of 10 to 70 mm and a thickness of 1 to 8 mm, and orientation. It is characterized by using a textured soybean protein having Hereinafter, the present invention will be specifically described.

(Livestock meat or processed meat-like food)
In the present invention, livestock meat or livestock meat-like processed food is a general term for livestock meat processed food and livestock meat-like processed food. In general, there is no clear boundary between them, but in the present invention, “livestock processed food” in the raw material is “processed livestock meat”, which is the same form as this livestock meat processed food. “Meat-like processed foods” are those that use less than 30% by weight of livestock meat. Those with 0% by weight of livestock meat are called meatless processed meat-like processed foods. Livestock meat such as cattle, pigs, chickens, horses and sheep can be used as livestock meat. What is necessary is just to determine the usage-amount of livestock meat suitably according to the quality and concept which are requested | required of a product. For example, if meatless food is used, no meat is used.

  Livestock meat or processed meat-like processed foods are generally prepared by mixing raw materials mainly composed of binding materials with a kneader such as a mixer or silent cutter, forming the dough into a suitable size and shape, It is obtained by heating by frying or baking and heat setting. The obtained food can be refrigerated or frozen for distribution, and the consumer can cook directly, such as microwave oven, stew, fry, baking, etc., or the retailer or restaurant can cook indirectly, To be served.

  Examples of processed meat products include hamburger, patties, meatballs, nuggets, meatballs, ham, sausages, dumplings, grilled rice, meat buns, small bowls, minced cutlet, meat pie, ravioli, lasagna, meatloaf, roll cabbage, peppers , Deep-fried chicken, and other processed foods using various types of minced meat. “Processed food” means that food such as steak and pork cutlet that has been heat-treated without breaking the meat tissue itself with a chopper or the like is not included. The examples of processed meat products listed above are examples of food forms, and it is of course possible to improve the texture of livestock meat by replacing some of the livestock meat with other alternative ingredients. In the category of processed foods, for example, such food forms can be adopted.

  In the case where the livestock meat or livestock meat-like processed food is a livestock meat processed food containing 30% by weight or more of livestock meat, in the present invention, the structured soy protein having a specific shape and orientation is partially replaced with livestock meat. It is possible to reduce the use amount of livestock meat while maintaining the fiber feeling of livestock meat, to reduce the cost, or to give the fiber feel by livestock meat and improve the quality.

  In addition, in the case of processed meat-like processed foods with a meat content of less than 30% by weight, the present invention uses a textured soy protein having a specific shape and orientation as the main raw material, so that it is more meat-like than conventional similar products. The fiber texture is imparted, and a texture equivalent to that of meat-based processed meat foods can be imparted.

(Dough and binding material)
Processed livestock meat products and livestock meat-like processed foods typically have different dough binding materials. The binding raw material is a raw material having a role of connecting raw materials together in the dough. In general, processed meat products are prepared by kneading a raw material of beef, pork, chicken, etc., which is ground meat, etc., as a binding material to prepare a meat dough. In the case of processed meat-like processed foods, for example, a soybean protein dough can be prepared by adding powdered soybean protein material such as isolated soybean protein or concentrated soybean protein as a binding material and adding water or further fats and oils and kneading. All can be prepared according to known methods.

(Powdered soy protein material)
The powdered soy protein material is preferably used as the main constituent material of the dough in the production of processed meat-like processed foods, that is, a binding raw material. It can also be used for the purpose of improving meat quality in the production of processed meat products. As the powdery soy protein material to be used, defatted soymilk powder having a protein content of 60% by weight or more obtained from defatted soybeans, concentrated soy protein or separated soy protein is preferable, and isolated soybeans having a protein content of 85% by weight or more. Protein is more preferred.
In processed meat-based livestock meat processed food, it is preferable to use 1 to 15% by weight of powdered soy protein material in the raw material when used as a meat quality improver.
On the other hand, in particular, processed meat-like foods with a use rate of less than 30% by weight of the meat are used as a binding material for the dough, and the dough is prepared by kneading the powdered soy protein material together with water and further fats and oils. In this case, it is preferable to use 1 to 15% by weight of the powdered soy protein material in the dough.

(Egg white)
In the livestock meat or livestock meat-like processed food of the present invention, egg white can be used as a binding raw material. The egg white can be selected from raw egg white, frozen egg white, and dried egg white. In particular, in a processed meat-like processed food with a low usage rate of livestock meat of less than 30% by weight, it is preferably added when the binding power of the dough after heating tends to be weak and the shape retention tends to decrease. It is preferable to add 0.1 to 5% by weight of egg white as a dry weight in the raw material.

(Orientated textured soy protein)
Granular textured soy protein is generally added to soy protein raw materials such as isolated soy protein, concentrated soy protein, and defatted soy beans, and then heat treated at high pressure using an extruder (extrusion molding machine) to produce a thermoplastic material. Is extruded from a die (die) provided at the tip of the screw, the structure is expanded to a desired degree, and then manufactured through chopping, drying / cooling, and sizing steps. Here, the term “granular” has the widest concept that can be distinguished from “fibrous soy protein”, and its size and shape are not particularly limited, and flat and rod-like ones are also included. Shall.

  On the other hand, “fibrous soy protein” is a kind of structured soy protein, which has a fine thread-like shape, while flowing an aqueous slurry or paste of soy protein raw material under heating. It is produced by discharging it from a small-diameter back pressure orifice and making it into a fiber, and it is stored and distributed after being frozen. Thus, the granular textured soybean protein and the fibrous soybean protein are distinguished from each other in terms of shape and production method.

The textured soy protein used in the livestock meat or processed meat-like processed food of the present invention corresponds to the granular textured soy protein described above, and has a specific shape and is characterized by having an orientation. is there.
The oriented textured soy protein has a property that a fibrous tissue is oriented in a certain direction and is torn in a certain direction like a meat tissue. As a means for imparting such fiber orientation in the textured soybean protein, known techniques including Patent Documents 1 to 6 can be used, and any method that can impart fiber orientation is particularly limited. Is not to be done. Specifically, for example, a method of extruding at a high pressure while suppressing expansion of the raw material by forming a die at the tip of the extruder into a slit shape (Patent Document 1), and a method of blending fats and starches in the raw material (Patent Document 2) Or a method in which soy flour and potato starch or wheat flour are mixed in the raw material, and a high shear force is applied (Patent Literature 3), a method in which wheat gluten and starch are blended in the raw material (Patent Literature 5), What is necessary is just to provide orientation using the method (patent document 6) etc. which mix | blend calcium and starch in a raw material.
Granular textured soy protein may or may not have such orientation. To determine whether or not there is orientation, loosen the textured soy protein with hands or a kneader after reconstitution. In this case, it can be easily determined by observing whether or not a structure oriented in a certain direction appears.

The flat shape having the “specific shape” of the granular textured soybean protein used in the present invention refers to the shape in the state of the dry raw material, and such a shape needs to be maintained in the final processed food. There is no. When this flat shape is represented by a major axis, a minor axis, and a thickness, it means that the major axis is at least 10 to 30 mm and the thickness is 1 to 5 mm. Moreover, it is also possible to have a larger size with a major axis of 10 to 70 mm and a thickness of 1 to 8 mm. By using a larger sized soy protein, the fiber feel of the meat can be further enhanced.
Here, the major axis indicates the longer diameter in a plane perpendicular to the thickness, and the minor axis indicates the shorter diameter in the plane. For example, if the shape of the vertical plane with respect to the thickness is a quadrangle, the long side is the major axis and the short side is the minor axis. If the shape is circular, the maximum value of the diameter is the major axis and the minimum value is the minor axis.
In particular, the major axis is preferably 15 to 30 mm, more preferably 15 to 25 mm. In the case of a larger size, the major axis is preferably 15 to 70 mm, more preferably 20 to 60 mm, and even more preferably more than 30 mm and 60 mm or less.
The minor axis is preferably 1.1 or more when expressed as a major axis / minor axis ratio, more preferably 1.2 to 5, more preferably 1.5 to 5, and more preferably 2 to 4. The value which becomes is more preferable.
The thickness is more preferably 1 to 3 mm, but in the case of a larger size, 2 to 7 mm is also preferable, and more than 3 mm and more preferably mm or less.

The means for forming the granular textured soybean protein into such a specific shape is not limited. For example, a rod-like textured product extruded from a die at the end of the extruder is supplied to a rotary blade type continuous cutter such as a commit roll. As it goes on, it can be continuously cut into a certain range of shapes. By appropriately adjusting the shape of the rotary blade, it is possible to slice into a flat shape having a desired thickness. Alternatively, a flat slit-shaped die can be used as the die at the tip of the extruder, and a method of extruding the die into a flat shape can also be adopted as the molding means.
The oriented textured soy protein formed into a specific shape in this way need not be all, but can have a longer diameter in the direction having the fiber orientation in more grains. Can give a sense of livestock-like fiber. The overall shape can be flat and elongated.

Oriented textured soy protein is mainly used in a relatively large size (for example, major axis 40 mm × minor axis 20 mm × thickness 20 mm) such as the eyebrows shape of the cocoon because it wants to maintain the fiber feel of the meat. However, since granular textured soy protein is dried and solidified, when it is used for the production of livestock meat or processed meat-like processed food, if it is added as it is, the tissue will not be sufficiently softened and processed as a hard tissue. Therefore, the texture is far from fibrous. Therefore, the granular textured soybean protein must have a process of absorbing water in advance and softening the tissue before use, that is, a “water-returning process”.
However, when a large amount of water is added to the eyebrow-like textured soy protein as described above, the specific gravity is light and this will immediately rise, and in order to absorb enough water, it is pressed from above with a weight, etc. It is necessary to soak for a long time, and after the soaking, a step of squeezing water is also necessary. By the way, when a small amount of water is added so that the structured soy protein does not float up, there will be variations in what has been reconstituted and what has not been reconstituted. For this reason, the process of refining a large amount of textured soybean protein of a large size such as eyebrows requires a lot of time and labor, and deteriorates work efficiency.
On the other hand, granular textured soy protein with a fine particle size has a large surface area, so it can be rehydrated even with less water and has good water reversibility. It is difficult to give a feeling of fiber.

In the present invention, by using an oriented textured soy protein having a specific shape, the water can be easily and quickly returned with a specified amount of water, for example, about 2 to 5 times the amount of water with respect to the oriented textured soy protein. Therefore, it is possible to provide excellent work efficiency during use and to give a meat-like fiber feeling. Conventionally, there has been an equivalent to the oriented textured soybean protein of a specific shape in the present invention (for example, Patent Document 1), which is intended to be used for imitation of sliced meat or meat pieces themselves. It is not intended for use in livestock meat or processed meat-like processed foods.
The addition amount of the oriented textured soybean protein is preferably 0.5 to 30% by weight, more preferably 3 to 20% by weight in the raw material.

  For the livestock meat or livestock meat-like processed food of the present invention, the following food ingredients that are usually used can be used as necessary.

(Non-oriented textured soy protein)
In the present invention, in addition to a specific oriented textured soy protein, a granular textured soy protein having no orientation, that is, non-oriented, can also be used. By adding this non-oriented textured soy protein to the dough, it is possible to give a ground meat texture. And by using in combination with the oriented textured soy protein, it is possible to reproduce a more complex texture of meat, which combines the texture of meat with the feel of grain.

(Sub-material)
In the dough, as a secondary material other than the above-mentioned binding raw materials and structured soy protein, in addition to the materials that make up the dough skeleton, such as water, fats and oils, sugars, and seasonings, carrots, burdock, sesame, onions, etc. Solid ingredients to be dispersed in the dough such as vegetables, seaweeds such as seaweed and hijiki.

(Manufacturing method of livestock meat or processed meat-like food)
Next, the manufacturing method of the livestock meat or livestock meat-like processed food of this invention is demonstrated.
The method for producing livestock meat or processed meat-like processed food according to the present invention has a specific shape, that is, a flat shape having a major axis of 10 to 30 mm and a thickness of 1 to 5 mm, and more generally a flat shape of 10 to 70 mm and a thickness of 1 to 8 mm The textured soy protein having an orientation and orientation is rehydrated, mixed with the binding material, and the resulting dough is molded and heated.
First, the dough obtained by kneading the raw materials may be a meat dough using livestock meat as a binding material, or may be a soy protein dough obtained by kneading water or oils and fats using powdered soy protein as a binding raw material. Which dough is prepared can be appropriately selected by those skilled in the art depending on the amount of livestock used.
In this dough, the oriented textured soy protein of a specific shape used in the present invention is mixed, but the oriented textured soy protein is usually a dried body, so that for the reasons described above, an appropriate amount of water is absorbed, The tissue is softened (referred to as “water reconstitution”) and then mixed into the dough. Furthermore, if necessary, the above-described non-oriented textured soybean protein and other raw materials can be added.
Next, after preparing these materials by kneading these raw materials as follows, the dough is formed into a desired shape and subjected to heat treatment.

(Kneading / Molding)
The raw material is uniformly kneaded with a kneader such as a silent cutter. Further, a dough is prepared by adding sub-materials such as hydrated oriented textured soy protein and, if necessary, non-oriented fibrous textured soy protein, to obtain a molded product formed into a desired size and shape with a molding machine. . This is then subjected to a heating step. In addition, the oriented textured soy protein is kneaded at the stage of obtaining the dough, so that the tissue is usually present in a state where the tissue is unwound and dispersed. Therefore, the specific shape and size in the dry state are not maintained at the final product stage.

(Heating process)
As the heating means in the present invention, firing heating, steaming heating, boil heating, fly heating, electromagnetic wave heating and the like can be used in appropriate combination. As a result, the formed dough is heated and solidified, and the shape is stabilized.

  The product obtained as described above can be provided in the form of processed meat products such as banburg and meatballs.

  Hereinafter, the embodiment of the present invention will be described more specifically by way of examples. Unless otherwise specified, “%” and “part” mean “% by weight” and “part by weight”.

(material)
The oriented textured soy protein used was obtained as follows. That is, with reference to Example 1 of Patent Document 6 (Japanese Patent Laid-Open No. 2000-279099), 55 parts of separated soybean protein “New Fuji Pro E” (protein content 92%, Fuji Oil Co., Ltd.), defatted soybean (Protein content 53%) 25 parts and 20 parts of wheat starch are mixed, and 100 parts of this mixed raw material is mixed with calcium sulfate in an amount corresponding to 1% of calcium, and 40 parts of water is a biaxial extruder. After being extruded into a rod shape from a die by heating and reacting under the conditions of a screw rotation speed of 200 rpm, a barrel inlet side temperature of 80 ° C., a central portion of 120 ° C., an outlet side of 150 ° C., and a flow rate of 30 kg / hour. Rotating blade type continuous cutter (commitment) installed at the exit of the biaxial extruder so that the major axis is 10-20 mm and the minor axis is 5-8 mm. It was cut with Lumpur), which was then dried (orientation textured soybean protein (1)) was used.
Separately, a slit-shaped die was used and extruded in a flat shape under the same conditions as described above, and then cut with a cutter so that the major axis was about 40 to 60 mm and dried. The oriented textured soybean protein (2) thus obtained had a thickness of about 5 mm and a minor axis of about 20 mm.
As the non-oriented textured soy protein, “New Fujinic” (manufactured by Fuji Oil Co., Ltd., approximately 2 mm long diameter × 2 mm short diameter × 2 mm thick type) was used. As the isolated soybean protein, “New Fuji Pro” (produced by Fuji Oil Co., Ltd.) was used.

(Example 1) Meatball-like food (meatless)
First, 9 parts of water was added to 3 parts of oriented textured soy protein (1) to perform water reconstitution. At this time, the time required for rehydration was about 30 minutes, and the working efficiency was very good.
Next, 6 parts of separated soy protein as powdered soy protein, 2 parts of dried egg white, 4 parts of rapeseed oil as liquid oil, 9 parts of water, and 3 parts of oriented tissue-like soy protein rehydrated as described above (water 9 parts) was put into a silent cutter, kneaded at about 25 ° C., and uniformly emulsified to prepare a soybean protein dough.
After adding 13 parts of water to 9 parts of non-oriented textured soy protein and rehydrating, add 23 parts of onion, 14 parts of seasoning, 8 parts of solid vegetable oil and fat, and 3 parts of starch, and mix to make the dough. Obtained. The dough was molded into a 28 mm diameter sphere (25 g) with a molding machine. This was followed by steaming (85-95 ° C.) for 8 minutes, air cooling, and quick freezing at −35 ° C. to obtain meatball-like foods that did not use livestock meat (Test 1 in Table 1). Next, as shown in Tests 2 to 4 in Table 1, meatball-like foods were similarly obtained by changing the amount of oriented textured soybean protein in various ways. About the foodstuff of the tests 1-4 obtained by the above, the fiber feeling of livestock meat was evaluated.
The results are shown in Table 1.

(Table 1) Recipe and quality evaluation results

In Test 1, although it is a meatless food that does not use any livestock meat, it feels the fiber of the meat in addition to the graininess of the minced meat and has a texture that is not inferior to the meatballs of livestock meat. It was. On the other hand, in Comparative Test 1 in which the oriented textured soybean protein was not blended, although there was a feeling of flesh, no feeling of fiber was felt at all, and it was an artificial texture with a rough feeling. Although the fiber feeling becomes stronger as the tests 2 and 3 are more mixed than the test 1, the fiber feeling is slightly too strong in the test 3, and conversely, the hardness tends to be weakened.
In addition, a meatball-like food was prepared using the oriented textured soy protein (2) instead of the oriented textured soy protein (1) in the same composition as in Test 1, and the meatball-like food of Test 1 was prepared. As a result of comparison of the fiber feeling, a stronger fiber feeling was obtained when the oriented textured soybean protein (2) having a larger major axis was used, and the hardness was not as hard as Test 2.

(Example 2)
As shown in Table 2, a meatball-like food was prepared in the same manner as in Test 1 of Example 1 except that the amount of non-oriented textured soybean protein was changed and the amount of water was adjusted.

(Table 2) Recipe

  In any case, the texture was good in that it had a fiber feeling. Among them, Test 4 in which non-oriented textured soy protein was not added was a texture with a poor texture. On the other hand, the grain feeling tended to increase as Test 5 and Test 6 with a large amount added, but in Test 6, the grain feeling was too strong and the texture was somewhat lacking.

(Example 3)
As shown in Table 3, the amount of dried egg white was changed, and the meatball-like food was adjusted in the same manner as in Test 1 of Example 1.

(Table 3) Recipe

  In any case, the texture was good in that it had a fiber feeling. Among them, in Test 7 in which dry egg white was not added, the hardness was slightly weakened, and in Test 8, there was a tendency to become harder than in Test 7, but the texture was weaker than in Test 1. In Test 9, the texture was too hard.

(Comparative Example 1)
As a comparison of the oriented textured soy protein used in the examples, an eyebrow-shaped oriented textured soy protein having a major axis of 4 cm, a minor axis of 2 cm, and a thickness of about 2 cm was used. Got food.
The quality of the obtained meatball-like food was the same as in Test 1. However, even when 9 parts of water was added to 3 parts of oriented textured soy protein in the tank, it was difficult for water to be absorbed uniformly. Therefore, when the oriented textured soy protein was added to excess water, the protein floated. It was necessary to squeeze this overnight with a gravel and squeeze excess water so that the protein: water ratio was 1: 3 after soaking. As described above, the use of an orientated textured soy protein in the form of eyebrows was very poor in production efficiency.

(Comparative Example 2)
As a comparison of the oriented textured soy protein used in the examples, a granular oriented textured soy protein having a major axis of 5 mm, a minor axis of 5 mm, and a thickness of about 5 mm was used. Got.
The hydrated soy protein used could be rehydrated efficiently as in Test 1. However, the obtained meatball-like food was lacking in fiber feeling compared to Test 1 because of the short fiber length.
From the above, it was suggested that the major axis is required to be at least about 10 mm in order to impart a fiber feeling.

(Example 4) meatless ham Powdered soy protein material 4 parts of separated soy protein, 9 parts of rapeseed oil as liquid oil, 19 parts of water were put into a silent cutter and kneaded at about 25 ° C., uniformly Emulsified.
Next, 12 parts of oriented textured soy protein (1) was reconstituted with 36 parts of water by mixing with a mixer, followed by mixing 5 parts of dried egg white, 3 parts of starch, and seasoning. A dough was obtained.
The dough was filled in a casing, steamed and heated (at 85 ° C. for 60 minutes), air-cooled, and then frozen at −20 ° C. to obtain meatless ham dough.
The food was cut into a ham-like thickness with a slicer in a half-thawed state to make meatless ham.
For comparison, non-oriented textured soy protein was used instead of oriented textured soy protein (Comparative Example 1). Table 4 shows the formulation and results.

(Table 4)

  As described above, in Example 4 using oriented textured soy protein, the physical fiber feeling was imparted and good, but in Comparative Example 2 using non-oriented soy protein, the grain feel was imparted. The quality without fiber feeling.

(Example 5) In a nugget mixer used in combination with chicken, 2 parts of separated soy protein, 19 parts of water, and 58 parts of chicken fillet (φ about 10 to 20 mm) were mixed, and the oriented textured soy protein (1) 4 A part of which was returned with 12 parts of water was added, and 3 parts of seasoning and 2 parts of starch were added to obtain 100 parts of nugget dough. The dough was formed into a nugget with a weight of 15 g by a molding machine, and then steamed and heated (85 ° C. for 10 minutes), and air-cooled. Next, dusting and battering were performed, fried (175 ° C. for 3 minutes), air-cooled, and rapidly frozen.
In the comparative example, non-oriented textured soybean protein was used instead of oriented textured soybean protein. Table 5 shows the composition of the inner material and the results.

(Table 5)

  As described above, Example 5 using oriented textured soy protein gave good feeling of physical fiber, but Comparative Example 4 using non-oriented textured soy protein gave feeling of grain. However, the quality did not feel fiber.
