Japanese Patent Publication No. 60-10893 Japanese Patent Publication No. 3-11750

  An object of the present invention is to provide a method for producing a meat-like dried protein processed food having meat-like flavor and texture as ingredients for instant food.

The inventors tried to develop a dry ingredient having a meat-like texture and flavor as a substitute for meat as an ingredient for instant food. However, by simply seasoning and drying the textured protein material produced by extruding by extruding and extruding plant protein as a main ingredient, which is usually used as a main ingredient, in terms of flavor and texture, Was far away. In addition, although a seasoned tissue-like protein material tried to frying by the edible oils and fats, is prior to returning hot water, but the smell, such as soybean smell is decreased, when the return hot water hot water return is poor, Tsu fat It was too savory.

Therefore we result of intensive studies, after seasoning process textured protein material made porous, after adjusting the amount of edible oil, by heating and drying by hot air, by contracting the protein The present inventors have found that a meat-like dried protein processed food excellent in meat-like flavor and texture can be provided when the porous structure is controlled and reconstituted with hot water.

  That is, the textured protein material produced by extrusion into a block or flat sheet using an extruder is rehydrated, dehydrated, and the obtained textured protein material is seasoned, and then edible fats and oils Is added so that the fat content after drying becomes 10 to 20% by weight, and dried with hot air at 100 to 120 ° C. so that the water content becomes 5 to 12% by weight. It is a manufacturing method.

  Moreover, it is preferable that the temperature of the hot air in this invention is 105-115 degreeC.

  Moreover, it is preferable to add the amount of edible fats and oils in this invention so that the fats and oils content after drying may be 12 to 16 weight%.

  The present invention can provide a method for producing a meat-like dried protein processed food having meat-like flavor and texture as ingredients for instant food.

  Hereinafter, the present invention will be described in detail. However, the present invention is not limited to the following description.

1. Preparation of textured protein material The textured protein material according to the present invention is prepared by kneading plant-derived powder material such as defatted soybean powder, soybean protein powder, wheat protein powder and starch with water, and using a twin screw extruder at high temperature and high pressure. It is made by being extruded through a die under normal pressure. At this time, the textured protein material has a porous structure by being released at once from high pressure to normal pressure. In addition, by changing the shape of the die, a massive or sheet-like tissue protein material can be obtained. The obtained textured protein material may be used as it is, but can be stored for a long time by drying or freezing.

  The prepared textured protein material is immersed in water and rehydrated. There is no particular limitation on the water reconstitution method, but by immersing it in water for about one night, the whole tissue-like protein material spreads moisture, resulting in a moderately elastic tissue. Next, the rehydrated tissue protein material is dehydrated to remove unnecessary moisture. By dehydrating, not only can unnecessary components be removed, but also odors such as soybean odor and wheat protein odor can be reduced.

2. Textured protein material processing step In the present invention, although it is not always necessary to perform this step, the textured protein material can be formed by pressing the dehydrated textured protein material with a roll or a cutting blade roll or by forming a kerf. Since the material has elasticity and fiber orientation, it has a more meaty texture. In addition, through this process, not only does the seasoning liquid and edible oil and fat easily penetrate into the entire textured protein material when seasoning processing described later and edible oil and fat are added, but also the restorability at the time of eating Get better.

When the textured protein material is crushed by a roll or a cutting blade roll or provided with a kerf, it is preferably passed through the roll or cutting blade roll in the same direction as the textured protein material extruded by the biaxial extruder. . Passing through a roll or cutting blade roll in a direction perpendicular to the extruded direction is not preferable because the directionality of the fiber is destroyed.

3. Seasoning process Next, the textured protein material is seasoned. The raw material used for the seasoning process may be changed according to the intended instant food, and is not particularly limited. For example, salt, mirin, sake, sugar, reducing sugar, soy sauce, sodium glutamate, protein hydrolyzate, nucleic acid, meat extract, juice or powder of onions and ginger, spices, pigments, fragrances, antioxidants, etc. What is necessary is just to perform a seasoning process by immersing a tissue-like protein raw material in the seasoning liquid which mixes directly with a proteinaceous raw material or melt | dissolved.

  The method for immersing in the seasoning liquid is not particularly limited, and the immersion may be performed only by immersing in the seasoning liquid or while heating or heating. The textured protein material immersed in the seasoning liquid is drained to remove unnecessary seasoning liquid and used in the next step.

4). Add edible fat to the textured protein material seasoned with edible fat. The edible oil / fat to be added is not particularly limited, but a liquid oil having a melting point of 20 ° C. or higher, preferably a semi-solid of 30 ° C. to 50 ° C. or so as not to elute the edible oil / fat from the meat-like dried protein processed food produced during storage. It is preferable to use solid oil. Examples of such edible fats and oils include palm oil, cacao oil, lard, and beef tallow. Moreover, when melting | fusing point of edible fats and oils is too high, the flavor of the oil at the time of eating will be bad, and a touch will also worsen. When semi-solid or solid oil is used, it is melted to form a liquid and then added to the tissue protein material.

  The amount of edible oil / fat added depends on the moisture content of the textured protein material before the addition of edible oil / fat, so it should be added to 10-20% by weight with respect to the weight of the dried meat-like dried protein processed food. Is preferred. If it is less than 10% by weight, it will be subjected to the flavor of meat-like oil, the restorability will be improved and the texture will be soft. On the other hand, if it exceeds 20% by weight, it not only has an oily flavor but also has poor restorability and a hard texture. More preferably, it is 12 to 16% by weight.

  The method for adding edible fats and oils is not particularly limited, and may be directly sprayed on the seasoned tissue protein material, or may be added by mixing with a mixer or the like. Edible fats and oils may be added with an oil can, but deoiling treatment is required. In addition, when the temperature of the edible fat increases, the textured protein material surface is hardened or the porous structure of the textured protein material is strengthened.

5. Heat drying and then drying the textured protein material to which oils and fats have been added with hot air at 100 to 120 ° C. until the water content becomes 5 to 12% by weight. By drying with high-temperature hot air, the porous structure is controlled and dried while shrinking the protein, resulting in a meat-like tactile sensation with an appropriate elasticity at the time of eating, resulting in a cooked flavor. When the temperature is lower than 100 ° C., the porous structure is weakly contracted, the restorability is too good, and the texture is soft and lacks elasticity, and the cooked flavor is lacking. Moreover, when it exceeds 120 degreeC, since a part of textured protein raw material will generate | occur | produce during drying, it is unpreferable. More preferably, it is 105-115 degreeC.

Moreover, since the water | moisture content after heat drying becomes higher than 12 weight%, since a preservability is missing, it is not preferable. When the content is less than 5% by weight, the textured protein material becomes hard, and the textured protein material breaks during storage or transportation. More preferably, it is 6 to 10% by weight.

6). In addition, the dried textured protein material can be used as an ingredient for instant foods as a meat-like dried protein processed food through sieving and a foreign matter sorting process.

As described above, the textured protein material made porous made by being extruded pressurized and heated back water in an extruder, was dehydrated, subjected to seasoning treatment, after the addition of oil, 100 to It can be heated and dried with hot air at 120 ° C to shrink the protein and control the porous structure, so that the restorability can be controlled, and the meat-like flavor and texture are excellent when reconstituted in hot water. A dried protein processed product can be provided.
