In recent years, the eating habits of Japanese people have rapidly improved and we are entering an age of satiation, but when looking at the protein intake, the intake of animal protein is higher than that of vegetable protein, and the accompanying harmful effects of fat intake are becoming more prevalent in adults. It has become a factor in illness. For this reason, traditional Japanese food has been reconsidered as nutritionally extremely well-balanced, and it has become a hot topic not only in Japan but also in the United States. On the other hand, cooking in Japanese households is becoming more and more labor-saving year by year, and dishes are progressing toward dishes that can be eaten as is or by simple preparation. Against this background, the inventor has conducted many years of research into processed products of tofu, which is one of the excellent vegetable proteins, and has developed a method for producing high-quality, highly pure protein that is delicious and easy to prepare. They succeeded in making processed fried tofu frozen tofu as a food product. The present invention will be described in detail below. Soaked soybeans are crushed and steamed to elute proteins and other components and remove fibers. Coagulants such as calcium chloride, magnesium chloride, calcium sulfate, and glucono delta-lactone are added to the resulting soymilk to make tofu. , and press this to a moisture content of 75-85%. The moisture content of this tofu can be adjusted depending on the desired softness of the product, but up to this point, conventional tofu making techniques are used as is. Next, use a cutter mixer to add seasonings and quality improvers such as starch to the pressed and cooled tofu, grind it into a paste, and add toppings such as vegetables, seaweed, meat, etc., either as is or pretreated according to your preference. After selecting and mixing, the mixture is filled into a container of an appropriate size or type and heated to solidify. The heating method is generally steam, but hot air or hot water may also be used. Maintain a core temperature of 80°C to 90°C for about 15 minutes. As shown in the table below, if the temperature is below 79°C, it will not bind sufficiently, and if it is above 91°C, it will pass through.

[Table] After heating and solidifying, open the container and cut into appropriate sizes (preferably about 10 mm to 20 mm thick).
After frying in vegetable oil at 180℃~190℃ and cooling in the refrigerator,
Freeze below -2℃. This freezing point decreases as the water content decreases or by adding quality improvers such as seasonings and starch. In the case of frozen tofu, it is frozen at -10°C to -15°C and then left at -2°C to -3°C for 2 to 3 weeks to freeze-denature the protein and create a sponge tissue.
(Hereinafter, aging refers to leaving once-frozen tofu in the freezer to cause freeze denaturation.) Freezing and aging produce ice crystals inside the tofu, which enlarge and become concentrated. Protein denaturation progresses, and when ice thaws, ice crystals melt and cavities are formed, forming a tissue. A longer aging period will produce a firmer structure, while a shorter aging period will produce a softer structure. When frozen and aged at a relatively high temperature of -2°C to -9°C, the ice crystals become large and the structure becomes rough even after dehydration; at around -10°C to -19°C, the structure is slightly It becomes finer. At around -20℃ to -29℃, the structure becomes even finer, and when frozen and aged below -30℃, the structure becomes very fine, and after thawing, the structure becomes close to the state before freezing, making it edible. The feeling is also close to life. The progress of freeze-denaturation of proteins is fastest at -2°C to -5°C and becomes slower as the temperature decreases. The temperature and time of freezing and ripening can be adjusted appropriately depending on the desired tissue. The progress of freeze denaturation can be determined by an increase in tissue firmness measured by a texturometer or a decrease in solubility in alkaline solutions. In the present invention, as mentioned above, once the tofu is ground, seasonings and various ingredients can be mixed in, and by mixing the seasonings and ingredients, it is possible to create various tastes as a food product. . By frying this heated and coagulated product in oil, it becomes a product that is easier to handle, and in terms of taste, frying brings out the aroma inherent in soybeans, making it a more delicious product. This product is further left in the freezer to ripen and undergo freeze denaturation, and by selecting various degrees of freeze denaturation, the product can have the desired texture, improve the taste, and improve the taste when used in boiled dishes etc. The product absorbs the broth very well and does not fall apart when cooked. In this way, the present invention improves the structure of seasoned and fried tofu by freezing and aging it at an appropriate temperature, improving the taste and texture, and making it into a highly nutritious plant-based tofu that is easy to handle and cook. It exhibits the excellent feature of providing processed deep-fried frozen tofu as a protein food. The present invention will be explained in more detail with reference to Examples below. Example 1 Firm tofu is made by adding a coagulant to soy milk in the usual manner. The moisture content of this tofu should be approximately 80%. 90kg of tofu cooled in a water tank and 3770g of seasonings (sugar
1,600 g, 500 g of salt, 1,400 g of soy sauce, 180 g of bonito extract, 90 g of sodium glutamate) were ground and mixed in a high-speed cutter for about 10 minutes to form a paste, and 200 g of roasted sesame seeds and 5,000 g of seasoned carrots were ground.
Add 1800g of shiitake mushrooms and 900g of kelp and mix evenly. After mixing, fill it into a mold box and heat it to a center temperature of 84°C to 88°C in a steamer.
Maintain the temperature at ℃ for 15 minutes to solidify by heating. After solidifying, open the mold and cut into 16mm cubes, then fry in vegetable oil at 180℃ to 190℃. After cooling to about +2℃~+3℃ in the refrigerator, -
Place in the freezer at 20℃ and leave to ripen for 24 hours. When you take it out of the freezer and thaw it, you can make processed fried tofu. You can eat it as is, or when you boil it, it won't fall apart and absorbs the broth very well.
Moreover, it is soft and has extremely good taste and texture. Example 2 Firm tofu is made by adding a coagulant to soy milk in the usual manner. The moisture content of this tofu should be approximately 78%. 90kg of tofu cooled in a water tank and 3950g of seasonings (sugar
Grind and mix 1400g of salt, 600g of salt, 1400g of soy sauce, 450g of beef extract, and 100g of sodium glutamate in a high-speed cutter for about 10 minutes to form a paste, fill it into a mold box, and heat it to a center temperature of 86℃ to 88℃ in a steamer.
Maintain for 15 minutes to heat and solidify. After solidifying, it is opened from the mold, cut into strips 20mm thick, and fried in vegetable oil at 180℃ to 190℃. Cool it in the refrigerator to about +2℃~+3℃, then put it in the -10℃ freezer to freeze and leave it for 16 hours to ripen. When you take it out of the freezer and thaw it, you can make processed fried tofu. As in Example 1, it is easy to handle as it is or in boiled dishes, is soft, and has extremely good taste and texture.
