The spicy strips in the market at present have various tastes, and in addition to the traditional spicy and hot taste and the sweet and spicy taste, new tastes such as beef taste and barbecue taste gradually appear. The spicy strips contain various additives and preservatives, have low nutritional value, and can cause anorexia and abdominal distension and discomfort when being eaten too much. In addition, some products have high hardness, poor toughness and poor chewing mouthfeel. The leisure food produced by the extrusion method has the characteristics of diversified functions, high production efficiency and the like, and is widely applied to the field of food. The nutritional requirements of vegetarians can be met, and the risks of diseases such as hypertension and obesity can be effectively reduced. The extrusion processing efficiency is high, the cost is low, no chemical pollution exists, and the product after extrusion processing has the characteristics of high digestibility, less nutrient loss, long shelf life and the like. The protein from different sources has certain difference in physicochemical property and nutritional value, animal and plant proteins are subjected to compound extrusion, and the products obtained by extrusion after mutual mixing not only have improved nutritional value, but also have better appearance, flavor and texture characteristics, and have good embodiment on nutritional balance.
The soybean protein isolate has reasonable amino acid proportion and rich nutrition, contains lysine which is deficient with most cereal proteins, has unique functional characteristics, is a high-quality protein source, and can improve the nutritional value of food when being added into the food, so the soybean protein isolate has wide application in the food. Can be used as additive to be added into food to regulate the protein ratio in food and improve the utilization rate of protein; the protein-rich meat product is added into meat products, under the condition of not influencing the mouthfeel of the meat, the protein content in the meat products is increased, the defects of high calorie, low vitamin and the like of animal meat are overcome, the texture of the meat products is improved by utilizing the functional characteristics of the protein, the water retention and fat retention capacity of the meat products is improved, and the flavor is improved. When added into flour products, the additive can improve the quality of the flour products, improve the color, the fragrance and the taste of food, and also effectively improve the shelf life of the food.

Using Zhao Jiang [1] Etc. to determine amino acid scores, biovalencies; the sensory evaluation indexes are shown in Table 4.
TABLE 1
TABLE 2
TABLE 3
As can be seen from Table 1, the flavor composite protein spicy strip snack food disclosed by the invention is aromatic in flavor, compact in structure and uniform in texture, has a unique bean flavor of the product, has a bulky and porous structure after rehydration, has the rehydration rate of not less than 200%, has the hardness of 420.20-454.66 g, the elasticity of 0.977-0.983 and the chewiness of 362.02-399.32, and is good in hardness and elasticity and good in chewing taste. The obtained product has the characteristic of high protein, the protein content is not lower than 60g/100g, and the product meets the high protein standard in GB28050-2011 national Standard for food safety, pre-packaged food Nutrition Label general rules. The instant leisure food with different flavors can be prepared after simple seasoning, and is healthy and delicious, and the processing technology is simple. As can be seen from Table 2, the essential amino acids of the products of examples 1 to 3 were all higher than the FAO/WHO pattern standard when evaluated based on the FAO/WHO equilibrium pattern of essential amino acids. The soybean protein isolate powder and the egg white powder are used as main raw materials, the nutritive values of plant protein and animal protein can be integrated, the variety of necessary amino acid is complete, and people can obtain multiple nutritive values in one food. As can be seen from Table 3, the bio-value is an index reflecting the degree of utilization of the protein in the food by the body after digestion and absorption, and the higher the bio-value of the products of examples 1 to 3 is, the higher the utilization rate of the protein by the body is, and the higher the nutritional value of the protein is.
TABLE 4
TABLE 5
Comparative example 1 is different from example 1 in that the amount of the soy protein isolate powder added is different from that of the egg white powder added. The addition of the egg white powder can improve the problems of poor texture and chewing feeling of a single soybean protein isolate extruded textured product, and is superior to the extrusion effect of the single soybean protein isolate. Comparative example 2 differs from example 1 in the moisture content. The extrusion process is lack of moisture, lack of viscosity, can not be fully melted, and the product can not be expanded, so the hardness is higher. Too much hardness affects the chewiness of the product, which is high and has poor mouthfeel. Comparative example 3 differs from example 1 in the barrel temperature. At lower temperatures, the material is not completely cured and does not meet the requirement of forming a stable texture in the extruded product. Comparative example 4 differs from example 1 in the screw rotation speed. When the rotating speed of the screw is low, the detention time of the materials in the extruder is prolonged, so that part of the materials are burnt, and the product contains hard blocks during extrusion, so that the hardness and the chewiness are high, and the quality is poor. Therefore, after the soy protein isolate powder and the egg white powder are compounded, the extruded product not only has the characteristic of high protein, but also can solve the problems of poor texture and chewing feeling of a single soy protein isolate extruded textured product by adding the egg white powder, has better extrusion effect than the single soy protein isolate and has better sensory quality. In addition, under the condition of the optimal technological parameter combination, the composite protein extruded leisure food with better quality can be obtained.
TABLE 6
Comparative example 5 is different from example 2 in that the amount of the soy protein isolate powder added is different from that of the egg white powder added. The addition of the egg white powder can improve the problem that the texture and the chewing feeling of a single soybean protein isolate extruded textured product are poor, and when the addition amount of the egg white powder is increased, the elasticity of the product is increased, the mouthfeel is improved, and the extrusion effect of the egg white powder is better than that of the single soybean protein isolate. Comparative example 6 differs from example 2 in the moisture content. Excessive water can reduce the temperature in the extruder, so that the viscosity of the raw material is reduced sharply, the extrusion and shearing of the material by the screw are not facilitated, the retention time of the raw material in the extruder is reduced, the product puffing effect is poor, and the sensory score is reduced correspondingly. Comparative example 7 differs from example 2 in the barrel temperature. As the barrel temperature increases, the water inside the product evaporates more and more intensely, and thus the hardness of the product increases. Comparative example 8 differs from example 2 in the screw rotation speed. However, when the rotation speed of the screw is too high, the mixing and heating time of the raw materials in the extruder is greatly shortened, and undenatured protein forms a hard core in the extruded product, so that the hardness and chewiness of the product are high, and the quality of the product is poor.
In conclusion, the method has a synergistic effect among the soybean protein isolate powder, the egg white powder, the raw material water content regulation, the barrel temperature and the screw rotation speed, and the soybean protein isolate powder, the egg white powder, the raw material water content regulation, the barrel temperature and the screw rotation speed are better than the effect of changing one condition when used together.
Although the embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit and scope of the invention and the appended claims, and therefore the scope of the invention is not limited to the embodiments disclosed.
