Soy protein isolate vegetarian hot dogs and preparation method thereof

Abstract

The invention relates to the fields of foods and food processing, in particular to soy protein isolate vegetarian hot dogs and a preparation method thereof. The soy protein isolate vegetarian hot dogsare prepared from the raw materials of soy protein isolate, vegetable oil, starch, spice, transglutaminase and water and are prepared through the technologies of performing hydrating, performing emulsifying, performing mixing, performing filling, performing putting, performing drying, performing packing, performing sterilization and the like. According to the method, special gel properties and emulsifying properties of the soy protein isolate are sufficiently used, and a drying method is used for replacing a conventional steaming method, so that the elasticity, the tenacity and the crispnessof products can be notably improved. The soy protein isolate vegetarian hot dogs being high in nutrition and good in mouth feel are produced, and besides, the problem that when being cooked, conventional vegetarian hot dogs are easy to explode can be effectively solved. The technology is quite simple and easy to popularize and apply.

Description

technical field [0001] The invention relates to the field of food and food processing, in particular to a soybean protein isolate vegetarian sausage and a preparation method thereof. Background technique [0002] Vegetarian sausage is a vegetarian sausage food made of beans as the main raw material, which is often used as a raw material for further cooking and processing. Most of the existing vegetarian sausage products use textured soybean protein made by extrusion as the main raw material. Because the protein content in textured soybean protein is low, only about 60%, and its unique network structure reduces the extension of the product. properties, making the vegetarian sausage prepared with it as the main raw material have poor elasticity, toughness, and poor taste, which can no longer meet the needs of most consumers, seriously affecting and hindering the development of the vegetarian sausage industry. [0003] Soybean Protein Isolate (SPI) is a full-price protein food...

Problems solved by technology

[0004] At present, although there are also soybean protein isolates added to the raw materials of some vegetarian sausage products, for example, the invention patent "soybean vegetarian sausage and its manufacturing method" (CN 991034740) discloses a kind of soybean curd base, protein isolate, ginger, green onion, Soybean vegetarian sausage made from salt, sugar, spiced perfume, edible oil, soda flour, red yeast rice powder, monosodium glutamate and soy sauce; a patent application "a method for making simulated vegetarian sausage" (CN201610966962.1) discloses a A kind of simulated vegetarian sausage made of soybean textured protein, soybean protein isolate, soybean oil and water as main raw materials, made of vegetarian fat meat, mixed with vegetarian meat, mixed with proportioned ingredients, enema-molded, steamed and smoked; patent application " A vegetarian sausage containing dietary fiber and its processing technology" (CN201610080388.X) discloses a vegetarian sausage containing dietary fiber, which uses soybean tissue protein, soybean protein isolate, and wet bean dregs as the main raw materials, and is soaked and dehydrated , chopping, stirring, sausage enema, cooking, coolant packaging and other more than a dozen processes; the patent application "a soybean protein sausage and its preparation method" (CN2015108277464) discloses a soy protein isolate, tissue Soybean protein vegetarian sausage made of protein, vegetable oil, starch, salt, sugar, monosodium glutamate, spices, vegetarian flavor, potassium sorbate, TG enzyme and red yeast rice; It still contains a large amount of soybean texture protein, so that the performance and taste of the product cannot be improved in essence
