Abstract

A preparing method of low-sensitization fermented yoghurt soymilk is disclosed. The preparing method includes following steps of: (1) preparing soymilk by a conventional technology; (2) adjusting the temperature of the soymilk in the step (1) to 37-50 DEG C, adjusting the pH value to be 6.0-8.0, adding transglutaminase into the soymilk according to a ratio of 100-1600 U / L, adding 4-8% of cane sugar, stirring uniformly and maintaining the temperature for 0.5-2 h; (3) preparing lactobacillus rhamnosus, lactobacillus bulgaricus, lactobacillus bifides and lactobacillus plantarum according to a mass ratio of 1:1:2:2 into a mixed fermentation agent, adding the mixed fermentation agent into the soymilk in the step (2) that is pre-adjusted to 37-43 DEG C according to a massic volume ratio of 3-6%, mixing uniformly, and maintaining the temperature and fermenting for 4-9 h; and (4) refrigerating the fermented soymilk obtained in the step (3) and cooking to obtain the low-sensitization fermented yoghurt soymilk. The preparing method is high in plasticity, easy to control, safe and economical. A product of the method is low in sensitization, rich and comprehensive in nutrition, stable in characteristics, uniform in quality and proper in taste.

Description

technical field [0001] The invention belongs to the field of food biotechnology. Background technique [0002] Soybean contains about 40% protein, and its amino acid ratio is close to the best amino acid absorption ratio of human body. It is one of the main sources of high-quality protein; at the same time, soybean is also rich in dietary fiber, unsaturated fatty acids, vitamins, minerals and natural antioxidants. Cancer ingredients—soy isoflavones and other nutrients have high nutritional value. In recent years, with the continuous exposure of the safety issues of milk and its products, as well as the improvement of people's living standards and the enhancement of health awareness, soybean milk has become increasingly popular among consumers as a healthy vegetable protein drink. However, like milk, eggs, fish and shrimp, aquatic shellfish, wheat, peanuts, and tree nuts, soybeans are also one of the eight categories of allergic foods identified by the Food and Agriculture O...
