Problems solved by technology

[0003] At present, there is almost no fermented soy milk on the market. The main limiting factors are the fishy and astringent taste of the bean itself, the sour taste during the fermentation process, and the rough texture after fermentation, etc., which make the public accept it relatively low.
In order to overcome the defects, the astringent and rancid taste of fermented soy milk is mainly covered by adding milk, fruit juice, flavor, etc.; at the same time, some anti-nutritional factors of the bean itself, such as trypsin inhibitors, limit the application of soy milk
How to control the bad flavor in the fermentation process of soybean milk production and reduce the bad factors at the same time, still haven't found a good solution in terms of production technology

Abstract

The invention provides a preparation method of fermented soybean milk and relates to the technical field of food fermentation. The preparation method primarily comprises (1), cleaning soybeans, peeling, degerminating and soaking; (2), processing through a jet cavitation machine, separating milk from bean dregs, and flashing; (3), extracting soybean milk, adding stabilizers into the soybean milk and dissolving, blending, homogenizing, sterilizing and cooling; (4), fermenting. The fermented soybean milk is fermented based on full vegetation without any bean flavor, bitter taste or other bad smell, has smooth taste, thick fermented fragrance, rich nutrition, low production cost and good flavor, and is free of animal origins in production.

Description

technical field [0001] The invention relates to the technical field of food fermentation, in particular to a method for preparing fermented soybean milk. Background technique [0002] Soy milk is a high-quality vegetable protein beverage with soybeans as the main raw material. Because it contains protein, unsaturated fatty acids and major vitamins that are easily absorbed by the human body, and it is rich in mineral salts and does not contain cholesterol, it is widely welcomed by the public. With the continuous improvement of the public's demand for healthy consumption, protein drinks fermented with plant sources and probiotics are becoming more and more popular among the public. [0003] At present, there is almost no fermented soy milk on the market. The main limiting factors are the fishy and astringent taste of the bean itself, the sour taste during the fermentation process, and the rough texture after fermentation, etc., which make the public accept it relatively low. ...
