preparation example Construction

[0041] A kind of preparation method of bean flour, comprises the following steps:

[0042] Deactivate the enzymes of raw soybeans, after coarse grinding and fine grinding, and solid-liquid separation, sterilize and deodorize the obtained soybean milk, add auxiliary materials after cooling down, homogenize, sterilize, concentrate, spray dry, cool, and sieve powder , to obtain the bean flour.

[0043] Whole soybeans do not contain beany smell. The beany smell is due to the catalysis of lipoxygenase during the crushing process, and the polyene fatty acids in soybean oil are oxidized into fatty acid hydroperoxides. The substance is very unstable, and once formed, it will quickly decompose to produce some low-molecular compounds such as aldehydes, alcohols, and ketones. Among them, acetaldehyde is the main component that causes beany smell, and linoleic acid and linolenic acid can also produce obvious beany smell. Therefore, the inactivation of lipoxygenase is to eliminate the be...

Abstract

The present invention provides soybean powder and a preparation method thereof. The soybean powder comprises the following steps: raw material soybeans are subjected to enzyme inactivation; the treated soybeans are subjected to coarse grinding and fine grinding; after solid-liquid separation, obtained soybean milk is sterilized and deodorized; after cooling, accessory materials are added; and after homogenizing, sterilization, concentration, spray drying, cooling and sieving are conducted to obtain the soybean powder. The provided preparation method of the soybean powder solves problems that soybean milk cannot be drunk at any time; and preparation processes are complicated. The preparation method effectively removes beany flavor of the soybeans and does not damage the nutrients of the soybean milk. The soybean powder dissolves quickly and can be drunk at any time. The provided soybean powder is reasonable in nutrition matching, fragrant and mellow in taste and relatively high in nutritional value.

Description

technical field [0001] The invention relates to the technical field of food, in particular to a bean flour and a preparation method thereof. Background technique [0002] Soymilk is made by soaking soybeans in water, grinding them, filtering them, and boiling them. Soy milk is very nutritious and easy to digest and absorb. Different from Western milk, soy milk is a food with Chinese national characteristics. Soymilk is a favorite drink of the Chinese people and a nutritious food suitable for all ages. It enjoys the reputation of "plant milk" in Europe and the United States. Soy milk is rich in vegetable protein and phospholipids, as well as vitamin B1.B2 and niacin. In addition, soy milk also contains minerals such as iron and calcium, especially the calcium contained in it, which is very suitable for various groups of people, including the elderly, adults, teenagers, children and so on. [0003] Fresh soy milk can be drunk in all seasons. Drinking soy milk in spring an...
