Embodiment 1

[0016] A preparation method of natto bacteria powder, the specific operation process is: select plump soybeans and corn without mold, then wash the soybeans and corn, dry them after cleaning, mix the soybeans and corn after drying, and It is pulverized, and the mass ratio of corn and soybeans is 2:7; liquid fermentation is carried out, and soybeans and corn powder are put into a fermenter, and then fermented water is added to the fermenter, and then heated and left to ferment. The fermentation time is 3 hours, the fermentation temperature is 40°C during the liquid fermentation process, and the pH is controlled at 6.8-7.2; then the inoculation is carried out using Bacillus natto as the provenance, the inoculation amount is 5%, and the static fermentation is carried out after the inoculation. The fermentation time is 23 hours, and the nattokinase in the fermentation liquid is activated; the fermentation liquid is centrifuged, and the separation liquid is taken out after separatio...

Abstract

The invention provides a preparing method for bacillus natto powder. The method comprises the specific operation procedures that full and mildew-free soybeans and corn are selected, cleaned, dried, mixed and smashed; liquid fermenting is carried out, soybean powder and corn powder are placed into a fermenting tank, fermentation material water is added into the fermenting tank, then warming and standing fermenting are carried out, and fermenting time is 2-4 hours; then inoculation is carried out, bacillus natto is utilized as a strain source to carry out inoculation, the inoculation amount is 2-8%, after inoculating is carried out, standing fermenting is carried out, and fermenting time is 20-24 hours. According to the method, a separator is utilized for acting on the fermenting liquor, solid and liquid in the fermenting liquor can be separated more thoroughly, and smoothness of later-period operation of production is ensured, finally, the concentrated liquid is frozen in a vacuum mode, invasion of bacteria in the freezing process is avoided, purity of nattokinase powder is ensured, and quality of the nattokinase powder is ensured.

Description

technical field [0001] The invention relates to the field of biological technology related to the use of liquid pure-bred fermentation in food engineering, in particular to a preparation method of natto bacteria powder. Background technique [0002] Nattokinase powder is Bacillus Natto Fermented soybeans, purified powder products. Research has found that nattokinase can dissolve thrombus, lower blood pressure, lower blood fat, lower blood sugar, relieve alcohol and protect the liver, and improve intestinal function Laxative, detoxification and beauty and other effects, so nattokinase powder is widely used by people. In order to meet people's demand for nattokinase powder, people further study the production of nattokinase powder. The production of existing nattokinase powder is relatively complicated, mainly using soybeans for processing and extraction, but this method is complicated to operate and wastes time for extraction. , and contains various impurities inside, whi...
