Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the following examples further describe the present invention in detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] In this technology, two kinds of microorganisms are used for fermentation, Actinomucor elegans and Propionibacterium freudenreichii, among which the fungus Actinomucor elegans is often used in the fermentation process of fermented bean curd, which can metabolize starch or polysaccharides It is a simple sugar and cannot produce vitamin B12 when used alone. The bacterium Propionibacterium frescheri is often used in the fermentation of Swiss cheese. Fermentation in milk can produce a small amount of vitamin B12, but it is not found in the fermentation of plant materials alone. Ability to produce vitamin B12. In the technical scheme of the present...

Abstract

The invention relates to a method for generating vitamin B12 by using vegetarian materials. The method comprises the following steps: inoculating a strain of an edible fermentation fungus capable of metabolizing starch or polysaccharide into monosaccharide to a surface of a coagulum of a soybean mixture; culturing by fermentation under aerobic conditions at room temperature until hyphae overgrow; inoculating a strain of Propionibacterium freudenreichii to the surface of the coagulum of the soybean mixture; and culturing by fermentation under low-oxygen and room temperature conditions until vitamin B12 is generated. The vitamin B12 is prepared by fermenting a plurality of microbe strains in the purely vegetarian materials, and the method can be used for producing purely vegetarian and natural food containing the vitamin B12 for long-time vegetarians due to religious faiths or fashion trends.

Description

technical field [0001] The present invention relates to a method for producing vitamin B12, and more particularly, to a method for producing vitamin B12 using vegetarian materials. Background technique [0002] Vitamin B12 is very important to the health of the human body. A lack of proper amount of vitamin B12 will lead to pernicious anemia and damage to the brain nerves. Because vitamin B12 mainly exists in meat and milk, not in plants, it is not edible for some Long-term vegetarians of dairy foods will cause malnutrition, which has always been a problem in nutrition. Although it is said that vitamin B12 exists in soybeans recently, experimental evidence and Western research do not agree with this statement, but the fact is due to plant All kinds of food itself is absolutely lack of vitamin B12, and some foods often add vitamin B12 in it. The current production of vitamin B12 is through microbial fermentation technology, which converts precursor chemicals into vitamin B12...
