Abstract

The present invention relates to the technical field of seasoning products and particularly discloses a preparation method of fermented bean curd powder. The preparation method comprises the followingsteps: A) pre-fermentation is conducted: an expandedly cultured actinomucor elegans As3.2778 strain is sprayed on a fermentation plate; soybean bases cooled to room temperature are placed on the fermentation plate; the expandedly cultured actinomucor elegans As3.2778 strain is evenly sprayed on the upper surfaces of the soybean bases; and fermentation is conducted at a temperature condition of 15-20 DEG C for 3-5 days to obtain mold bases; B) a small amount of edible salt and baijiu are added in the mold bases; and an inoculation of aroma-producing yeasts is conducted for post-fermentation; at the same time, seasoning materials are added; and the fermentation is conducted for 4-5 days to obtain mature fermented bean curd rich in fragrances and flavoring materials; and C) the fermented bean curd sauce is vacuum freeze-dried; and after the drying, the fermented bean curd is put into an ultrafine crushing machine to be crushed to obtain flavored fermented bean curd powder rich in edibleactive mucor, active yeasts and lactic acid bacteria. The soybean bases in the preparation technology of the fermented bean curd powder are subjected to the twice multi-micro-organism fermentation before and after. The prepared fermented bean curd powder is rich in taste, mellow in mouthfeel, short in preparation cycle, less in infectious micro-organisms and long in shelf life.

Description

technical field [0001] The invention relates to the technical field of condiments, in particular to a preparation method of fermented bean curd powder. Background technique [0002] Fermented bean curd is rich in nutrients, with a protein content of 15-20%. It contains a large amount of amino acids and peptides. Microorganisms synthesize vitamin B12, which is not found in general plant foods. Vegetarians often eat fermented bean curd to prevent pernicious anemia. The content of vitamin B group in fermented bean curd is very rich. Regular consumption can supplement vitamin B12 and prevent senile dementia; therefore, it can increase appetite and help digestion; because microorganisms decompose phytic acid in beans, the original absorption rate of soybeans is very low. Low iron, zinc and other minerals are more easily absorbed by the body. Sufu also contains minerals such as calcium and phosphorus. [0003] Fermented bean curd is not only a good tableware, but also a good sea...
