The invention relates to the technical field of bean products, and discloses medicated tofu curded by sour
slurry and a preparation method thereof. The medicated food bean curd is prepared by using black beans, water and medicated
food components (including Chinese wolfberry fruit
powder, red date
powder,
astragalus membranaceus
powder,
angelica sinensis powder and
cistanche deserticola powder) in a specific proportion as raw materials and using purely-fermented sour
slurry as a coagulator. The preparation method mainly comprises the steps of
raw material pretreatment, cooked pulp preparation, pulp boiling and fusion, sour pulp
curdling,
compression molding and the like. The invention aims to solve the technical problems that in the prior art, a chemical coagulator is used, so that the bean curd is rough in texture and heavy in beany
flavor, medicated
food components are non-uniformly dispersed, and
active components are easy to lose. According to the medicated food bean curd and the preparation method thereof disclosed by the invention, the sour
slurry preparation and the slurry
cooking process are combined, and the
raw material ratio is optimized, so that the prepared medicated food bean curd is fine and smooth in texture, good in elasticity, mellow in
flavor, free of beany
flavor, uniform in medicated
food component distribution and high in functional component
retention rate, and is mainly used as a food with
nutrition and health-care functions. Derivative varieties such as cold bean curds and high-
protein bean curds can be prepared through modular adjustment.
