Problems solved by technology

Yet the protein content ratio in the bean curd that this invention makes is low, is only about 35%, and the mouthfeel of tofu is soft, not brittle, and secondly this invention directly adds soybean dietary fiber in formula, does not process soybean dietary fiber and There is no constraint on the particle size of soybean dietary fiber, which directly affects the taste and texture of tofu

Abstract

The invention relates to high-protein bean curd with a smooth, tender and crisp taste and a preparation method of the bean curd. The method comprises the following steps: (1) grinding low temperatureedible soya bean meal to form low temperature edible soya bean meal powder, mixing with water for extra high pressure treatment to form slurry, (2) mixing, grinding and adding soy isolate protein andthe water into soybean oil for regrinding, (3) adding the slurry obtained in step (1) into a mixture obtained in step (2), and performing grinding, filling, refrigeration, cooking and cooling in the presence of a cross-linking agent to form the bean curd. The prepared bean curd is good in color, is not red, has a high protein content, and is smooth, tender and crisp in taste.

Description

technical field [0001] The invention relates to high-protein, smooth, tender and crispy tofu and a preparation method thereof, belonging to the technical field of food processing. Background technique [0002] The birth of tofu has completely changed the fate of soybeans. Tofu makes it easier for the human body to absorb and utilize soybean protein; tofu is high in protein, low in fat, and has the effects of lowering blood pressure, blood fat, and cholesterol. It can be used raw or cooked , suitable for all ages, good food for health preservation, longevity and longevity. Traditional tofu is made from soybeans through processes such as soaking, refining, boiling, marinating, molding, and pressing. Traditional tofu takes a long time to process, has low production efficiency, consumes a lot of water, and produces wastewater and waste residues that pollute the environment. Moreover, tofu has low protein content and is fragile, which is not conducive to processing, storage and ...
