Making method of black bean/premna microphylla leaf pectin type Suanjiang tofu based on high-pressure homogenizing treatment

Abstract

The invention provides a making method of black bean / premna microphylla leaf pectin type Suanjiang tofu based on high-pressure homogenizing treatment. The making method comprises the following steps of adding black beans with black skin and yellow kernels into water, performing soaking, taking out the soaked black beans, filtering the obtained black bean soaking water, performing cooking to achieve a boiling state, and performing bacterium reduction for standby application; adding northeast soybeans into water, performing soaking, taking out the soaked northeast soybeans, adding the taken-outnortheast soybeans and the black beans with black skin and yellow kernels into the black bean soaking water together, and performing grinding to obtain soybean milk; then adding a premna microphylla leaf pectin solution and a natural preservative, sequentially performing treatment in an ordinary homogenizing machine and a super-high pressure homogenizing machine, immediately adding water for reducing the temperature to 63-67 DEG C so as to obtain cooked soybean milk, performing pulp solidification with lactic acids, and continuing performing protein coagulation so as to obtain jellied bean curd blocks; and reversing a curtain in the direction of a cross for 3-4 times so that jellied bean curds are solidified for the second time and are polymerized together to form the jellied bean curd blocks, putting the water-broken jellied bean curds in a basin completely, performing loading into a cloth wrapping frame, and in a self-pressing manner, after blank wrapping is completed, reversing a plate for self-pressing so as to obtain the black bean / premna microphylla leaf pectin type Suanjiang tofu based on high-pressure homogenizing treatment.

Description

technical field [0001] The invention belongs to the technical field of bean product materials, and in particular relates to a method for preparing black bean / leaf pectin-type Physalis bean curd based on high-pressure homogeneous treatment. Background technique [0002] Tofu, also known as Fuli, was first invented and created by my country, and now it occupies a very important position in people's daily diet. The performance of tofu has a lot to do with raw materials, preparation technology and storage. Traditional tofu processing mainly includes raw material pretreatment, soaking, beating or grinding, boiling, filtering, coagulation, pressing and dehydration, etc. etc. affect tofu processing and its quality. [0003] Soybean is the main raw material of traditional tofu. Soybean protein has the ideal amino acid composition required by the human body, and soybean contains isoflavones, daidzein and other functional active substances, which can reduce blood lipids and promote h...
