Embodiment 1

[0024] A kind of preparation method of dietary fiber of black soybean hulls, the steps are:

[0025] (1) Selection: remove the black beans and impurities mixed in the black bean skin;

[0026] (2) Crushing: crush the selected black soybean skin, and collect the black soybean skin powder that has passed through a 40-mesh sieve;

[0027] (3) Soaking: Mix black soybean hull powder with 5.76% molar HCl-ethanol solution according to the ratio of 1:10 to soak for 80 hours;

[0028] (4) Adjust PH value: adjust the soaked solution to neutral with NaOH solution;

[0029] (5) Filtration: filter the neutral solution, and wash the filter residue twice with 95% ethanol with a solid-to-liquid ratio of 1:10;

Abstract

The invention discloses a preparation method of black soybean hull dietary fiber and belongs to the technical field of food processing. The preparation method includes: (1), removing black soybeans and impurities in black soybean hull; (2), smashing the black soybean hull which is selected and clean, and collecting black soybean hull powder passing a 40-mesh screen; (3), mixing the black soybean powder with an HCl-alcohol solution according to a material-liquid ratio of 1:10 for soaking for 65-80 h; (4), using a NaOH solution to adjust the solution after soaking to neutral; (5), filtering the neutral solution, and using 95% alcohol of a material-liquid ratio of 1:10 to flush filter residue twice; (6), disposing the filter residue after being washed in an oven of 60 DEG C for drying to obtain the black soybean hull dietary fiber. In the preparation method, the black soybean hull is used as a raw material for the first time and the HCl-alcohol solution is used for soaking modification of the black soybean hull powder, so that content of soluble dietary fiber in the black soybean hull is increased to improve nutritional value of the black soybean hull.

Description

technical field [0001] The invention belongs to the technical field of food processing, and relates to a method for preparing dietary fiber from black soybean hulls. Background technique [0002] Black beans are the black seeds of the leguminous plant soybean. Black beans have the characteristics of high protein and low calorie, with black skin and yellow or green inside. Black bean skin is called "material bean coat" in traditional Chinese medicine, which has the effect of detoxification and diuresis. Chinese medicine has always believed that black beans are the valley of the kidney, enter the kidney, and have the functions of invigorating the spleen and diuresis, reducing swelling and lowering qi, blackening hair and prolonging life. Modern pharmacological studies have confirmed that black soybeans not only contain rich protein, lecithin, fat and vitamins, but also contain melanin and niacin. Because of this, black beans have always been regarded as a good product for bo...
