Abstract

The invention discloses a method for extracting multifunctional dietary fiber from wheat bran. Raw bran is first screened to remove impurities, and the starch is repeatedly washed with water. The bran is stirred and washed with water at a temperature of 5-40°C and a liquid-solid ratio of 5:1-10:1 for 10-30 minutes. Filter to get the filter residue, add 5 to 10 times of water, stir and wash for 10 to 30 minutes, and filter; acid treatment to remove phytic acid, take water to wash the bran, adjust the pH value of the control system to 3.5 to 5 with dilute acid, and the temperature to 35 to 65°C , the liquid-solid ratio is 9:1-14:1, stirring and washing for 15-60 minutes, stopping adding acid and stirring for 15-60 minutes; filtering, neutralizing, washing, drying and pulverizing to obtain a dietary fiber product with high protein content. The invention solves the problems of low phytic acid removal rate, complex production process, long time consumption and low benefit when extracting multifunctional dietary fiber from wheat bran.

Description

technical field [0001] The invention relates to a method for extracting multifunctional dietary fiber from wheat bran. Background technique [0002] The main component of wheat bran dietary fiber is insoluble dietary fiber, which is rich in content, close to 40%. It is widely used in the fields of noodle products, meat, health products, etc., and has the characteristics of outstanding water holding capacity, low energy, strong adsorption capacity, and bifidobacteria proliferation. Because of its safety and reliability, it has been used in the food industry for a long time. Because of its poor taste, it may affect the utilization of minerals by the human body, and its application range is always limited. Contents of the invention [0003] The technical problem to be solved by this invention is: for the defect that above-mentioned prior art exists, a kind of production process is simple, the method for extracting multifunctional dietary fiber from wheat bran that phytic ac...
