Preparing method of peptide-containing dietary fiber powder and prepared peptide-containing dietary fiber powder

Abstract

The invention relates to a preparing method of peptide-containing dietary fiber powder and the prepared peptide-containing dietary fiber powder. The preparing method comprises the steps of pretreatment of fiber raw materials; superfine pulping through a thermal method; enzyme hydrolysis, wherein superfine fiber pulp obtained after superfine pulping through the thermal method in step 2 is subjectedto protease hydrolysis or compound enzyme hydrolysis, polypeptides and small-molecule peptides are generated in the superfine fiber pulp after the superfine fiber pulp is subjected to enzyme hydrolysis, and then peptide-containing fiber pulp is prepared. According to the preparing method, the process steps are simple, the production cost is low, no bean dregs are discharged, soybean fibers are all utilized, and sufficient utilization of full-soybean resources is facilitated; meanwhile, environmental pollution can be avoided, and promotion of traditional bean product industries is facilitated.

Description

Technical field [0001] The invention relates to the field of processing of agricultural products, in particular to a method for preparing peptide-containing dietary fiber powder and the peptide-containing dietary fiber powder prepared by the method. Background technique [0002] Soybean is one of the four major oil crops in my country. It is rich in protein, unsaturated fatty acids and B vitamins. It is also an important source of high-quality protein and high-quality dietary fiber in the diet of Chinese residents. Due to the unhealthy diet and living habits that have brought many chronic diseases to modern people, people urgently need to adjust their dietary consumption structure. Soy protein is an internationally recognized high-quality protein. The future prospects are bright. The development of the soybean industry in our country will always be related to the national economy and people’s livelihood. Big thing. [0003] Focusing on the development of all soybeans and the utili...

[0006] Wheat bran and rice bran are the main by-products of grain processing. They are rich in nutrients and dietary fiber. The average protein content of wheat bran is about 15.8%, and the average protein content of rice bran is about 15%. At present, wheat bran and rice bran are not fully utilized. caused a huge waste

[0007] Peptides and small molecular peptides have biological activities such as lowering blood pressure and lipids. Peptides currently on the market have many process steps, high cost, and expensive prices. The daily consumption is generally recommended to be less than 10 grams. Most of the terminal soybean peptide products are mainly small-dose granules or compounded and diluted, resulting in expensive soybean peptide terminal products, limited beneficiary groups, and cannot be popularized.
