Problems solved by technology

[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 lowerin

Embodiment 1

[0033] The present invention is a method for preparing peptide-containing dietary fiber powder, which includes the following steps:

[0034] Step one, fiber raw material pretreatment: the fiber raw material used in this embodiment is soybean meal. The fiber raw material pretreatment process is a combination of impurity cleaning, immersion treatment and then freezing treatment. Impurity cleaning is to remove foreign materials from the fiber material. , Washing, including removing the husk and inner seed coat; soaking treatment is to remove impurities and clean the fiber raw materials, according to the dry weight of the fiber raw materials and the weight ratio of water 1: 3-5 add water, soak at a temperature of 4 ℃ for 16 hours 、Soak for 10 hours at a temperature of 10℃ or 4 hours at a temperature of 30℃, add 0.1%-0.5% baking soda by weight of the fiber material in the soaking water; the freezing process is to freeze the fiber material after the soaking process to The fiber materia...

Embodiment 2

[0045] The present invention is a method for preparing peptide-containing dietary fiber powder, which includes the following steps:

[0046] Step one, fiber raw material pretreatment: the fiber raw material used in this embodiment is bean dregs. The fiber raw material pretreatment process is a combination of impurity cleaning, high-temperature cooking and then freezing treatment. The impurity cleaning is to remove the impurity of the fiber raw material. Material, cleaning, including removing the husk and inner seed coat; high-temperature cooking is to steam the cleaned fiber material at a temperature of 110°C for 50 minutes, at a temperature of 120°C for 30 minutes or at a temperature of 130°C Down steaming for 10 minutes is beneficial to inactivate harmful factors and remove the smell of soybeans; freezing treatment is to freeze the fiber material after high-temperature steaming until the fiber material is completely frozen. The freezing condition is freezing at -20°C for 8 hours...

Embodiment 3

[0060] The present invention is a method for preparing peptide-containing dietary fiber powder, which includes the following steps:

[0061] Step one, fiber material pretreatment: the fiber material used in this embodiment is Wheat bran, The pretreatment process of fiber raw materials is a combination of impurity cleaning, baking treatment, and freezing treatment after soaking. The impurity cleaning is to remove foreign impurities and cleaning the fiber raw materials, including removing the husk and inner seed coat; Baking treatment is to bake the cleaned fiber material at 160℃ for 30 minutes, at 180℃ for 25 minutes, or at 200℃ for 20 minutes; soaking treatment is to remove impurities after cleaning For fiber raw materials, add water according to the ratio of dry weight of fiber raw materials to water weight of 1:4, soak for 16 hours at a temperature of 4℃, and add 0.3% of the weight of the fiber raw materials in the soaking water; baking soda; freezing treatment is to soak The l...

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...
