Abstract

The invention relates to a nanometer dietary fiber product, takes the wheat bran or malt or rice bran as raw materials and comprises biological enzymatical hydrolysis, concentration, spraying or freeze-drying. According to the weight percentages, the product contains non-aqueous dietary fiber 55%-65%, water-soluble dietary fiber of fiber peptide 30%-40%, and balancing water, wherein, the fiber peptide accounts for 10%-20% of the total amount of water-soluble dietary fiber. The invention carries out the biological enzymatical hydrolysis to raw materials through neutral proteinase, which can carry on hydrolysis to macromolecular proteins in the raw materials to be further divided into micro-molecule peptide and effectively convert the utilization of proteins, and facilitates digestion and absorption of bodies. The original minerals such as B clan vitamin, selenium, and magnesium and the like in the raw materials lead the spillage of extremely rich micronutrients such as vitamin E and B clan vitamin to be substantially enhanced, and the absorbed rate is achieved to correspondingly increase.

Description

technical field [0001] The invention relates to a nano-dietary fiber product and its preparation method and application. Background technique [0002] Wheat bran and malt are the non-staple foods of flour, while rice bran is the non-staple food of rice. It contains B vitamins, selenium, magnesium and other minerals, and also contains a lot of dietary fiber. According to modern medical research, dietary fiber is indispensable for a healthy diet, and fiber plays a necessary role in maintaining a healthy digestive system. Wheat bran, malt and rice bran contain a large amount of natural dietary fiber. Using its insoluble fiber swelling effect, it can promote defecation and relieve constipation symptoms, inhibit the growth of saprophytic bacteria that are prone to carcinogens in the colon, block the production of carcinogens, and prevent intestinal It has a good effect on reducing blood cholesterol, hyperlipidemia, hyperglycemia, hypertension, coronary heart disease, etc. At pr...
