Embodiment 1

[0021] The production process of the activated wheat bran dietary fiber provided by the present embodiment comprises the following steps:

[0022] (1) Cleaning: Wash the wheat bran with water for 3 times, then dry it to remove impurities such as floating dust in the raw bran, and pre-dry it until the water content is 30%.

[0023] (2) Fractionation and separation by breaking the wall: The protein and starch adhering to the surface of the bran are effectively peeled off by physical wall breaking machine, and the peeled protein and starch are separated through the fractionation and separation system by using the different specific gravity, so that The crude fiber content is increased, and the crude fiber content reaches 60%.

[0024] (3) Enzymolysis: Enzymolyze the crude fiber obtained by fractionation, add 12 parts by weight of monoglyceride stearate and 15 parts by weight of malic acid to 100 parts by weight of the crude fiber, and add 0.2 parts of For high temperature resist...

Embodiment 2

[0032] The production process of the activated wheat bran dietary fiber provided by the present embodiment comprises the following steps:

[0033] (1) Cleaning: Wash the wheat bran once with clean water, then dry it to remove impurities such as floating dust in the raw bran, and pre-dry it until the water content is 30%.

[0034] (2) Fractionation and separation by breaking the wall: The protein and starch adhering to the surface of the bran are effectively peeled off by physical wall breaking machine, and the peeled protein and starch are separated through the fractionation and separation system by using the different specific gravity, so that The crude fiber content is increased, and the crude fiber content reaches 60%.

[0035] (3) Enzymolysis: Enzymolyze the crude fiber obtained by fractionation, add 8 parts by weight of monoglyceride stearate and 10 parts by weight of malic acid to 100 parts by weight of the crude fiber, and add 0.01 part of For high temperature resistan...

Embodiment 3

[0043] The production process of the activated wheat bran dietary fiber provided by the present embodiment comprises the following steps:

[0044] (1) Cleaning: Wash the wheat bran twice with water, then dry it to remove impurities such as floating dust in the raw bran, and pre-dry it until the water content is 30%.

[0045] (2) Fractionation and separation by breaking the wall: The protein and starch adhering to the surface of the bran are effectively peeled off by breaking the wall with a physical wall breaking machine, and the peeled protein and starch are separated by using the different specific gravity through the fractionation system to obtain Crude fiber, the content of crude fiber reaches 60%.

[0046] (3) Enzymolysis: Enzymolyze the crude fiber obtained by fractionation, add 10 parts by weight of monoglyceride stearate and 12 parts by weight of malic acid to 100 parts by weight of crude fiber, and add 0.1 part of For high temperature resistant α-amylase, add water t...

Abstract

The invention discloses a process for producing activated wheat bran dietary fibers. The process comprises a step (1) of cleaning, a step (2) of wall breaking and fractionation, a step (3) of enzymolysis, a step (4) of high temperature enzyme deactivation and concentration, a step (5) of low temperature vacuum continuous drying and a step (6) of smashing. According to the method, wheat bran is pre-cleaned and predried and then coarse dietary fibers in the wheat bran are extracted through a physical wall breaking and fractionation technology, and the method belongs to physical separation technologies. According to the method, not only is the fiber content improved, but also active substances in bran are not chemically damaged, the naturality of the active substances is maintained. After enzymolysis of the extracted crude fibers, not only is the taste improved, but also the content of active polysaccharide xylooligosaccharide is also improved to 10% or above. The activated wheat bran dietary fibers are prepared through superfine grinding, water absorption capability and swelling capacity of the activated wheat bran dietary fibers are improved, and the product application effect is improved. Full ingredients of the bran are effectively utilized, the comprehensive utilization rate of the raw materials is improved, and the environmental pollution problem is also solved.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of activated wheat bran dietary fiber. Background technique [0002] Dietary fiber is a general term for polysaccharide carbohydrates and lignin that are not digested by the human body. It is usually divided into two categories: insoluble dietary fiber and water-soluble dietary fiber. Water-insoluble dietary fiber includes cellulose, hemicellulose, and lignin, which exist in plant cell walls, and water-soluble cellulose includes pectin, β-glucan, and oligosaccharides. Dietary fiber has the characteristics of water absorption and adhesion, so it has a series of physiological functions such as preventing constipation, helping weight loss, preventing colon and rectal cancer, preventing hemorrhoids, lowering blood lipids, preventing coronary heart disease, and improving symptoms of diabetes. Therefore, it is known as the human body. The seven...
