Embodiment 1

[0024] Get 200 grams of dried corn husks, grind and sieve with a FW177 type Chinese medicine pulverizer (produced by Tianjin Taylor Instrument Co., Ltd.), add 800 grams of cornstarch and mix evenly, add an appropriate amount of water, and measure the moisture content with a grain moisture meter. 18% will do. Pour the prepared raw material powder into the feeding hopper of the twin-screw extrusion extruder, turn on the power, set the extruding temperature to 180°C, control the rotation speed of the twin-screw to 500 rpm, and the screw speed of the feeding hopper to 600 rpm, and then carry out Extruded puffed.

[0025] Use the FW177 type Chinese medicine pulverizer (produced by Tianjin Teluste Instrument Co., Ltd.) to pulverize the raw material after puffing, put it in the enzymolysis tank, add 10 liters of water, adjust the pH value of the feed solution to 7.0 with sodium hydroxide or hydrochloric acid solution, and use YJ501 type super thermostat (produced by Shanghai Suopu I...

Embodiment 2

[0028] Take 300 grams of dry corn husks, crush and sieve, add 700 grams of corn starch and mix evenly, add an appropriate amount of water, measure the water content to 15% with a grain moisture meter, and pour the prepared raw material powder into a twin-screw extrusion extruder In the feeding hopper, turn on the power, set the puffing temperature to 150°C, control the twin-screw rotation speed to 450 rpm, and the feeding hopper screw speed to 500 rpm, and then perform extrusion and puffing.

[0029] Crush the puffed raw material, put it into the enzymolysis tank, add 10 liters of water, use sodium hydroxide or hydrochloric acid solution to adjust the pH value of the feed solution to 7.0, use a super constant temperature water bath to control the enzymolysis temperature at 95°C, and add 0.15 liters of water while stirring. % high-temperature-α-amylase, stirred for 30 minutes. Then, adjust the pH value of the feed solution to 3.0 with hydrochloric acid solution, control the enz...

Abstract

The invention provides a production method of a high active corn bran dietary fiber and the product thereof, and belongs to the technology field of the agricultural product deep processing. The invention comprises that the corn bran raw material is mixed with the corn starch by proportion of 1:4 after being pulverized, and extrusion pressing and puffing are performed; enzymolysis is performed with high temperature-alpha-amylase, next, the high active corn bran dietary fiber is prepared through the enzymolysis with acid protease, through the centrifugal filtration, is molded by drying below 75 DEG C, and then the light yellow corn bran dietary fiber is produced. The invention technology can improve the microstructure and the composition of the corn bran dietary fiber, and the dissoluble dietary fiber content is improved by 10 to 40 percent; the component of starch as well as protein in the dietary fiber can be removed by using the technology of enzymatic hydrolysis, and the dietary fiber content can be up to 90 percent. The product corn bran dietary fiber with high purity and high activity meets the needs of the general consumers to the pure natural and high active dietary fiber food, and thereby, the product corn bran dietary fiber has a broad market development prospect.

Description

1. Technical field [0001] The invention relates to a production method of high-activity corn bran dietary fiber and a product thereof, belonging to the technical field of deep processing of agricultural products. 2. Technical background [0002] Before the 1970s, nutritionists believed that crude fiber was a non-nutritive ingredient that had no nutritional effect on the human body. With the in-depth research and development of nutrition and medicine, especially in the late 1970s, people found that this "non-nutrient" is closely related to human health, and it plays an important role in preventing certain diseases of the human body. The term "crude fiber" was gradually replaced by "dietary fiber". Denis Burkitt and Hugh Trowell and others proposed that coarse grains or foods rich in dietary fiber can prevent some diseases that occur in Western societies such as bowel cancer, diverticular disease, appendicitis, constipation, hemorrhoids, diabetes, heart disease, high choleste...
