Method for producing high purity nanometer grain dietary fiber

Abstract

A process for preparing high-purity edible nano-fiber from grains includes such steps as extracting in diluted alkali solution to remove protein, high-temp alpha-amylase enzymolyzing for deactivating enzyme and removing odor smell, superfine wet pulverizing, ultrahigh-pressure dynamic nano-class homogenizing and spray drying.

Description

Production method of high-purity nano grain dietary fiber technical field The invention relates to a production method of high-purity nano grain dietary fiber. Background technique The production method of nano grain dietary fiber has not been reported so far. There are many kinds about the production method of cereal dietary fiber, but existing production method has following shortcoming: 1, the production method of traditional dietary fiber has used a large amount of strong acid and strong alkali, as Zhang Yankun etc. " research on preparation technology of soybean dietary fiber The "preparation method of soybean dietary fiber" invented by Han Jun and others used a large amount of hydrochloric acid and sodium hydroxide. The use of strong acid and strong alkali will reduce the water holding capacity of dietary fiber and also reduce the functional effect of dietary fiber; 2. Traditional The surface effect, interface effect and small size effect of the dietary fiber produc...

There are many kinds about the production method of cereal dietary fiber, but existing production method has following shortcoming: 1, the production method of traditional dietary fiber has used a large amount of strong acid and strong alkali, as Zhang Yankun etc. " research on preparation technology of soybean dietary fiber The "preparation method of soybean dietary fiber" invented by Han Jun and others used a large amount of hydrochloric acid and sodium hydroxide. The use of strong acid and strong alkali will reduce the water holding capacity of dietary fiber and also reduce the functional effect of dietary fiber; 2. Traditional The surface effect, interface effect and small size effect of the dietary fiber produced by the dietary fiber production method are not obvious, the effective contact surface with the intestinal tract is small, and the absorption rate and utilization rate are low; functional effects, such as preventing arteriosclerosis, The efficacy of coronary heart disease and the prevention and treatment of diabetes cannot be fully exerted; 3. The dietary fiber produced by the traditional dietary fiber production method has large particles, most of which are between 40 and 60 mesh, with rough taste, low absorption rate and utilization rate
