Method for producing cereal diet fiber of high soluble diet fiber content

Abstract

The production process of cereal diet fiber with high soluble diet fiber content has lactic acid bacteria fermentation to replace traditional acid and alkali treatment, ultra high pressure homogenization to replace traditional processing and final spray drying to obtain ultimate product. The present invention features the lactic acid bacteria fermentation capable of loosening diet fiber and favorable to subsequent processing and maintaining the water binding capacity and function of diet fiber, the high pressure homogenization on the basis of fermentation to reduce the granularity of diet fiber to below 40 micron and to eliminate the roughness feeling of diet fiber, and simple production process easy to use in industrial production.

Description

Technical field [0001] The invention relates to a method for producing cereal dietary fiber with high soluble dietary fiber content. Background technique [0002] There are many methods for producing grain dietary fiber. The existing production methods have the following shortcomings: 1. The production of traditional dietary fiber uses a large amount of strong acids and alkalis and chemical reagents, such as the "Preparation Method of Soybean Dietary Fiber" invented by Han Jun et al. "Using a lot of hydrochloric acid, sodium hydroxide and hydrogen peroxide, the use of strong acids and alkalis will reduce the water holding capacity of dietary fiber and also reduce the functional effect of dietary fiber; 2. Traditionally produced dietary fiber has low soluble dietary fiber, according to research. Soluble dietary fiber plays an important role in exerting the function of dietary fiber. Dietary fiber with low soluble dietary fiber content has little function; 3....

Problems solved by technology

[0002] The production method of cereal dietary fiber has multiple, and existing production method has following shortcoming: 1, the production of traditional dietary fiber has used a large amount of strong acid and strong alkali and chemical reagent, as " the preparation method of soybean dietary fiber of invention such as Han Jun "Using a lot of hydrochloric acid, sodium hydroxide and hydrogen peroxide, the use of strong acid and strong alkali will reduce the water holding capacity of dietary fiber, and will also reduce the functional effect of dietary fiber; 2. Traditionally produced dietary fiber has low soluble dietary fiber, according to research. Soluble dietary fiber plays an important role in the function of dietary fiber. Dietary fiber with low content of soluble dietary fiber has little function; The method for obtaining soluble dietary fiber" uses α-amylase, protease, xylanase and cellulase, and the cost of using the enzyme method to produce dietary fiber is high, and the process is complicated and difficult to realize industrialization; 4. The production method of existing dietary fiber The dietary fiber particles produced are large, mostly between 60 and 80 mesh, and the taste is rough
