Problems solved by technology

[0002] The production method of cereal, fruit dietary fiber has multiple, and there is following shortcoming in existing production method: 1, the production of traditional dietary fiber has used a large amount of strong acid and strong alkali and chemical reagent, as " the soybean dietary fiber of invention such as Han Jun "Preparation method" uses a large amount 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 also reduce the functional effect of dietary fiber; 2. Traditionally produced dietary fiber has low water-soluble dietary fiber, According to research, water-soluble dietary f...

Abstract

The invention relates to a production method for water soluble dietary fiber, which adopts lactic acid and citric acid treatment to replace traditional strong acid and strong alkali treatment, applies hyperpressure homogenizing treatment to replace traditional processing treatment, separates the water soluble dietary fiber by centrifugal separation, and finally obtains final products by sponging drying. The method has the advantages that: 1. weak acids such as the lactic acid and the citric acid are utilized to carry out modification treatment to the dietary fiber; 2. high-temperature stewing is utilized to decompose or evaporate unpleasant odor in raw material to cause the odor of the products to be easily accepted by consumers; 3. the water soluble dietary fiber is separated out by the centrifugal separation on the basis of weak acids, high-temperature stewing and hyperpressure homogenization and finally dried to be powder by the sponging drying; 4. the production technique method of the method is simple and the industrialization is easy to realize.

Description

technical field [0001] The invention relates to a production method of water-soluble dietary fiber, in particular to a production method of water-soluble grain, fruit and vegetable dietary fiber. Background technique [0002] The production method of cereal, fruit dietary fiber has multiple, and there is following shortcoming in existing production method: 1, the production of traditional dietary fiber has used a large amount of strong acid and strong alkali and chemical reagent, as " the soybean dietary fiber of invention such as Han Jun "Preparation method" uses a large amount 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 also reduce the functional effect of dietary fiber; 2. Traditionally produced dietary fiber has low water-soluble dietary fiber, According to research, water-soluble dietary fiber has played an important role when bringing into play the fun...
