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" has used d-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

Embodiment 1

[0012] Embodiment one, be raw material with bean dregs, its processing step is:

[0013] 1. Preparation of working starter: (1) Strain activation: ① Preparation of basal medium: make skim milk powder into a milk solution, and add 1% sucrose. ②: Packing: Pack the prepared medium in To be inoculated in the Erlenmeyer flask, and plugged with a cotton stopper. ③Sterilization: Sterilize at 0.1Pa for 15 minutes. Then let it drop to normal pressure naturally, cool down, and wait for inoculation. ④ Inoculation: After the medium is cooled to about 40°C, insert solid (or liquid) lactic acid bacteria (including Streptococcus lactis, Streptococcus thermophilus, Streptococcus casei, Lactobacillus acidophilus, Bacillus bulgaricus, Lactobacillus into the medium) , Lactobacillus helveticus), insert 0.01% lactic acid bacteria according to the weight ratio; 5. culture: put the inoculated test tube into a constant temperature incubator for fermentation, the fermentation temperature is 40°C, and...

Embodiment 2

[0016] Embodiment two, take corn dregs as raw material, and its processing step is:

[0017] 1. Preparation of working starter: (1) Strain activation: ① Preparation of basal medium: make skim milk powder into a milk solution, and add 1% sucrose; ②: Subpackage: Subpackage the prepared medium in Put it in a triangular flask to be inoculated, and plug it with a cotton plug; ⑧ Sterilization: Sterilize at 0.1 Pa for 15 minutes. Then let it naturally reduce the pressure to normal pressure, cool down, and wait for inoculation. ④ Inoculation: After the medium is cooled to about 40°C, insert solid (or liquid) lactic acid bacteria (including Streptococcus lactis, Streptococcus thermophilus, Streptococcus casei, Lactobacillus acidophilus, Bacillus bulgaricus, Lactobacillus into the medium) , Lactobacillus helveticus), insert 0.01% lactic acid bacteria according to the weight ratio; 5. culture: put the inoculated test tube into a constant temperature incubator for fermentation, the fermen...

Abstract

The invention discloses a method for improving cereal dietary fiber solubility. The method utilizes lactobacillus fermentation treatment to replace traditional acid-alkali treatment, utilizes superhigh-pressure homogenization treatment to replace traditional processing treatment and finally prepares the finished product by spray drying. The method has the advantages that 1, lactic acid is produced by lactobacillus fermentation and dietary fibers are modified by the simulative chemical treatment method so that a dietary fiber structure is loose and the loose dietary fiber structure is conducive to follow-up processes; and the method has mild treatment conditions so that a water-binding capacity and functions of the dietary fibers are kept well; 2, a fragrance of metabolites such as lactic acid produced by lactobacillus fermentation covers a bad smell of raw materials such as bean dregs so that the fragrance of the product can be easily accepted by consumers; 3, the dietary fiber production method comprises the superhigh-pressure homogenization treatment based on fermentation treatment so that the particle size of the dietary fibers is reduced to less than 40 micrometers and roughness of the dietary fibers is not felt by consumers; and 4, the method has simple processes and can be industrialized easily.
