Embodiment

[0037] Taking specific wheat processing by-products as an example, the inventor specifically introduces the fermentation process for preparing postbiotics from wheat processing by-products designed in this application as follows.

[0038] (1) Prepare materials

[0039] In terms of mass ratio, wheat starch processing water and wheat bran were mixed uniformly at a ratio of 5:1, heated at 121°C for 20 minutes, and then cooled to room temperature, which was used as the fermentation substrate.

[0040] (2) Inoculation of fermentation strains

[0041] Paenibacillus polymyxa (CGMCC1.15984; A bacterium), Brevibacterium paracondensa (CGMCC1.838; B bacterium), and Flavobacterium pectinosa (CGMCC1.12362; C bacterium) were respectively prepared with a viable count of 1× 10 6 The seed liquid, then 1; 1; 1 (volume ratio) mixed to prepare fermentation broth (total number of live bacteria is 1 × 10 6 ).

[0042] According to 10% mass ratio, under aseptic conditions, inoculate the mixed fe...

Abstract

The invention belongs to the technical field of agricultural product processing, and particularly relates to a fermentation process for preparing metabiotics by utilizing wheat processing byproducts. The process specifically comprises the following steps: preparing materials, inoculating paenibacillus polymyxa, brevibacterium paracaseum and flavobacterium pectinivorans as fermentation strains, performing separating, extracting and preparing metabiotics, and the like. In view of rich nutrient substance components in wheat starch wastewater and bran and in combination with a metabiotics preparation process, the process is beneficial to reducing the wastewater treatment cost of related enterprises and protecting the environment, besides, wastes can be turned into wealth, and the additional value of agricultural products is improved. Preliminary experiment results show that under the condition that no additional nutrient substances are supplemented, the content of symbolic products lipoteichoic acid and SCFA in the prepared metabiotics solution is high, on the basis, on one hand, a certain technical foundation can be laid for preparation of related health-care products, and a certain technical foundation is laid for prolonging the deep processing industry chain of wheat and improving the industry value of the deep processing technology.

Description

technical field [0001] The application belongs to the technical field of agricultural product processing, and in particular relates to a fermentation process for preparing postbiotics by using wheat processing by-products. Background technique [0002] In the process of wheat flour preparation, the main by-products include liquid wheat starch processing water (also called wheat starch wastewater) and solid wheat bran (seed coat sieved after wheat flour is ground). However, in the prior art, because these by-products have low nutrient content and are difficult to recycle, insufficient attention has been paid to these processing by-products, and targeted technology development and technical reserves are also relatively limited. [0003] In the technical field of food nutrition, postbiotic products are an important nutritional product based on probiotic products. Generally speaking, postbiotics refer to the metabolite components of probiotics processed by probiotics, including...
