Abstract

The invention discloses a preparation method for wheat bran dietary fiber. According to the method, double modification of steam explosion treatment and lactobacillus fermentation is performed on wheat bran, and a post-treatment step is performed to obtain the dietary fiber; and insoluble dietary fiber and water-soluble dietary fiber can be obtained simultaneously. The extraction rate of the dietary fiber is increased, the composition and structure of the dietary fiber are changed, and the physiological activity of the dietary fiber is improved.

Description

technical field [0001] The invention relates to a food processing method, in particular to a processing method of wheat by-products, in particular to a preparation method of wheat bran dietary fiber. Background technique [0002] my country is a big country in wheat production, consumption and export, and its total wheat output and export volume rank among the top in the world. Every year, the wheat processing industry produces large quantities of by-products such as bran, which are a rich source of natural dietary fiber. However, these by-products are not well utilized. Therefore, the reasonable and comprehensive utilization of wheat processing by-products as raw materials in different levels and to avoid environmental pollution to the greatest extent is in line with the needs of sustainable development of human resources. Using wheat bran, a by-product of wheat processing, as raw material to prepare high-quality wheat dietary fiber, not only realizes zero waste in wheat ...
