Abstract

The invention provides a microbial degumming method of a corn bran fiber. The method is characterized by comprising the following steps of (1) selecting corn bran without mildewing, (2) performing soaking pretreatment on the corn bran fiber, (3) performing aspergillus niger HYA4 solid fermentation to prepare microbial degumming liquid of the corn bran fiber, (4) performing microbial degumming on the corn bran fiber, (5) performing potassium hydroxide solution soaking, and (6) performing water washing and drying to obtain the corn bran fiber. The method is low in corn bran fiber damage; and the prepared corn bran fiber is lower in residual gum content, higher in strength and soft.

Description

technical field [0001] The invention relates to a preparation process for reusing crop waste, in particular to a microbial degumming method for corn husk fiber, and belongs to the technical field of renewable resource utilization. Background technique [0002] Humans have a long history of planting corn. In my country, the sown area of ​​corn is second only to rice and wheat, and ranks third among food crops. In addition to harvesting corn kernels as food every year, a large amount of corn husks will also be produced. This is a huge and valuable resource, but it has not been rationally and effectively developed and utilized for a long time. Most of the corn husks are used for cooking and heating, and the rest are abandoned in the fields or burned, which not only frequently causes fires and other accidents, seriously pollutes the environment, but also causes a great waste of resources. Degumming corn husks to obtain corn husk fibers realizes the reuse of waste corn husks, wh...
