Abstract

The invention relates to the field of corn processing, and particularly discloses a method for preparing corn protein by a novel corn steeping process. The method comprises the following steps of soaking pretreated corn in a soaking solution which contains vitamin C; crushing the soaked corn, and performing separation to obtain corn protein. According to the method disclosed by the invention, vitamin C is used to completely or partly replace SO2 in a conventional process for soaking the corn, and the soaking effect equivalent to that of the conventional soaking process is achieved, and when the vitamin C is used to completely replace SO2 in the conventional process to soak corn, all products are free of SO2 residues and international food standards can be met; all of corn germs, corn fibers, corn starch and corn protein obtained by reprocessing of the soaked corn can be directly eaten; no desulfurization treatment is required; so that the production processes are simplified; and in addition, the soaking solution obtained after soaking is rich in nutrients and can be developed as a nutritional beverage or food supplement, and the like.

Description

technical field [0001] The invention relates to the field of corn processing, in particular to a method for preparing corn protein by a new process of soaking corn. Background technique [0002] Corn is one of the three major food crops in the world, and its products such as corn starch, corn protein, corn germ, and corn fiber are widely used in food, beverage, medicine, feed and other fields. How to obtain a higher yield of the above-mentioned products in production has always been a severe challenge faced by various countries and regions. [0003] At present, the deep processing of corn at home and abroad mainly adopts the wet milling production process, and SO is added to the corn soaking process. 2 . Due to the SO in its products 2 The residue is high and cannot meet the requirements of international food standards, so that the resulting product cannot be eaten directly. [0004] Therefore, there is an urgent need to develop a soaking method that can reduce the amoun...
