Method for producing mucus protein of sweet potato from wastewater of sweet potato f

Abstract

This invention discloses a method for preparing Ipomoea batatas mucilage proteins from Ipomoea batatas starch wastewater. The method comprises: filtering Ipomoea batatas starch wastewater coarsely at normal temperature, micro-filtering by membrane separation in vacuum, incorporating the above two filter cakes, freeze-drying or vacuum-drying, and pulverizing to obtain powdery Ipomoea batatas mucilage proteins. The method has such advantages as comprehensive utilization of Ipomoea batatas starch wastewater, reduced environmental pollution, high profit, advanced technique, high efficiency and retained activity of Ipomoea batatas mucilage proteins.

Description

technical field

[0001] The invention relates to a method for preparing sweet potato mucus protein from sweet potato wastewater. Background technique

[0002] Many domestic enterprises that produce sweet potato starch discharge a large amount of sweet potato wastewater when processing starch. According to investigations, an enterprise with an annual output of only 1,000 tons of sweet potato starch discharges more than 20,000 tons of sweet potato wastewater every year, of which more than 100 tons of sweet potato mucus protein is discarded. It not only wastes protein resources, but also pollutes the environment. Sweet potato mucus protein is a mixture of polysaccharides and proteins. It has high nutritional value and special functional activity. It can restore damaged immune mechanisms, improve human immunity, and has anti-tumor, anti-virus and anti-aging effects. Maintain the elasticity of human blood vessel walls, inhibit lipid deposition and atherosc...
