Abstract

The invention discloses a production method for preparing isomahooligosaccharide from waste residues of sweet potatoes. The method includes: adding medium-temperature alpha-amylase into the waste residues of the sweet potatoes, heating, gelatinizing and liquefying; saccharifying by intrinsic beta-amylase in the waste residues of the sweet potatoes to obtain maltose; adding alpha-glucosyltransferase to realize glucoside conversion of the maltose to generate maltooligosaccharide. The production method has the advantages of simplification of technical process, low heat consumption and excellent targeting property by combination of existing production process of sweet potato starch processing enterprises and characteristics of fresh sweet potato residues, thereby being suitable for popularization in the sweet potato starch production enterprises.

Description

technical field

[0001] The invention belongs to the technical field of resource utilization of sweet potato dregs and the field of food processing, and in particular relates to a method for preparing isomaltooligosaccharides from sweet potato dregs as raw materials. Background technique

[0002] Isomaltooligosaccharides (IMO for short) are a type of oligosaccharides in which the number of monosaccharides ranging from 2 to 6 is formed by the combination of glucose groups with α-1,6 glycosidic bonds. Isomaltooligosaccharides can promote the growth of probiotics such as bifidobacteria and lactic acid bacteria, adjust the balance of intestinal flora, promote intestinal peristalsis, prevent and relieve constipation and diarrhea, prevent dental caries, and inhibit the growth and corruption of intestinal harmful bacteria Matter is generated. Because isomaltooligosaccharide has many excellent properties and health-care physiological functions, it has been widely used in health care...
