Abstract

The invention relates to a preparation method of isomaltooligosaccharide, which comprises the following steps: (1) adding water to the starch raw material to adjust the slurry concentration, and adding high-temperature-resistant α-amylase after adjusting the pH to prepare the starch slurry; (2) adding After the starch slurry is kept warm, it is liquefied by secondary injection to obtain a liquefied liquid; (3) adding α-glucosidyl transferase to the liquefied liquid, and after the reaction, the enzyme activity is inactivated to obtain a transglycoside sugar liquid; (4) the transglycosidic sugar liquid is obtained; The glycoside sugar solution is decolorized, filtered, separated, chromatographically separated, concentrated and dried to obtain isomaltooligosaccharide. The invention reduces the degradation of sugars with a polymerization degree ≥ 3 by glucoamylase, so that the reacted feed liquid components are mainly sugars with a polymerization degree ≥ 3, such as panose, isomaltotriose, and tetrasaccharide, and because the saccharification process is omitted, the reaction The time is shortened by 20‑30 hours, the production efficiency is greatly improved, and the comprehensive cost savings reaches 10%.

Description

technical field [0001] The invention relates to a preparation method of isomaltooligosaccharide, which belongs to the technical field of functional sugar production. Background technique [0002] Isomaltooligosaccharide, also known as branched oligosaccharides, refers to 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. Different, in order to distinguish it from maltose, it is called isomaltooligosaccharide. [0003] Isomaltooligosaccharide has good physical and chemical properties and physiological functions, such as low sweetness, which is 40% to 50% of sucrose, and the sweetness is soft and delicious, and the taste is refreshing; it is difficult to be digested by gastric enzymes, and the calorie is low, basically does not increase Blood sugar and blood lipids; promote the proliferation of bifidobacteria in the human intestinal tract, and can inhibit the formati...
