Abstract

The invention provides maltooligosyl glucoside, and a preparation method and application thereof. The preparation method comprises the following steps of: (1) dissolving starch in water to prepare starch milk; (2) adding pullulanase, [beta]-amylase and medium-temperature [alpha]-amylase into the starch milk obtained in (1), carrying out liquidation reaction, and then, obtaining liquidation liquid;(3) carrying out saccharification reaction on the liquidation liquid obtained in (2), and then, obtaining saccharification liquid; and (4) carrying out hydrogenation reaction on the saccharificationliquid obtained in (3), and then, carrying out drying to obtain the maltooligosyl glucoside. The method has high production efficiency and a low production cost, no additive agents are added in a whole process, and a product is safe and harmless, does not have any irritation for the skin and has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of daily chemicals and relates to a maltooligosaccharide glucoside and its preparation method and application, in particular to a maltooligosaccharide glucoside of good quality and its preparation method and application. Background technique [0002] Maltooligosaccharide glucoside is a viscous, colorless mixture formed by natural plant fermentation. It is a polysaccharide substance in structure, contains many hydroxyl groups, and has strong hydrophilicity. It is an important ingredient in the field of daily chemicals. moisturizer. It can reduce the irritation of the cosmetic system, keep the foam delicate and long-lasting in washing, and reduce the tightness and irritation caused by excessive cleaning caused by surfactants. After drying on the skin surface, it can form a breathable film, which is very smooth and has a certain oil control effect. But at present, there is no efficient, safe and harmless open and compl...
