黄糊精 - Uses and synthesis methods

introduction

Dextrin is an incomplete hydrolysate made from starch by acid or heat treatment or alpha amylase. It is a yellow or white amorphous powder. Soluble in hot water, slightly soluble in cold water, insoluble in ethanol.

application

High-quality yellow dextrin can be almost 100% dissolved in cold water, with low viscosity and good fluidity. It has the basic properties of bonding cellulose raw materials, forming water-soluble films and bonding inorganic materials. Therefore, yellow dextrin is widely used in the field of binder, and can be used as binder such as casting sand, coal brick, plaster, etc., as well as pigment thickener in textile printing and dyeing industry, microcapsule wrapping agent for pharmaceuticals, and coating machine in paper industry. In addition, yellow dextrin can also be used as a substrate for fermentation culture, cement hardening retarder, as well as for photosensitive auxiliary materials, floating mineral processing and other industries.

production method

starch is first made from dried yam taro, then the starch is heat-treated, and the finished product is obtained after screening.
