During the dry conversion of Dextrin, the chemical reaction mechanism of starch is complex, mainly including hydrolysis, glycosidic bond transfer and reaggregation.
1) Hydrolysis reaction. The hydrolysis reaction mainly occurs in the pre drying process and the dextrin conversion stage. In the conversion hydrolysis stage, acid continuously catalyzes α- 1,4 glycosidic bond and α- The breaking of 1,6 glycosidic bond continuously reduces the molecular weight of starch, which is also reflected in the increase of reducing end groups formed by hydrolysis of glycosidic bond. The viscosity of dextrin products is basically determined by hydrolysis reaction. The starch viscosity corresponding to high hydrolysis degree is low. The main components of hydrolysis reaction are low molecular oligosaccharides and glucose.
2) Glycosidic bond reaction. Under heated conditions α- The 1,4 glycosidic bond will break, resulting in glycosidic bond transfer, and the adjacent free hydroxyl will recombine with it to form a branch structure.
3) Reunion reaction. In the presence of acid, the glucose produced by hydrolysis has the ability to reunite and function at high temperature. In the presence of water, reaggregation and hydrolysis occur successively.
Yellow dextrin is widely used in abrasives, sand casting, refractory materials, rubber products and other industries, especially in abrasives and refractory materials, refractory furnace materials, light bricks, profiled bricks, etc. It has excellent effect on the initial shaping of its products. According to the appropriate proportion, it can be mixed in evenly. In modeling, it has a good effect on preventing collapse, angle and edge protection.
Resistant dextrin is a kind of white or light yellow powder or light yellow liquid, with slightly sweet taste, low viscosity and no other odor, and good water-solubility with a pH of 4.0-6.0

Dextrin is a carbohydrare that is a water-solube polysaccharide formed by the hydrolysis of starch ,itself a carbohydrarte .We cleave or break the very long chain called starch via hydrolysis ,we get a bunch of shorter but still pretty long chains ,that is dextrins .Yellow Dextrin ,which is also called canary dextrins ,it is easy mixed with water than original starch .DM-yellow tapioca dextrin is artificially produced from high quality tapioca starch using acid ,which can be used for food and industrial .
White Dextrin is a natural small molecular water-soluble dietary fiber obtained the enzymatic hydrolysis of corn starch and then spray drying.
Yellow dextrin has strong applicability and wide application
It is widely used in sewage treatment, textile industry, printing and dyeing industry, paint industry, construction industry, packaging industry, chemical industry, etc.
