What is the difference between white cyclodextrin and yellow cyclodextrin?

White dextrin is used in the pharmaceutical industry, protective adhesives and suspensions, adhesives, such as paper gluing, textile sizing, ink formulation, etc; It is also used as a substitute for drug excipients.
Yellow dextrin is widely used in industries such as grinding tools and abrasives, sand casting, refractory materials, and rubber products, especially in grinding tools and refractory materials, refractory furnace materials, lightweight bricks, shaped bricks, etc. It has excellent effects on the initial shaping of its products. When mixed in an appropriate ratio and stirred evenly, it plays an excellent role in preventing collapse and maintaining corners and edges during shaping.
Cyclodextrin is a partially degraded oligomer produced from starch through baking, oxidation, or acid decomposition. During degradation, some 1,4 glycosidic bonds are broken, resulting in the formation of many short molecular chains and the formation of 1,6 linkages, leading to the formation of many branched chains. Different varieties can be produced depending on the degradation conditions and degree.
1. White dextrin is a product obtained by treating corn starch with dilute nitric acid at around 200 ℃, and its color is pure white. Yellow dextrin is made by hydrolyzing starch at around 180 ℃, with a yellow brown color.
2. Starch is present in white dextrin, while yellow dextrin contains very little starch but is mixed with a small amount of glucose. Made from hydrolyzed starch at around ℃, with a yellow brown color.
