Dextrin, Grade : Industrial Grade

   Dextrins are prepared by heat treatment in presence of chemicals to suitably modify characteristics and properties of starch. They find application in dyes, adhesives, foundries, fire crackers, oil drilling and many other industries. Unlike starch dextrin are soluble in water. The severity of the treatment determines the degree of solubility ,which is the basis of classifying or grading dextrin. Finished dextrin are very fine powder varying in color from pure white to dark yellow.

Yellow dextrin  is manufactured by partially hydrolyzing Starch, using the dry roasting method in the presence of  catalyst: The dextrinisation chemically reduces the starch molecules into smaller components. Yellow dextrin has low viscosity and is very sticky and hygroscopic in nature. It is used in the foundry as a binder for cores. Yellow dextrin helps in increasing dry strength at the same time being completely soluble in water.
