Dextrin - White And Yellow Powder Varieties, Versatile Applications In Adhesives And Manufacturing

Dextrin
Dextrin are starch
converted products primarily used in of carbon paper manufacturing,
tube manufacturer, corrugated boxes, book-binding.

Yellow Dextrin
White dextrin is
prepared by heating dry starch in the presence of an acid at a
temperature generally below 150C. White dextrin may also be obtained
by further continuing the acid process for making thin boiling starches.

White Dextrin
Yellow dextrin are
prepared in a similar manner but at a higher temperature and using less
acid. Apart from depolymerization,a good deal of internal rearrangement
occurs with formation of highly branched molecules.

Dextrin does not react with chemicals. Because of this ability, dextrin plays an important role to various industries.
