Dextrin
Dextrin is actually a name for a type of low molecular weight carbohydrates. Dextrins are produced by enacting the process of hydrolysis on starches. Hydrolysis involves splitting water up into its basic components and allowing those components to attach to other molecules.

There are several types of Dextrin and they have related formulas. They are produced through acidic hydrolysis performed on potato starches. And, they are soluble in water.
Some dextrin react with iodine to give a blue color and is soluble in 25% alcohol (called amylodextrin); others a reddish-brown color and soluble in 55% alcohol (called erythrodextrin); and still others yield no color at all with iodine and soluble in 70% alcohol (called achrodextrin

Commercial dextrin

Any of various soluble polysaccharides obtained from starch by the application of heat or acids and used mainly as adhesives and thickening agents.
High-grade dextrins are prepared by heating starch which has been moistened with a smallquantity of dilute nitric acid and dried,at 110-115c.the product is known as white dextrin.inferior dextrin,which have a yellow or brown colour ,are prepared by roasting starch at 150-250c without tthe addition of acid.
White dextrin may contain up to 15% of soluble starch,the remainder consisting largely of erythrodextrin. Yellow dextrins are more completely hydrolysed and, unlike th ewhite variety, containappreciable quantities of maltose,which may be detyected and estimated by means of Fehling’s solution.
Dextrin sentence examples * Through digestion or with food processing, starches can be partially broken down to smaller chains, called dextrins. * Malt dextrin contains between 9 and 11 molecules of glucose in a long chain.
Uses of dextrin
Dextrin forms a strongly adherent paste when mixed with water and it is used as adhesive in the manufacture of gummed
