Dextrins are starch hydrolysis products. They are a mixture of substances of varying degrees of breakdown of the starch molecule. The production of dextrins consists in heating dry potato meal at a temperature of about 200 ° C, in the presence or absence of acids. A common feature of all dextrins is their insolubility in alcohol, thanks to which alcohol precipitates out of the aqueous solution.
Yellow dextrin - obtained from starch is used for molding sands for small and medium castings. Yellow dextrin is used in the paper, foundry, printing and many other industries.
