| dextrin | <chemistry> A translucent, gummy, amorphous substance, nearly tasteless and odorless, used as a substitute for gum, for sizing, etc, and obtained from starch by the action of heat, acids, or diastase. It is of somewhat variable composition, containing several carbohydrates which change easily to their respective varieties of sugar. It is so named from its rotating the plane of polarization to the right; called also British gum, Alsace gum, gommelin, leiocome, etc. See Achroodextrin, and Erythrodextrin. Origin: Cf. F. Dextrine, G. Dextrin. See Dexter. Source: Websters Dictionary (01 Mar 1998) |

| dextrin |
Dextrins are a group of carbohydrates produced by the hydrolysis of starch. They have the same general formula as carbohydrates but are of shorter chain length. Industrial production is generally performed by acidic hydrolysis of potato starch. Dextrins are water soluble, white to slightly yellow solids which are optically active. Analytically, dextrins can be detected with iodine solution, giving a red coloration. Cyclical dextrins are known as cyclodextrins. ...
