dextrin
n 1: any of various polysaccharides obtained by hydrolysis of

The Collaborative International Dictionary of English v.0.48 (gcide)

Dextrin \Dex"trin\, n. [Cf. F. dextrine, G. dextrin. See
{Dexter}.] (Chem.)
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}.
[1913 Webster]
