1823 W. Henry Elements Exper. Chem. (ed. 9) II. x. 242 In this grain, Proust has discovered..a peculiar substance..to which he has given the name of hordein.
1830 M. Donovan Domest. Econ. I. iv. 73 Dr. Thomson is of opinion that the hordein..is merely starch in a particular state.
1865–72 H. Watts Dict. Chem. III. 167 Barley-starch obtained by kneading barley~meal in water, and leaving the liquid to settle..leaves a pulverulent substance, to which Proust gave the name hordein. It appears, however, to be, not a definite substance, but a mixture of starch, cellular tissue, and an azotised body.
