Enzymatic Determination of Starch in Wheat Fractions.

The Donelson-Yamazaki enzymatic procedure for estimation of damaged starch in soft wheat flour has been modified for use in the determination of starch in wheat fractions by a preliminary heat-gelatinization of the starch in the sample. The procedure is applicable to small quantities of sample. Starch determinations were made on wheat meals, flours, starches, and brans, and the data were compared with starch values obtained by the polarimetric procedure. The data were very highly correlated, and both methods performed comparably with respect to precision.
