Abstract

The particle size distributions of starches prepared by proteolysis from different sized kernels of Maris Huntsman wheat, were determined by Coulter Counter. The number of starch granules was greater in “large plump” kernels than in “small plump” and “shrivelled” kernels grown under the same conditions. In all three kernel types more than one third of the total starch weight was contributed by granules less than 10 μm diameter (B type granules). The proportion of these small granules was significantly greater in “large plump” kernels than in the other two types.
