The different particle sizes of fine and coarse wpf, however, did not exhibit the same trend on the starch digestibility, which might be explained by that: (1) the differences in the particle-size distributions between coarse and fine wpf were not as significant as those between coarse and fine rpf and (2) wpf consisted of considerably more.
The physicochemical, functional and digestibility characteristics to those products. Starch (native state) is organized into discrete particles called granules; the biosynthesis of granules initiates at the hilum, and then they grow by apposition.
