The relationship between Starch granule sizes and amylose content, swelling power and Zeleny sedimentation value were analyzed. The results indicated that the difference of size of starch granules in different wheat samples was obvious. Round, elliptic, and long-round type-A starch granules were found. The round or elliptic starch granules were larger than long-round starch granules generally. The bread quality characters of the samples with large type-A starch granules were better than that with small type-A starch granules. The correlation between starch granule diameter and swelling power was not significant, and negative correlation between starch granule diameter and amylose content, positive correlation between starch granule diameter and Zeleny sedimentation value were extremely significant. The research results provided a theory basis and guidance for quality improvement and food processing.Read More
