Starch was identified and isolated from mature Amsoy 71 soybeans. Starch also was identified in ten different soybean cultivars. The starch from Amsoy 71 soybeans contained 15-20% amylose, was estimated to be 0.80 +/- 0.03% of the dry weight, had a density of 1.51 g/ml, and had a gelatinization temperature in the range of 73-81 C. The starch granules were smooth ovoids averaging 3 micrometers in length, existed as compound granules in the amyloplast, and were abundant near the center of the cotyledon but less prevalent near the periphery.
