Stickiness of oryzenin and starch mixtures from preharvest and postharvest rice grains.

Stickiness, molecular weight, binding, sulfur bridges, and amylose of isolated oryzenin (rice storage glutelin) and/or starch from preharvest and postharvest rice grains were studied. The molecular weight, amylose content, and stickiness of starch did not change significantly during preharvest ripening or postharvest storage of rice, but the stickiness of oryzenin and its mixtures with starch increased during ripening and decreased during postharvest storage. The stickiness of oryzenin or oryzenin-starch mixtures from preharvest and postharvest rice grains was related to its average molecular weight, cystine bridges, and the oryzenin-starch equilibrium binding constant.
