Three typical U.S. rice varieties were studied for differences after storage for 1 year at temperatures between 4 and 40 o C. In this manner, rice samples with a relatively wide range of physicochemical and functional properties were obtained. From t

Peptide subunits of oryzenin preparation from postharvest and stored rice grains of the two typical U.S. rice varieties (long and medium grain) have been studied by SDS-PAGE. Both studied varieties of the postharvest and/or stored rice had similar qu

A new method for the analysis of organic structural groups from absorption spectra is described. The method is based on the integrated intensity of absorption. It requires only micrograms of analyzed compound, which may be fully recovered after analy

Changes in oryzenin (rice storage protein) and starch during the preharvest maturation (14, 30, and 50 days after flowering) of rice grains have been studied. During the synthesis of oryzenin the cysteine content slightly decreased but the cystine br
