The primary rice protein odorants were identified using static headspace analysis. Three sulfur-containing compounds were identified among the primary odorants. Acetaldehyde contributed significantly to the odor of RP-O but not other samples. The major lipid-derived odorants included hexanal, pentanal, and 2-pentayl furan. Metals, sulfite, and hydroperoxides were detected in rice protein samples.
