Rice fiber (RF) and rice bran oil (RBO) were added to restructured beef roasts as natural additives. Beef roasts containing either RF or RF/RBO had higher oxidative stability (P<0.05) during storage at 4C than did beef roasts without additives (control). The TBARS values, the saturated fatty acid / unsaturated fatty acid ratio (SFA/UFA), and the 7‐ketocholesterol content of beef roasts with RF and RF/RBO were lower (P<0.05) than those of controls during storage (0, 4, and 8 days). Vitamin E vitamers and UFA were higher than those of controls. Preliminary sensory data indicated beef roasts containing RF and RBO were acceptable to consumers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
