Rice bran has been predominantly used in the feed industry, and only recently it has attracted greater attention in terms of human nutrition with increasing knowledge of its bioactivity. A growing interest is the analysis of physiologically active peptides derived from rice bran proteins. In this paper, the bioactivities of rice bran proteins hydrolysates and peptides are reviewed based on recent studies. These enzymatic hydrolysates and peptides exert various biological activities including antioxidant, antidiabetic, anticancer and inhibitory activity for angiotensin converting enzyme (ACE), which may ultimately prevent certain chronic diseases. Nevertheless, these functionalities can be highly associated with their corresponding structural characteristics, in particular specific sequences and molecular weight distribution. This article may facilitate the expansion of the prospective applications of the bioactive peptides in a number of fields and provide some clues of the relationship between peptides structure and functionality for future research.
