Bioactive compounds from by-products of rice cultivation and rice processing: Extraction and application in the food and pharmaceutical industries

摘要

Background: Rice by-products, including straw, husk and bran, are generated through rice cultivation and rice milling processes and have been considered as rich sources of bioactive compounds, such as essential amino acids, phenolics, flavonoids, vitamin E and gamma-oryzanol. These compounds are generating interest due to their potential beneficial effects on human health, in addition to their antioxidant capability for improving the storage stability of foods. Nevertheless, a large amount of rice by-products is not efficiently utilized, which leads to economic waste and environmental problems.
