COMPREHENSIVE EXPLOITATION AND UTILIZATION OF DEFATTED RICE BRAN IN AQUATIC FEED

Rice is the staple food of almost all Asian countries and rice bran is the agricultural by-product of rice milling industry. Its by-product, defatted rice bran (DRB), which contains a number of valuable components - for example, proteins, carbohydrates and other phytochemicals - that exhibit health benefits. Direct use of the rice bran is problematic, because it rapidly becomes rancid due to the hydrolysis of neutral fat by highly active lipase enzymes right after the milling. Therefore DRB is considered a good source of aquatic feed. The aim of this study was to compare of rice bran and defatted rice bran. Subsequently, the contrast test results between DRB and wheat were described. A novel strategy of the replacement rice bran with DRB followed by experiment was proposed. Based on the results of this study, DRB can be a good source of aquatic feed that is suitable for applications in aquaculture industry and other new applications such as a potential material in the biomedical field.
