Rice bran is the hard outer layer of the rice grain, removed during the milling process. It is a valuable by-product that makes up about 10% of the rice kernel, and rice bran oil is extracted from this layer. It is rich in oil, dietary fibre, proteins, vitamins, and antioxidants. It is prized for its light taste, high smoke point, and health benefits, including cholesterol reduction. The bran also contains oryzanol, a natural antioxidant in nutraceuticals and cosmetics. In addition to oil extraction, rice bran is used as an ingredient in animal feed, fertilizers, and functional foods.

Rice bran is a cost-effective resource because it is widely available in rice-producing countries such as India, China, and Japan. With growing awareness of heart-healthy edible oils, rice bran is increasingly recognized as a premium raw material. Utilizing rice bran adds value to the rice milling industry and supports the sustainable use of agricultural by-products.
