Valorization of Industrial Byproduct-Rice Bran Acid Oil: Direct ...
Rice bran acid oil (RBAO) is a free fatty acid-containing byproduct derived from the neutralization step of rice bran oil refinery. It is usually used as a low-value product for animal feed. Given the large amount of bioactive compound, γ-oryzanol, in the RBAO, there is the opportunity to redeploy RBAO as a source for other high-value products.

The refined rice bran oil obtained from fresh rice bran (without lipase action) contained about 90% of triacylglycerols whereas, the refined oil from that of high FFA bran oil showed about 10% triacylglycerols. Hence the latter cannot be used as an edible oil, but instead can be used at low levels as a nutraceutical in foods. PRACTICAL APPICATIONS

byproducts. Rice bran is a by-product of rice milling that contains 15-23% lipids and a significant amount of nutraceutical compounds. Due to the presence of active lipase in the bran and the lack of economical stabilization methods, most bran is used as livestock feed or boiler fuel and most rice bran oil (RBO) produced is not of edible grade.

De-oiled rice bran (DORB) is obtained after oil is removed from the rice bran. This is the commonly used ingredient in the feeding of Indian major carps due to its cheaper cost. DORB is used as a feed ingredient in cattle, poultry, and fish diet. Along with this, they are also used in making fiber-rich biscuits and extraction of an antioxidant compound like oryzanol and other industrial uses ...

Rice bran and other rice by-products | Feedipedia
Rice bran is the most important rice by-product. The bran fraction contains 14-18% oil. Rice bran that has not been defatted is a useful binder in mixed feeds. Defatted rice bran can be used at higher levels than ordinary rice bran. Rice bran is often adulterated with rice hulls, as it should have a crude fibre content of 10-15% (Göhl, 1982).
