Rice bran oil (RBO) is unique among edible vegetable oils because of its unique fatty acid composition, phenolic compound (γ-oryzanol, ferulic acid) and vitamin E (tocopherol and tocotrienol). It has become a great choice of cooking oil because of its very high burning point, neutral taste and delicate flavour.
Which countries use rice bran oil?
It is popular as a cooking oil in East Asia, the Indian subcontinent, and Southeast Asia including India, Nepal, Bangladesh, Indonesia, Japan, Southern China and Malaysia. Rice bran oil has a composition similar to that of peanut oil, with 38% monounsaturated, 37% polyunsaturated, and 25% saturated fatty acids.
What is rice bran?
Rice bran is obtained from outer layer of the brown (husked) rice kernel during milling. It has emerged as potential by-product from rice processing industry due to the increasing demand for rice bran oil (RBO) as healthy functional food ingredients.
How is rice bran stabilized?
The rice bran was stabilized using microwave heating to inactivate endogenous lipase enzymes that would otherwise cause rancidity of the oil and render it inedible. The oil was then extracted and evaluated for its physicochemical properties, fatty acid composition, and antioxidant activity using standard methods.
