The quality of rice bran and its oil is usually determined as total
FFAs content in the oil (Bhosle and Subramanian, 2005). It is expressed
as oleic acid percentage in RBO (Zappe, 1997). Another
important indicator for RBO quality is acid value (AV) which measures
the amount of acid present in oil. AV is the required amount
of potassium hydroxide for neutralization of one gram of oil.
