Production of biodiesel from rice bran oil - ScienceDirect

Rice bran is a byproduct of the milling process of paddy rice to produce refined rice. Rice bran oil (RBO) is a valuable domestic oil resource in many countries, its acceptability as an edible oil has been hampered because of its commonly high free fatty acid (FFA) content resulting from the high lipase activity of the bran.

Chemical Modification of High Free Fatty Acid Oils for Biodiesel Production

Despite challenges, biodiesel feedstocks from oil and fats with high FFA have shown to be a potential feedstock for low-cost biodiesel production. The effect of high free fatty acid in the base transesterification process can be eliminated by modifying them into soap stock by neutralization process, converting them into esters by acid esterification process, or reesterifying them into ...
