    The Reesterification of Rice Bran Oil
    (1972) Carolina R. Medina
    Studies have been made on the reaction of rice bran oil with added glycerol in order to utilize the reaction as a possible means of lowering the free fatty acid content of high acid oils. Results show that reesterification is favored by an increase in temperature and an increase in glycerol concentration. Time temperature concentration interactions are indicated. Addition of catalysts, notably MnO2, ZnCl2, and PbO, favors reesterification resulting in the significant decrease in free fatty acids. Examination of the reaction product shows that the reaction leads to a change in glyceride composition of the oil.
