Physicochemical properties and stability of palm olein and rice bran oil blends / Nor Idayu Ismail

The objectives of this study were to determine the changes in the physicochemical porperties of the oil after blending, to determine the stability of the oil blends and to identify the best mixing ratio for frying oil. Palm olein (POo) was blended with rice bran oil (RBO) at different ratios of 30:7...
