ethanol as a solvent and found ethanol is
economical when compared to n-hexane. Sivala et al. (1993)
conducted experiments on the critical solubility temperature
of rice bran oil. The aim of this investigation was to establish a
suitable method for quick determination of oil content in
miscella and to determine the critical solubility temperature
(CST) of rice bran oil in aqueous ethanol and ethanol hexane
mixtures by using solvent extraction method. When
hexane was added, the critical solubility temperature
value decreased.
