摘要: ABSTRACTIn this study, response surface methodology was utilized to determine the optimal conditions for extraction of carotenes (α- and β-carotene) tocols (α-tocopherol, α-, γ-, δ-tocotrienol) from crude palm olein using ethyl lactate (EL) ethanol (EtoL) in a temperature-controlled mixer-settler system. Central composite design with four factors including temperature (X1), mixing time (X2), volume fraction (VF) (X3), VF EtOL (X4) used investigate multivariate relationship five responses enrichment factor recovery both tocols. The optimum were determined at 20°C, 10 min mixing, 48% olein, 31.2% EL 20.8% EtoL (corresponding 0.5 0.4 EtoL). 0.88 2.56, respectively while 11.3% recovered.
