Abstract

|
1-Palmitoyl-2-oleoyl-3-oleoyl glycerol (POO) and 1-palmitoyl-2-oleoyl-3-palmitoyl glycerol (POP) were enriched from palm stearin using an acetone fractionation process. Response surface methodology was employed to optimize the purity of POO (Y₁, %) and POP (Y₂, %) along with POO＋POP content (Y₃, g) based on independent variables such as fractionation temperature (X₁, 25, 30, and 35℃) and the ratio of palm stearin to acetone (X₂, 1:3, 1:6 and 1:9, w/v). Fractionation conditions were optimized to maximize Y₁, Y₂, and Y₃, in which fractionation temperature was 29.3℃ with a 1:5.7 acetone ratio. With such parameters, 60.9% of POP and 23.8% of POO purity were expected with a 75% yield (3.0 g) of POO and POP.
