ABSTRACTChemical interesterification reaction conditions that provide regioselectivity regarding fatty acid positions in triacylglycerol have been investigated. Sodium methoxide-catalyzed ester interchange between soybean oil and methyl stearate was performed in hexane at low reaction temperature,i.e., 30 to 60°C. The results showed regioselectivity was obtained at 30°C. The ester interchange at 1,3-carbons progressed 1.7 times faster than at 2-carbon of the glycerol moiety of triacylglycerol at 24 h. Preheating of the mixture of reactant and catalyst at 60°C for 15 min promoted catalyst activation to accelerate the interesterification while maintaining regioselectivity. This method is believed to be feasible for modification of edible fats and oils. More... »
