摘　　要：Refined soybean oil and lard were interesterified in the presence of a basic anion exchange resin as heterogeneous catalyst. The structural composition of the interesterification products was determined by 1,3 specific lipase hydrolysis method followed by chromotographic analysis. The influences of the acidity of reactants, reaction time and reaction temperature on the interesterfication have been investigated. The experimental results showed that a mixture of 60% soybean oil and 40% lard(in mass ratio) with acid value of 0 116 was found to have remarkable interesterification at 50℃, for 150 min by using 10% basic anion exchange resin as a catalyst. The melting point of the final product was 37 6 ℃.
