Chicken fat and sunflower oil 2:3 m/m blend was enzymatically interesterified at 60°C with and without microwaves assistance. As the catalyst a commercial preparation of the immobilized lipase from Rhizomucor miehei (Lipozyme RM IM) containing 2% of water was used, and the catalyst load was 8% in each case. The starting mixture and the interesterified products were separated by column chromatography into pure triacylglycerols fraction (TAG) and a non-triacylglycerol fraction, which contained free fatty acids (FFA), mono- and diacylglycerols (MAG and DAG). The oxidative stabilities (OS) of fats studied and TAG derived from them were assessed by Rancimat at 100°C and by Pressure Differential Scanning Calorimetry (PDSC) under oxygen at 110-140°C. Interesterification reduced the OS of chicken fat and sunflower oil blend. The main factors influenced on the OS of fats studied were concentrations of tocopherols and presence of FFA, MAG- and DAG. The structures of TAGs were of minor importance. From the resulting PDSC exotherms their times to reach the onset (τon) and peak maximum (τmax) were measured and used for calculations of parameters of the Arrhenius type kinetics for thermaloxidative decomposition of fats studied.
