Abstract

Incorporations of nature fatty acids which were palmitic acid and stearic acid into the end positions of soybean oils were done using sn-1,3 specific immobilised lipase from Rhizomucor miehei at different ratios in order to produce symmetrical triglycerides without changing the fatty acids at sn-2 position. The optimum ratio for the process was 25:75 w/w. There were 19.2% increase of SFA for P25 and 16% increase for S25 at the sn-1,3 positions. The research findings indicated that the structured lipids produced from enzymatic interesterification possessed a higher oxidative stability than soybean oil. The newly formed structured lipids (SUS type) could be good sources for various applications in food industry.
