Abstract

Physicochemical characteristics of binary blends containing refined-deodorized-bleached palm oil (RBDPO) and sunflower oil (SFO) were studied before and after chemical interesterification at different temperature (110 oC (CIE1) and 80 oC (CIE2)) using sodium methoxide as catalyst. Thirty-three samples with different ratios were analyzed for triacylglycerol (TAG) composition, fatty acid composition (FAC) and solid fat content (SFC) profile. Upon CIE, extensive rearrangements of fatty acids among triacylglycerol (TAG) were seen. Generally, CIE not induced enormous changes in the TAG compositions of ratio 8:2 and 5:5 of RBDPO:SFO blends. However, CIE induced enormous changes in the TAG compositions of the 9:1, 7:3, 6:4, 4:6, 3:7, 2:8 and 1:9 blends, which some of the TAGs were increasing while the other decreasing. These changes in TAG profiles resulted in some changes in the physical properties (especially SFC) of the blends. Generally, the SFC of interesterified blend were decreased after CIE1 and increased after CIE2, except for sample 10:0, 8:2, 7:3, 5:5 and 9:1 which were decreased after CIE1 and CIE2. As a conclusion, CIE1 and CIE2 successfully changed the physicochemical characteristics of the binary blends.
