چکیده انگلیسی
We identified a new interesterification reaction between tripalmitin and dicarboxylic acid using lipase. Tripalmitin and dicarboxylic acid were incubated at 70 °C for 72 h with Lipozyme® RM IM. The reaction mixture was analyzed by MALDI TOF-MS and liquid chromatography/mass spectrometry. The products found were a dimer [(α(γ),β-dipalmitoyl)-glyceryl]-γ(α)-(Ï-carbooctadecanoyl)-αâ²(γâ²),βâ²-dipalmitoyl-glycerol and oligomers of glyceride. This dimer was also found in Japan wax, traditionally used as cosmetics.
