Abstract Novel structured triacylglycerols (STAGs) enriched with unsaturated fatty acids (UFAs) and low palmitic acid (PA) content were firstly synthesized from Schizochytrium sp. oil and oleic acid (OA) via solvent-free acidolysis catalyzed by Lipozyme RM IM. The results indicated that, the PA content decreased from 24.49\% to 6.95\%, while the UFAs content increased from 70.20\% to 90.9\% at the sn-1,3 positions in the STAGs under the optimal condition (i.e., lipase load of 7\%, molar ratio of microalgae oil TAGs to OA of 1:3, and temperature of 65 °C). The lipase Lipozyme RM IM could be reused 16 times without significant loss of activity. The improved plastic and storage ranges of STAGs are useful for infant formula formulations, by which a possible method is blending of this product and 1,3-dioleoyl-2-palmitoylglycerol enriched fats and minor lipids based on the corresponding chemical compositions of human milk fat.
