An infant formula fat analog with capric acid mostly esterified at the sn ‐1,3 positions, and substantial amounts of palmitic, docosahexaenoic (DHA), and arachidonic (ARA) acids at the sn ‐2 position, was prepared by physically blending enzymatically synthesized structured lipids (SL) with vegetable oils. The components of the blend included high sn ‐2 palmitic acid SL enriched with capric acid (SL CA ), canola oil (CAO), corn oil (CO), high sn ‐2 DHA (DHAO m ), and high sn ‐2 ARA (ARAO m ) enzymatically modified oils. Each component was proportionally blended to match the fatty acid profile of commercial fat blends used for infant formula. The infant formula fat analog (IFFA 1 ) was characterized for total and positional fatty acids (FA), triacylglycerol (TAG) molecular species, thermal behavior, and tocopherol content. IFFA 1 contained 17.37 mol% total palmitic acid of which nearly 35 % was located at the sn ‐2 position. The total capric acid content was 13.93 mol%. The content of DHA and ARA were 0.49 mol% (48.18 % at sn ‐2) and 0.57 mol% (35.80 % at sn ‐2), respectively. The predominant TAG were OPO (24.09 %), POP (15.70 %), OOO (11.53 %), and CLC (7.79 %). The melting completion and crystallization onset temperatures were 18.65 and −2.19 °C, respectively. The total tocopherol content was 566.45 μg/g. This product might be suitable for commercial production of infant formulas.
