The following free lipases (Lipase AP, Aspergillus niger; Lipase P, Pseudomonus sp.; Lipase AY, Candida rugosa; Lipase AK, Pseudomonas fluoresescens; Lipase F, Rhizopus oryzae; Lipase D, Rhizopus delemar) were screened under selected reaction conditions. The conditions were enzyme load 5%, substrate mole ratio 1:6 (fish oil: caprylic acid), and reaction temperature of 50C. Lipase AK had the highest activity and was suitable for production of structured lipids from fish oil. The optimal mole substrate ratio of fish oil to caprylic acid for Lipase AK was 1:6 to 1:8.
