BACKGROUND: The purpose of this study was to produce triacylglycerols (TAGs) enriched in pinolenic acid (PLA) at the sn-2 position using the principle of acyl migration, from the pine nut oil containing PLA esterified exclusively at the sn-3 position. RESULTS: Two types of lipase-catalysed reactions, i.e. redistribution and reesterification of fatty acids, were successively performed using seven commercially available lipases as biocatalysts. Of the lipases tested, Novozym 435 and Lipozyme TL IM were effective biocatalysts for positioning PLA at the sn-2 location. These biocatalysts were selected for further evaluation of the effects of reaction parameters, such as temperature and water content on the migration of PLA residues to the sn-2 position and TAG content. For both lipases, a significant decrease in TAG content was observed after the lipase-catalysed redistribution of fatty acids for both lipases. The reduced TAG content could be enhanced up to approx. 92%, through lipase-catalysed re-esterification of the hydrolysed fatty acids under vacuum. CONCLUSION: TAG enriched in PLA at the sn-2 position was synthesised from pine nut oil via lipase-catalysed redistribution and re-esterification of fatty acid residues using Lipozyme TL IM and Novozym 435 as biocatalysts.
