Of the lipases tested, Novozym 435 and Lipozyme TL IM were effective biocatalysts for positioning PLA at the <jats:italic>sn<\/jats:italic>\u20102 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 <jats:italic>sn<\/jats:italic>\u20102 position and TAG content. For both lipases, a significant decrease in TAG content was observed after the lipase\u2010catalysed redistribution of fatty acids for both lipases. The reduced TAG content could be enhanced up to approx. 92%, through lipase\u2010catalysed re\u2010esterification of the hydrolysed fatty acids under vacuum.<\/jats:p><jats:p><jats:bold>CONCLUSION:<\/jats:bold> TAG enriched in PLA at the <jats:italic>sn<\/jats:italic>\u20102 position was synthesised from pine nut oil via lipase\u2010catalysed redistribution and re\u2010esterification of fatty acid residues using Lipozyme TL IM and Novozym 435 as biocatalysts.
