Strategies for Enzymatic Synthesis of Omega‐3 Structured Triacylglycerols from Camelina sativa oil enriched in EPA and DHA - Natalia Castejón F. Javier Señoráns - European Journal of Lipid Science and Technology, 2019
Summary: The transesterification method of 2‐MAGs from vegetable omega‐3 sources like camelina oil, with marine EPA and DHA FAEEs, opens new approaches for developing VLC‐PUFA fortified functional foods. Results demonstrate the efficiency of this enzymatic method for enriching camelina oil in EPA and DHA, and offer a very effective strategy for the development of omega‐3 enriched products from other vegetable oil sources like chia or echium as ingredients for functional foods with recognized health claims for applications in nutraceutical and food industries. Camelina oil proved to be an excellent source to enzymatically produce 2‐MAGs enriched in omega‐3 ALA. Moreover, lipase screening with commercial biocatalysts established the most appropriate strategy to reach maximum STAGs yields with direct application in industry. Tested lipases exhibited different degree of substrate specificity towards EPA and DHA, omega‐3 acids not present in natural seed oils. Thus, CAL‐B seems to be the most suitable lipase to produce high content EPA and DHA enriched STAGs from camelina oil as new food ingredients for nutraceutical applications.
