Lipase-mediated production of specific lipids with improved biological and physicochemical properties

The use of lipases in the modification of lipids has grown significantly in recent years. This increased interest is mainly due to the ability of these enzymes to catalyze the production of lipids with specific distributions of fatty acids that better fit the current needs of consumers, who are looking for healthier foods that are manufactured with the highest quality. The successful use of lipases to obtain modified lipids with low caloric content, high concentrations of n?3 fatty acids or high amounts of phenolic compounds demonstrate the great potential of these enzymes. The lipase-catalyzed production of lipids with reduced caloric content is made possible by the addition of a medium or a very long chain fatty acid to the triacylglyceride. Diacylglicerols with low caloric content can also be produced using lipases. Due to the deficiency of n?3 fatty acids in the current diet, strategies for the lipase-mediated incorporation of these acids in the TAG have shown promising results. Finally, studies have successfully used lipases for the incorporation of phenolic compounds in the lipid structure, which produce compounds with improved oxidative stability and more beneficial health effects.
