00925njm 22002777a 4500 dc Palacios Santamaría, David author Busto Núñez, Mª Dolores author Albillos García, Silvia María author Ortega Santamaría, Natividad author 2022-01 Monoacylglycerols (MAG) containing polyunsaturated fatty acids (PUFA) have been synthesized by glycerolysis of anchovy oil using Lipozyme RM-IM in a solvent-free system. The experimental conditions, reaction temperature, substrate molar ratio (glycerol/triacylglycerol, Gly/TAG) and enzyme concentration were studied. A response surface methodology was employed to analyze the effect of the individual variables on MAG production and oxidative stability with respect to induction time. The operating conditions that simultaneously optimized MAG yields and oxidative stability were a reaction temperature of 40 °C, a Gly/TAG molar ratio of 2:1 and 6% enzyme load. The yield obtained was 20.34% of MAG (with 12.12% of 2-MAG) and an induction time of 1.88 h. 0023-6438 http://hdl.handle.net/10259/6197 10.1016/j.lwt.2021.112600 Desirability function Lipase-catalyzed glycerolysis Monoacylglycerols Oxidative stability Polyunsaturated fatty acids Synthesis and oxidative stability of monoacylglycerols containing polyunsaturated fatty acids by enzymatic glycerolysis in a solvent-free system
