Attention is focused on the oxidative stability of the reaction products, determined in terms of induction time (It). The effects of glycerol/triacylglycerol molar ratio, enzyme concentration, and reaction temperature on mono- and diacylglycerol production and It are all assessed. The operating conditions that optimized monoacylglycerol yields and oxidative stability were a glycerol/triacylglycerol ratio of 3/1, 9.0% (w/w) Lipase PS-DI, a stirring rate of 200 rpm, and a reaction time of 4 h, at 45.8 °C, producing a content of 24.8% and 51.9% of mono- and diacylglycerols, respectively, over an It of 1.41 h. The glycerolysis conditions determined by simultaneous optimization strategy increased the oxidative stability of the glycerolysis products by 68%, which rose from 0.84 h (individual optimization) to 1.41 h. application/pdf eng Elsevier Food Chemistry. 2019, V. 271, p. 372-379 https://doi.org/10.1016/j.foodchem.2018.07.184 Attribution-NonCommercial-NoDerivatives 4.0 Internacional http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Lipase PS-DI Monoacylglycerols (MAG) Oxidative stability Polyunsaturated fatty acids (PUFA) Solvent-free glycerolysis Bioquímica Alimentos Biotecnología Biochemistry Food Biotechnology Lipase-catalyzed glycerolysis of anchovy oil in a solvent-free system: Simultaneous optimization of monoacylglycerol synthesis and end-product oxidative stability info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Food Chemistry 271 372 379 THUMBNAIL Palacios-fc_2019.pdf.jpg Palacios-fc_2019.pdf.jpg IM Thumbnail image/jpeg 4540 https://riubu.ubu.es/bitstream/10259/9762/10/Palacios-fc_2019.pdf.jpg e09cf86b1dfe19eb138202940fbac82c MD5 10 Palacios-fc_2019-Fig_1.pdf.jpg Palacios-fc_2019-Fig_1.pdf.jpg IM Thumbnail image/jpeg 4739 https://riubu.ubu.es/bitstream/10259/9762/11/Palacios-fc_2019-Fig_1.pdf.jpg 522b19fa7f3020ec29586b0df2a6e8d3 MD5 11 Palacios-fc_2019-Fig_2.pdf.jpg Palacios-fc_2019-Fig_2.pdf.jpg IM Thumbnail image/jpeg 4299 https://riubu.ubu.es/bitstream/10259/9762/12/Palacios-fc_2019-Fig_2.pdf.jpg 63a20291c6e2f2427c453902636c4f67 MD5 12 Palacios-fc_2019-Fig_3.pdf.jpg Palacios-fc_2019-Fig_3.pdf.jpg IM Thumbnail image/jpeg 4178 https://riubu.ubu.es/bitstream/10259/9762/13/Palacios-fc_2019-Fig_3.pdf.jpg 9fcbc3b5cb3f489c0c91c1b11ebc1553 MD5 13 Palacios-fc_2019-Table_1.pdf.jpg Palacios-fc_2019-Table_1.pdf.jpg IM Thumbnail image/jpeg 3409 https://riubu.ubu.es/bitstream/10259/9762/14/Palacios-fc_2019-Table_1.pdf.jpg 8aa6b691840b0cd1db2bbbbb46e3a058 MD5 14 Palacios-fc_2019-Table_2.pdf.jpg Palacios-fc_2019-Table_2.pdf.jpg IM Thumbnail image/jpeg 3351 https://riubu.ubu.es/bitstream/10259/9762/15/Palacios-fc_2019-Table_2.pdf.jpg 2e513269be61fca0f2d2532ac4b99653 MD5 15 Palacios-fc_2019-Table-3.pdf.jpg Palacios-fc_2019-Table-3.pdf.jpg IM Thumbnail image/jpeg 3214 https://riubu.ubu.es/bitstream/10259/9762/16/Palacios-fc_2019-Table-3.pdf.jpg b606d6db7a2a16a9fb5c4d7b26c30e19 MD5 16 LICENSE license.txt license.txt text/plain;
