Production and Concentration of Monoacylglycerols Rich in Omega-3 Polyunsaturated Fatty Acids by Enzymatic Glycerolysis and Molecular Distillation
2020Co-Authors: Angela Garcia Solaesa, Maria Teresa Sanz, Mia Falkeborg, Sagrario Beltran, Z GuoAbstract:Production and concentration of monoacylglycerols rich in omega-3 polyunsaturated fatty acids by enzymatic glycerolysis and molecular distillation (2016) Food Chemistry, 190, art. no. 17743, pp. 960-967 Abstract Production of monoacylglycerol (MAG) concentrate rich in omega 3 polyunsaturated fatty acids (n-3 PUFAs) was conducted through short path distillation (SPD) of an acylglyceride mixture produced by enzymatic glycerolysis. 67% yield of MAG was achieved in 2 h using sardine oil in a mole ratio of 1:3 with glycerol and 5% of immobilized Candida antarctica lipase B (Lipozyme 435) in tert-pentanol medium. For industrial interest and preservation of stability of the components, SPD under vacuum of 10 -3 mbar was used as an appropriate approach for fractionation of MAG operated in a UIC KDL 5 system. A stepwise SPD process was designed: the first distillation at evaporator temperature (T E ) of 110ºC was performed to remove completely the glycerol and most of FFA; and the second distillation at optimized T E 155ºC with feeding flow 1.0 mL/min; resulting in a stream distillate with MAG purity of 91% and 94% overall recovery of MAG. This work also demonstrated that SPD is able to concentrate n-3 PUFA in MAG form by distilling at proper T E e.g. 125ºC, where n-3 PUFAs will be concentrated in the residues. Moreover, this work mapped out a complete processing diagram for scalable production of n-3 PUFAs enriched MAG as potential Food Emulsifier and ingredient

production and concentration of monoacylglycerols rich in omega 3 polyunsaturated fatty acids by enzymatic glycerolysis and molecular distillation
Food Chemistry, 2016Co-Authors: Angela Garcia Solaesa, Maria Teresa Sanz, Mia Falkeborg, Sagrario BeltranAbstract:Abstract Production of monoacylglycerols (MAGs) rich in ω-3 polyunsaturated fatty acids ( n -3 PUFAs) was conducted through short path distillation (SPD) of an acylglycerol mixture (containing 67% MAGs) produced by enzymatic glycerolysis of sardine oil with glycerol. A stepwise SPD process in a UIC KDL 5 system (vacuum 10 −3 mbar, feeding flow 1.0 mL/min) was proceeded: the first distillation performed at evaporator temperature ( T E ) of 110 °C to remove glycerol completely and most of FFAs; and the second distillation at optimized T E 155 °C; resulting in a stream distillate with 91% purity and 94% overall recovery of MAGs.

optimisation and economic assessment of lipase catalysed production of monoesters using rhizomucor miehei lipase in a solvent free system
Journal of Cleaner Production, 2016Co-Authors: Ahmad Mustafa, Amin Karmali, Wael AbdelmoezAbstract:Abstract Enzymatic production of glycerin monolaurate (GML) was carried out by lipase catalysed esterification of lauric acid and glycerin in a solvent-free media. Response surface methodology (RSM), based on 5-level and 3-variable composite design, was employed to study the interactive effects of reaction temperature (48–60 °C), enzyme load (1–4% w/w), and glycerin to lauric acid molar ratio (1:1–4:1) on glycerin laurate yield. The optimum conditions obtained were a temperature of 60 °C, an enzyme load of 4%, and a glycerin to lauric acid molar ratio of 4:1. The maximum predicted and experimental conversion values were 92.26% and 93.23%, respectively. Utilisation of Lipozyme RM IM (Rhizomucor miehei lipase) allowed the formation of a mixture consisting of 50% monoglyceride, 34.6% diglyceride and 8.4% triglyceride, which fulfills the requirements established by the World Health Organization (WHO) for use as a Food Emulsifier. In addition, the Lipozyme RM IM maintained more than 90% of its original activity after being used for six cycles. Finally, an economic study was performed to interrogate the feasibility of the proposed enzymatic manufacturing process. The obtained results were compared with the traditional catalysed chemical process. The economic feasibility study revealed that the needed amount of Lipozyme RM IM was 2.5 kg/t of feedstock. The high conversion achieved in a short reaction time (1 h), as well as the proven operational stability of Lipozyme RM IM, revealed a promising potential for this green and sustainable route in practical applications.
