Title
Continuous production of monoacylglycerols from palm olein in packed-bed reactor with immobilized lipase PS
Abstract

A packed-bed reactor (PBR) system using immobilized lipase PS as biocatalyst was developed for continuous monoacylglycerols (MAG) production. The condition for continuous MAG production using immobilized lipase PS (IM-PS) of 1.5 g (550 U) in PBR (0.68 cm i.d., 25 cm long) was optimized. The effect of molar ratio of glycerol to palm olein, water content in glycerol and residence time on MAG production was investigated. The optimal glycerol to palm olein molar ratio and water content in glycerol were 12:1 and 10% (w/w), respectively. The yield of MAG increased with increasing residence time. At a residence time of 7.5 h gave the highest yield of MAG of 60%. The long-term operation gave the highest yield of MAG 61.5% at 24 h of the operation time with the productivity of 1.61 g MAG/day. A half-life of the long-term process was 35 days of the operation time with the productivity of 0.81 g MAG/day. Furthermore, the large scale of MAG production was performed continuously with IM-PS of 15 g (5500 U) in PBR (1.5 cm i.d., 50 cm long). The highest yield of MAG in large-scale operation of 70.1% and the 11-fold increasing in productivity of 18.3 g MAG/day were obtained at 24 h of the operation time.
