Improving enzymatic production of diglycerides by engineering binary ionic liquid medium system.

摘要: The tunable property of ionic liquids (ILs) offers tremendous opportunity to rethink the strategy current efforts resolve technical challenges that occurred in many production approaches. To establish an efficient glycerolysis approach for enzymatic diglycerides (DG), this work reported a novel concept improve DG yield by applying binary IL system consisted one with better selectivity and another being able achieve higher conversion triglycerides (TG). candidates combination were determined individually examining lipase-catalyzed different ILs, as result, promising ones are divided into two groups based on their reaction specificities. effects parametric variables then preliminarily evaluated, following further investigation performance systems from cross-group combinations. TOMA.Tf 2 N/Ammoeng 102 was employed optimization Response Surface Methodology. Eighty eighty-five percent (mol%) oil up 90% total (73%, wt%) obtained, which markedly than those previously reported. This demonstrated practical feasibility couple advantage (high TG high selective work) individual ILs over-perform reaction. It is believed could be also applicable other establishment more protocols.
