Abstract

Mono and diacylglycerol is one of oil diversification products that its economics value is higher and its market prospect is brighter in this globalization era. The purpose of this research is to produce mono and diacylglycerol from Refined, Bleached, Deodorized Palm Oil by using waste egg shell as catalyst. Waste egg shell was calcined at temperatur 70oC and time 2 hours to forming active CaO as catalyst. Then the process continued with glycerolysis process. Glycerolysis process produced mono and diacylglyserol. Then mono and diacylglycerol was separated by using separator fannel. Then the upper layer was vaporated to separate mono and diacylglycerol from tert-butanol. Effect of various varible process such as amount of catalyst and glycerolysis time was observed in this research. The best result was at temperature 70oC, co-solvent and oil rasio 3:1 (v/b), reaction time 2 hours, and catalyst amount 4% from oil with maksimum purity 68,61%. Mono and diacylglycerol formed in this reasearh is w/o emulsifier with HLB 5,19. The result of this research showed that waste egg shell is suitable to be used as the source of cheap catalyst to produce mono and diacylglycerol.

Abstract

Mono and diacylglycerol (MDAG) is one of the synthetic emulsifier agent widely used in food industry. Emulsifier agent is one of the economically high value oleochemical product. The purpose of this research is to produce MDAG through glycerolysis process of refined bleached deodorize palm oil (RBDPO) and glycerol by using egg shell waste as catalyst (4 % of oil weight) for 2 hours, whereas the variables ratio of tert-butanol to oil (1, 2, 3 v/w) and reaction temperatur (60, 70 and 80 oC). Egg shell waste was calcined at 900 oC for 2 hours to form active CaO catalyst. Then glycerolysis process to produce mono and diacylglyserol. Mono and diacylglycerol that formed was separated by using separator fannel. The upper layer was vaporated to separate MDAG from tert-butanol. The content of MDAG was analyzed using Gas Chromatography. The best result was at 70 oC temperature, ratio co-solvent to oil 3:1 (v/w), 2 hours of reaction time and 4% of catalyst amount from oil and oil molar ratio to glycerol 1:6 with MDAG content of 68,62%. MDAG formed are w/o emulsifier with 5.19 HLB. The result of this research shows that egg shell waste is suitable to be used as source of cheap catalyst to produce mono and diacylglycerol.
