【 摘 要 】

Free Fatty acidresulting from hydrolisis ofvarious types of oil enzymatically has been great interest recently to save energy, in other handthat the product are environmentally friendly.Lipases as biocatalysts for synthesis reactionswillbedissolved with the product, making difficult their reuse. Efficiency can be done with the use of enzyme immobilization, which can be used for repeated reaction. The products of free fatty acids from coconut oil by hydrolysis of lipase can be used as a natural substrate for making flavorthat can be consumed and safe for health. The effect of free lipase andimmobilization of lipase on hydrolisiswere studied. Reaction time of hydrolisis was varied as 30, 60, 90, 120 and 150 minutes. Thevariationof concentration of lipaseaddition was 4, 5, 6, 7 and 8 % .The types of treatment were used in this research free lipase and the immobilized lipase. The results shows that the highest conversion on hydrolisis of coconut oilby using free lipase treatmentwas performed by 6 % of lipase additionwith reaction time 60 minutes that are 52,31%. While, the highest conversion on hydrolisis of coconut oil by using the immobilized lipase was shownby 8% of lipase addition with reaction time 120 minutes that is 56,01%.The results of the hydrolysis process in the form of fatty acid was used as the base material esterification process resulting ester product (natural flavor). Ester yield was produced by free lipase esterification was 28,21 and 32,14 % in immobilizedlipaseesterification.
