Abstract: Esterification and transesterification catalyzed by porcine pancreatic lipase in organic solvents are studied. The activity of lipase is dependent upon the pHof powdered lipase, the nature of organic solvents, temperature, water content, carbon chain length and branch of substrates. In addition, a rose-fragrant terpene alcohol ester was produced by using lipase with geraniol and carboxylic acid(lauric or octanoic acid).

Key words: Lipase, Esterification, Transesterification
