Lipase enzyme (E. C. Triacylglycerol acylhydrolase) is able to catalyse both esterification and hydrolytic reactions. The direction of the equilibrium reaction depends mainly on the conditions used. Biocatalytic esterification of alcohols and acids can be realised in low-water systems. Removing one of the products (water, ester), the equilibrium of the reaction can be shifted towards the reaction, thus production of ester is preferred. Pervaporation can be applied for both purposes. In this work pervaporation was used to remove the ester produced. This way the parameters of the production of natural flavour esters can be assured.
