ABSTRACT: In this paper we report a biocatalytic approach for the efficient synthesis of anisyl propionate by direct esterification of anisyl alcohol with propionic acid mediated by commercially available Novozym 435, in presence of molecular sieves which serves for the efficient removal of water formed in the reaction. Process optimization was performed regarding the optimal solvent (2-methyltetrahydrofuran), temperature (60 ˚C), and molecular sieves load (100 mg/mL). Further scaling-ups were performed under optimal conditions increasing the substrates concentration up to 1000 mM with unaltered conversions in anisyl propionate (>95 % after 6 hours reaction time).
Key words: lipase, aroma, flavor, biocatalysis, esterification, green solvent
