Ultrasound application is a method of enhancing the performance of biocatalysts. Enzymes performance is strongly influenced by the nature of the reaction medium. Ultrasounds have the potential to significantly influence the activity of the enzymatic processes, provided that the energy input is not too high to inactivate the enzyme. In the present paper a systematic study on ultrasound-assisted enzymatic esterification for aroma esters preparation is described. Thus, by ultrasound assisted enzymatic esterification i-amyl acetate was obtained. The method is efficient, mild, and environmentally benign. Significant improvements were obtained in comparison to conventional method. The results show a favourable perspective of the ultrasound technique to improve the process efficiency and reduce the reaction time. The commercial aroma esters synthesis will be potentially realized due to this ultrasound-promoted esters synthesis method.
