Resumo

Bioaromas can be produced by lipases either through their hydrolytic or (trans)esterifying activities. Therefore, this work reports the development of a lipase-catalyzed biotransformed licuri oil, forming volatile ethyl esters with odor notes resembling tropical fruits. Ethyl octanoate formation was promoted when 7.0 % (m/v) Lipozyme 435 (R) was used to convert a grain alcohol:licuri oil mixture (51:49, v/v) at 58 degrees C and 70 rpm for 6 hours. The biotransformed oil has shown antimicrobial activity against Staphylococcus hominis, S. epidermidis, and Corynebacterium xerosis, bacteria associated with bad skin odor. Finally, this biotransformed oil was used without further treatments (e.g., recovery or purification procedures) to prepare two cosmetic formulations (in a dosage of 1.5 %), aiming for both fragrant and deodorant activity.
