“…In addition, biocatalysts have lower energy requirements than chemical catalysts and can be used to synthesize products of better quality (3). Lipases (triacylglycerol acylhydrolase EC 3.1.1.3) can be used as biocatalysts for the production of flavor esters by transesterification (3)(4)(5)(6)(7) and direct esteriflcation reactions (8-15}. The use of acetic acid as an acyl donor in transesterification and direct esterification reactions was previously attempted with relatively little or no success (4,5,8,9,12,16-19}.…”

Geranyl acetate is an important flavor and fragrance compound. Two immobilizedCandida antarctica lipases, SP382 and SP435, were investigated for their use in the synthesis of geranyl acetate by direct esterification. Yields between 95 and 99% molar conversion were obtained with 2 and 15% (w/w reactants) of SP435 and SP382 lipases, respectively. Optimum yields were obtained at 0.1M acetic acid and 0.12M geraniol after 16‐h incubation. No inhibitory effect was observed at increasing concentrations of geraniol. Addition of 60% (w/w reactants) water led to 50 and 60% reduction in the esterification activity of SP382 and SP435 lipases, respectively. The best yields were obtained at added water contents between 0–5% (w/w reactants). Solvents with a logP value of 0.85 or more gave reaction yields of more than 80% molar conversion. Higher logP values did not necessarily lead to higher conversion yields. The immobilized lipase SP382 was still active after reusing ten times in the direct esterification reaction.
