Abstract

This work studies the mammalian fat acidity reduction, through enzymatic esterification with ethanol for converting FFA into esters. The fat samples collected in a Portuguese company were characterized for their acid value, iodine value, density, kinematic viscosity and moisture content. Four commercial enzymes were tested as catalyst. Lipozyme CALB L contributed to highest acidity reduction. It was selected for the parametric study of the best operating conditions: 45°C of temperature, enzyme/fat and ethanol/FFA mass ratios of respectively0.0060 and 3.25wt/wt, which reduced 67 % the acidity in just one reaction step, after 3 h of reaction time.
