Abstract
Patatin, a lipase obtainable from potatoes, has been found to have advantages in the esterification reaction of fatty acids to yield fatty acid alkyl esters. Methods for application of this lipase activity are described, as well as the use of patatin in various industrial processes.
Claims5
A method for selectively preparing a fatty acid alkyl ester comprising:
- providing a liquid reaction medium comprising a fatty acid feedstock, said fatty acid feedstock comprising one or more C4-C26 fatty acids and at least 6 g/L free fatty acids, said liquid reaction medium further comprising one or more C1-C3 alcohols and an effective amount of native patatin;
- and
- allowing the one or more fatty acids in the liquid reaction medium to react with the native patatin and the one or more C1-C3 alcohols to obtain the fatty acid alkyl ester,
- wherein the native patatin is present in said liquid reaction medium in a dissolved or a dispersed form, wherein said liquid reaction medium is an organic medium having a water content below 50% by volume, and wherein the alcohol is at least one C1-C3 monohydroxyalcohol.
