Abstract
Aliphatic, saturated or unsaturated, straight or branched chain C2-C24 monocarboxylic acids and polyhydric alcohols, particularly glycerol are selectively reached to monoesters in the presence of an enzyme which comprises potato lipid acyl hydrolase. The process can be used too for upgrading technical monoglycerides which contain free fatty acids.
Claims1
A process for deacidification of a monoglyceride containing free C2-C24 monocarboxylic acid as impurity which comprises contacting said monoglyceride with glycerol and a catalytic amount of patatin at a temperature of from 25° C. to 50° C. whereby said free acid is removed by esterification of the acid with said glycerol.
