A rational technology for the esterification of fatty acids with ethyl alcohol has been developed, a feature of which is the removal of a reaction by-product (water) by evaporation of an azeotropic mixture of ethyl alcohol - water, the condensate of the latter is dehydrated with zeolites, which allows ethanol to be returned to the reaction zone at a higher concentration, thereby increasing the yield of ethyl esters up to 98%. A rational technology for the enzymatic esterification of fatty acids with high molecular weight alcohols has been developed, which provides a degree of conversion of the starting components to the target product of about 99 %. Such modified fats can be used as confectionery and cooking (deep-frying) fats, respectively, as a safe alternative to traditional specialty fats.
