ABSTRACT:
The invention relates to a process for the enzymatic preparation of regioselective fatty acid esters of ascorbic acid and selected fatty acid alkyl esters.
Ascorbic acid and fatty acid alkyl esters are reacted in a solvent or suspending agent at reduced pressure in relation to the atmosphere and temperatures above the boiling point of the resulting alcohol of reaction.
