A process for the preparation of an ester of formula (I), wherein R is the carbon residue of a polyol; R<1> is selected from straight or branched chain alkyl or hydroxy alkyl groups of from 3 to 30 carbon atoms; straight or branched chain alkenyl or hydroxy alkenyl of from 3 to 30 carbon atoms; alkaryl; aralkyl; aryl; cycloalkyl of from 5 to 7 carbons and mixtures thereof; n is from 1 to the total number of replaceable hydroxyl groups on the polyol; r is 0 or is equal to the total number of unesterified OH groups; n + r are equal to the total number of replaceable OH groups in the polyol. The process comprises contacting an acid with an alkyl chloroformate in an aqueous medium that is 100 % water to form an anhydride and thereafter contacting said anhydride with a polyol to form said ester. Also disclosed is a foodstuff composition which comprises an edible base material and a non-nutritive ester. |
