    • A process for the preparation of an ester of formula (I), wherein R is the carbon residue of a polyol; R 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.
    • 一种制备式(I)酯的方法,其中R是多元醇的碳残基; R 1选自3至30个碳原子的直链或支链烷基或羟基烷基; 具有3至30个碳原子的直链或支链烯基或羟基烯基; 烷; 芳; 芳基; 5至7个碳原子的环烷基及其混合物; n为1至多元醇上的可置换羟基的总数; r为0或等于未酯化的OH基团的总数; n + r等于多元醇中可置换的OH基团的总数。 该方法包括使酸与氯甲酸烷基酯在100%水的水性介质中接触以形成酸酐,然后使所述酸酐与多元醇接触以形成所述酯。 还公开了包含可食用基础材料和非营养酯的食品组合物。
