A process for preparing fatty acid esters of saccharides which comprises subjecting at least one saccharide selected from monosaccharides having from 5 to 7 carbon atoms, disaccharides consisting of hexoses, sugar alcohols having from 4 to 6 carbon atoms, ether compounds consisting of monosaccharides having from 5 to 7 carbon atoms and monohydric alcohols, and ether compounds consisting of hexose disaccharides and monohydric alcohols, to reaction with at least one member selected from saturated and unsaturated fatty acids having from 6 to 22 carbon atoms and esters of the above-defined fatty acids and lower alcohols in the presence of an organic solvent by the use of a hydrolase. The organic solvent is at least one member selected from the group consisting of acetylacetone, ethylene carbonate, propylene carbonate, y-butyrolactone and heterocyclic compounds of the following general formula (1)
wherein R represents a linear or branched alkyl group having from 1 to 3 carbon atoms.
一种制备糖类脂肪酸酯的工艺,包括将至少一种选自具有 5 至 7 个碳原子的单糖、由己糖组成的二糖、具有 4 至 6 个碳原子的糖醇、由具有 5 至 7 个碳原子的单糖和一元醇组成的醚化合物以及由己糖二糖和一元醇组成的醚化合物的糖类与至少一种选自具有 6 至 22 个碳原子的饱和及不饱和脂肪酸的酯反应、以及由六糖二糖和一元醇组成的醚类化合物,在有机溶剂存在下,通过使用水解酶,与至少一种选自具有 6 至 22 个碳原子的饱和及不饱和脂肪酸以及上述脂肪酸和低级醇的酯类化合物发生反应。有机溶剂至少是选自乙酰丙酮、碳酸乙烯酯、碳酸丙烯酯、丁内酯和以下通式 (1) 的杂环化合物组成的组中的一个成员
其中 R 代表具有 1 至 3 个碳原子的直链或支链烷基。
