摘　　要：目的:优选咖啡渣中脂肪酸的提取工艺。方法:以提取物中总脂肪酸的得率为指标,通过正交试验法优化脂肪酸的提取工艺参数。结果:最佳提取工艺为8倍量的丙酮提取3次,每次3 h,所得脂肪酸得率为17.06%。结论:优选的工艺提取效率高、结果稳定,为咖啡渣中脂肪酸类成分的工业化生产提供参考。Objective： To optimize the best of fatty acids extraction methods from coffee residue. Methods： The best extraction method was investigated using the yields of total fatty acids and optimized through orthogonal test design. Results： The conditions with highest fatty acids yield were obtained as follows： the extraction solvent was acetone, the ratio of material-solvent was set 18 （m/v）, extracting for 3 times with 3 hour each time. Under these conditions the yield of total fatty acids can reach 17. 06% （g/g）. Conclusion： The optimized extraction method was high efficiency and stable, can provide some reference for the industrialization of fatty acids in coffee residue.
