The method of liquid-liquid extraction is used to recovery the ethyl maltol from the crystal-lization mother liquor. The effect of solvent type, proportion, extraction time and temperature on extraction ef-ficiency were discussed. The results showed that chloroform was the extraction agent. The optimum extraction process were as follows: the volume ratio of extracting agent and mother liquor was 1:1, extraction time was 60 min , extraction temperature was 20 ℃. The ethyl malt content was analyzed by HPLC, and its extraction efficiency was 99.73%.
