An isolation and identification of volatile components in tempe for 2, 5 and 8 days fermentation by simultaneous distillation-extraction method was carried out. Simultaneous distilallation-extraction apparatus was modified by Muchalal from the basic Likens-Nickerson's design. Steam distillation and benzena as an extraction solvent was used in this system. The isolation was continuosly carried out for 3 hours which maximum water temperature in the Liebig condenser was 8°C. The extract was concentrated by freeze concentration method, and the volatile components were analyzed and identified by combinied gas chromatography-mass spectrophotometry (GC-MS). The Muchalal's simultaneous distillation extraction apparatus have some disadvantage in cold finger condenser, and it's extractor did not have condenser. At least 47, 13 and 5 volatile components was found in 2, 5 and 8 days fermentation, respectively. The volatile components in the 2 days fermentation were nonalal, a-pinene, 2,4-decadienal, 5-phenyldecane, 5- phenylundecane, 4-phenylundecane, 5-phenyldodecane, 4-phenyldodecane, 3-phenyldodecane, 2-phenyldodecane, 5-phenyltridecane, and caryophyllene
