Passion fruit juice has rich aroma of various fruits, and it is possible to establish more comprehensive conditions for gas chromatography-mass spectrometry. The main components of 14 types of aroma from passion fruit juice were determined by gas chromatography-olfactometry-mass spectrometry (GC-O-MS), and the main aroma components under different extraction conditions were analyzed by head space-solid phase micro-extraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS). Through experimental analysis, the conditions was as follows: passion fruit juice without NaCl 0.5 mL, extraction fiber 65 μm DVB/PDMS, extraction temperature 40 ℃, extraction time 20 min, desorption time 5 min. Sixty-two volatile components were determined, including esters, alcohols, alkenes and ketones, and the esters (71.58%), which dominated the aroma of passion fruit juice, this method was effective and feasible.

Key words: passion fruit, head space-solid phase micro-extraction-gas chromatography-mass spectrometry (HS-SPME- GC-MS), volatile aroma components, gas chromatography-olfactometry-mass spectrometry (GC-O-MS)
