The aroma volatile compounds in Fuji apple were isolated by solid-phase microextraction( SPME),and detected by gas chromatography-mass spectrometry( GC-MS). The results showed that the optimal retention time of the heating up of capillary columns was 5 min. Of the seven fibers used in this work,DVB/CAR/PDMS was found to be the most suitable to extract the aroma volatile compounds in Fuji apple. A total number of 43 volatile compounds were identified according to their retention time on capillary columns and their mass spectra,including eleven esters,ten alcohols,ten aldehydes,seven alkenes,two anhydrides,one ketone,one phenol and one ether. This detection method will provide a new foundation for analysis of volatile compounds in apple were identified.

Solid-phase and micro-extraction combined with GC/MS(SPME-GC-MS) were employed to detect main aroma components in ‘Changping 8’ apple fruit. The results showed that, 29 kinds of compounds were identified from the aroma components in ‘Changping 8’ apple fruit, and they were aldehydes, alcohols, esters, ketones, etc. The main aroma components of apple fruits were acetic acid, hexyl ester, acetic acid, butyl ester,(E)-2-hexenal, 1-butanol, hexanal, and 1-hexanol.
