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. 展开更多
