大気圧コロナ放電イオン化質量分析によるリンゴ発散香気成分のプロファイリング

Apples are the world's largest fruit in both production and consumption, and their fresh aroma is one of the reasons for their popularity. Apple aroma compounds have been studied previously, but all methods have problems such as long measurement time or processing. In this study, volatile compounds emitted from intact apples were analyzed using an atmospheric pressure corona discharge ionization (APCDI) method combined with collision-induced dissociation mass spectrometry, which require no pretreatment and short measurement time. Apples measured were Fuji, Gala, Akane, Sansa, Jonagold, Golden Delicious, Jonathan, Tsugaru, and Orin. Detected major ion peaks were protonated molecules of saturated esters [C_xH_2xO₂+H]⁺ (x=2-12) for all the apples. The distribution of ester isomers for each C_xH_2xO₂ depends upon apple cultivars. For example, the relative intensities at R₁=C₄H₉ were large in Fuji, but small in Sansa. This is an indication of specificity among varieties.
