Summary

Volatile carbonyl compounds of arctic brambles at various stages of ripeness were analyzed as their 2,4-DNPH's by a combined TLC-GLC-MS method. Twenty-one different carbonyl compounds could be identified. During the ripening process the content of most carbonyl compounds increased, the largest changes occuring in the amounts of acetaldehyde, pentenal, acetone, acetonn and diacetyl but the content of hexenal decreased.

Zusammenfassung

Die leichtflüchtigen Carbonylverbindungen der Brombeere wurden in verschiedenen Stufen der Reife als 2,4-DNPH mit der kombinierten DC-GC-MS-Methode analysiert. 21 verschiedene Carbonylverbindungen wurden entdeckt. Während des Reifens vermehrte sich die Quantität der meisten Carbonylverbindungen; die größten Veränderungen geschahen in der Menge des Acetaldehyds, Pentenals, Acetons, Acetons und Diacetyls. Der Gehalt an Hexenal verminderte sich.
