Stereodifferenzierung von γ(δ)-Lactonen und (E)-α-Ionon verschiedener Früchte und ihrer Verarbeitungsprodukte

By means of enantioselective multidimensional gas chromatography (column combination OV 1701/octakis (3-O-butyryl-2,6-di-O-pentyl)-γ-cyclodextrin the simultaneous Stereodifferentiation of theγ- andδ-lactones C₆-C₁₂ was applied to determine the enantiomeric ratios in different fruits and their processed products. In addition (E)-α-ionone was stereodifferentiated in raspberries and products from raspberries. The analysed chiral compounds have characteristic and fruit-specific enantiomeric ratios, which are irrespective of the food processing applied.
