N2 - The quantitative and enantiomeric distribution of γ-lactones in certain fruits (strawberry, raspberry, pineapple, passion fruit, plum and coconut) compared with corresponding fruit concentrates and beverages was determined by multi-dimensional gas chromatography mass spectometry with an achiral-chiral column combination. It was found that significant variations in enantiomeric excess values of γ-lactones due to varieties and processing influences can occur. On-line multidimensional gas chromatographic-isotope ratio mass spectrometric 13C/12Cisotope ratio measurements of γ-decalactone in vinous beverages and references (synthetic and microbial) were performed, in order to establish how far enantiomeric data in combination with additional δ13c values can serve as a basis for the validation of the genuineness of flavours and flavoured products.
