Compositional analyses of flavour compounds in fresh and processed fruits are often of limited value because it is clear that compounds with very low aroma thresholds can have dominant effects upon fruit flavour. Moreover after processing, the compounds with the primary influence on flavour may change. Quantification of individual aroma compounds is also problematic requiring high resolution gas chromatographs linked to ion-trap or related detectors (HRGC/MS) although flame-ionisation detection is often more convenient.

Automated Procedures At least four commercial automated instruments exist which will concentrate headspace volatiles on adsorbents and thermally desorb them into a gas chromatograph. Times, temperatures, and gas flow rates are accurately controlled. Manual handling steps which can introduce variability are eliminated. Since these instruments are automated, sample throughput is enhanced they can be interfaced to high resolution gas chromatographs. [Pg.43]

The chemical composition of either olefins is an extremely complex mixtnre of predominately 9 or 12 carbon atom olefins, respectively. Indeed, high-resolution gas chromatographic analysis of p-nonylphenol has achieved resolution of 22 distinct para isomers, each alkene moiety identified as being a distinct and different configuration of the compound described for simplicity as propylene trimer or nonene. Although such an exhaustive study has not yet been condncted on p-dodecyl phenol, results would be expected to be at least as, if not more, complex. [Pg.65]
