Volatile Profiling in Red Wine using ChromSync [AN0032]
With a wide variety of wines available and the consumer market so large, it is vital that wineries test and monitor the volatile compounds, that contribute to the flavour profile, during the production process to ensure that the same flavours are consistently achieved. The volatile compounds that make up the flavour composition must therefore be profiled batch to batch. Strict controls are operated during the production of wine as varying levels of volatiles can vastly affect the flavour of the final product.
Gas chromatography (GC) is often the instrumentation of choice for the analysis of flavour active volatiles in wine. Compass Chromatography Data System (CDS) is a state of the art chromatography software platform that controls GC instruments whilst offering automated processing and reporting of results. ChromSync is an application add on specifically for the flavour and fragrance industry. Chromsync has the ability to determine the ‘fingerprint’ of volatile compounds in wine. The individual ‘fingerprints’ are then compared with a reference standard. ChromSync rapidly compares peak retention time as well as area% profiles of complex chromatograms, making processing volatile flavour profiles effortless. Additionally, ChromSync instantly confirms product batch to batch reproducibility whilst reporting any missing compounds and calculating the degrees of similarity. This application note demonstrated the ease of using ChromSync with CompassCDS for the comparison of six Shiraz red wine samples analysed via headspace (HS) gas chromatography (GC) with flame ionisation detection (FID) and mass spectrometry (MS) for identification of volatile compounds. All samples were made from the same shiraz grape in order to identify both similar and varied volatilesin the wine.
