Investigating test-control paired differences in flavour-molecular correlations

John Castura/ September 25, 2024/ Oral Presentation

We investigate supervised principal component regression (SPCR) its sensory and instrumental results from a data set of eight pinot noir wines. Data include measured concentrations of volatile organic compounds from headspace—solid phase micro-extraction—gas chromatography—mass spectrometry (HS-SPME-GC-MS) and sensory descriptive analysis results on two selected sensory attributes evaluated orthonasally. We show the solution from SPCR as conducted conventionally is equivalent to

Do window treatments protect the acceptability for sale of red and white wine?

Light-struck taints in wine develop when they are exposed to sunlight and elevated temperature. Affected wines undergo a colour change, a decrease in fruit flavours and a development of off-flavours that have been described as cooked cabbage and/or corn nuts. This poses a problem in retail stores that have a large number of external facing windows that can potentially expose
