dc.description.abstract | The postharvest evolution of Penjar tomatoes has been studied in four accessions representative of the variability of the varietal type. The long-term shelf life of these materials, which carry the alc allele, was confirmed with 31.2–59.1% of commercial fruits after 6 months of effective conservation at room temperature and a limited loss of weight (21.1–27.9%). Aroma in Penjar tomatoes is differentiated from other tomato varieties by a characteristic ‘sharp-floral’ aroma descriptor. The evolution of the ‘sharp-floral’ aroma during postharvest showed a peak of intensity at 2 months of postharvest, though in one accession a delay of 2 months in this response was detected. Out of 25 volatiles analysed, including main and background notes, a reverse iPLS variable selection revealed that the main candidates behind this aromatic behaviour are α-terpineol, trans-2-hexenal, 6-methyl-5-hepten-2-one, trans-2-octenal, α-pinene, β-ionone, 2 + 3-methylbutanol and phenylacetaldehyde. Between harvest and 2 months postharvest, most compounds reduced considerably their concentration, while the intensity of the ‘sharp-floral’ descriptor increased, which means that probably there is a rearrangement of the relative concentrations among volatiles that may lead to masking/unmasking processes | ca_CA |
