Interpretive Summary:

Technical Abstract: Important volatile compounds contributing to the aroma of fresh tomatoes were determined and identified using gas chromatography-olfactometry (GC-O) and gas chromatography-mass spectrometry (GC-MS) techniques. Three panelists sniffed the aroma volatiles on the GC-sniff, as the compounds were being eluted. Aromas were detected from a total of 24 compounds. Out tof these, 14 compounds have been previously identified as important contributors to fresh tomato aroma. These compounds are: 3-methylbutanal, 1-penten-3-one, hexanal, cis-3-hexenal, trans-2-hexenal, cis-3-hexenol, trans-2-heptenal, 1-octen-3-one, 6-methyl-5-hepten-3-one, 2- isobutylthiazole, phenylacetaldehyde, 2-phenylethanol, geranylacetone and B-ionone. The remaining 10 compounds appear to contribute to fresh tomato aroma and were analyzed by GC-MS. Their aroma descriptors ranged from pungent, rancid and medicinal to fruity, green and caramel-like.
