Interpretive Summary: This study provides strong evidence that a methyl salicylate fumigation prior to storage alleviated chilling temperature (5 °C) caused flavor loss in tomatoes. The technology is useful to the tomato industry which suffers decay loss when tomato storage/transportation temperature is high, on the other hand, suffers flavor loss when the temperature is low.
Technical Abstract: Tomato fruits exposed to chilling temperatures suffer aroma loss prior to visual chilling injury (CI) symptoms. Methyl salicylate (MeSA) and methyl jasmonate (MeJA) treatments were reported to alleviate the development of visual CI, however, it is unknown if the treatments alleviate internal CI in the form of aroma loss. In this research, ‘FL 47’ tomatoes at breaker stage were treated with MeSA or MeJA vapor prior to chillingexposure to chilling temperature. The chilling treatment did not result in visual CI; however, for internal CI it generally suppressed production of oxygen-containing heterocyclic compounds, ketones, sulfur- and nitrogen-containing heterocyclic compounds, alcohols, and aldehydes, including 13 important aroma contributors to tomato fruit. MeJA had no impact on sensory evaluation in spite of resulting in slightly altered volatile profile, however, MeSA alleviated the CI-induced reduction of a number of volatile compounds, and thereby enhanced tomato aroma.
