Using a controlled maceration device, coupled to an on-line atmospheric pressure ionisation mass spectrometer, the headspace concentrations of volatiles above tomatoes were measured after maceration over a 3-min period. The technique allowed rapid analysis of individual fruit. Tomato fruit were stored under different postharvest treatments (with appropriate control fruit) to mimic typical storage/transport scenarios. After a recovery period in air at ambient temperature, they were macerated to determine the effects of storage on tomato volatile compounds. Storage under nitrogen (35 h) was followed by a recovery period in air (4-6 h)which caused a decrease in C6 volatile compounds and isobutylthiazole, along with an increase in ethanol and acetaldehyde. Storage under low oxygen conditions, followed by a recovery period, had less effect on volatile compounds. Low temperature storage caused a significant decrease in volatile concentrations and the effect was not reversed even after 72 h recovery. Exogenous linolenic acid was added to some treated fruit to determine whether the changes observed were due to a change in lipoxygenase/hydroperoxide lyase activity. The results indicated that cold-stored fruit retained the same enzyme activity as the control fruit whereas the fruit stored at 45C lost enzyme activity.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 18640-74-9 is helpful to your research., Synthetic Route of 18640-74-9
