Abstract :
Expression of dissatisfaction with tomato aroma prompted us to lead this study on the impact of domestic storage conditions on volatile compounds. orage modalities (20 and 4 °C) and two cultivars (Levovil and LCx) were used. Volatile compounds were analysed by gas chromatography–mass spectrometry detection after accelerated solvent extraction. Physical characteristics, lipoxygenase activity, hydroperoxide lyase activity; linoleic acid and linolenic acid were monitored. g tomatoes at 4 °C induced a drastic loss in volatiles, whatever their biosynthetic origin. After 30 days at 4 °C, the concentration of volatiles had decreased by 66%. Reconditioning for 24 h at 20 °C was able to recover some aroma production after up to 6 days storage at 4 °C. Volatile degradation products arising from carotenoids and amino acids increased when tomatoes were kept at 20 °C, while lipid degradation products did not vary. g tomatoes at fridge temperature, even for short durations, was detrimental for their aroma. This should be taken into account to formulate practical advice for consumers.
