Abstract
4. Conclusions
The volatile profile of dry cherry tomatoes was affected in a different ways, depending on processing conditions. Microwave energy modified the volatile fraction of fresh tomato, developing a new profile, mainly due to both furfural generation and activation of Maillard reactions. Osmotic pretreatment in a sucrose solution, followed by hot-air-drying, was the combination of drying techniques that mainly preserved the typical aroma of fresh cherry tomato. Finally, principal component analysis (PCA) confirmed the possibility of obtaining dried cherry tomatoes with different volatile profiles either by microwave power or the application of hot air-drying.
