Cover Story: Tomato is one of the main vegetable crops, with about 1/4 of the yearly production dispatched to the processing industry. The detailed metabolic profile of processed tomatoes is currently missing. The goal of this investigation was to provide a qualitative picture of commercial tomato purees representative of the Italian market with a more sustainable analytical approach based on a single extraction protocol with green solvent and one-shot analysis. More than 500 features were detected and assigned. The results not only confirmed the persistence in processed tomatoes of the main metabolites already reported in fresh fruits but also provided new insights into specific components never traced before in similar finished samples. Multiple bioactive compounds, reported here, promote the relevance of transformed tomatoes for a healthy diet. View this paper
