Abstract:
A sustainable development should turn the large amount of waste produced by the food industry into raw material for other processes. As a residue of tomato industry, the peels can be exploited for the recovery of functional substances or as a substrate in anaerobic digestion or, in perspective, in a possible joint application of both. Aim of the work was to characterize the peels of new tomato lines (with red, orange, pink, black-red and dark-red fruit), for the content of bioactive substances and for some parameters linked to no-food use: chlorophyll, polyphenols and carotenoids content, energy value, theoretical biochemical methane potential (TBMP) through stochiometric method. The peel color mirrored a different content of the bioactive substances: the dark-red fruits showed a significant increase of the carotenoids content, while the peel of the black-red fruits had the highest values of polyphenols. The preferential accumulation of functional compounds influenced the values of the other parameters. The low heating value resulted lower in the variants respect to the control (red fruits) and the percentage of C and H was significantly higher in the red, dark-red and pink fruits. This in turn led to a substantial difference in the estimation of the TBMP.
