| Abstract:
The quality of the processing tomato final products expressed by flavour, colour, and taste, is directly correlated with fresh tomato fruit characteristics. This is also true for the components like lycopene and anthocyanines. Twenty hybrids and varieties of processing tomatoes, recently introduced in Tunisia, grown in experimental trial during the 2004/2005 season in the north east of the country were evaluated for several qualitative and technological characteristics: Brix, pH, total acidity, sugars, lycopene and anthocyanines. The results show, for some characteristics, significant differences between the investigated varieties, these results may help manufacturers to select appropriate varieties for the desired processed products. The best 5 cultivars found are: TKE 58, Perfectpeel, TS 15, Hypeel 303, and EX02530438. | |
