Abstract: The main purpose of this study was to highlight the nutraceutical value of the tomato fruit for five hybrids recently introduced in culture, during the harvesting phases: mature green, half ripen and full ripen: 'Antalya', 'Cemil', 'Lorely', 'Tiger' and 'Sacher'. They differentiate because of their size and fruit colour. The parameters to be followed for each harvest phase were: the chlorophyll a and b content, the total carotenes, the soluble substance, vitamin C, the titratable acidity, and also a maturity index was established. The results obtained showed significant differences between the hybrids, but also during the maturation phases. It singularised Tiger F1 with a total carotene contentof 7.1 (green) to 12.5 (half ripen) and 18.6 mg/100g f.w. (in full ripen) and Sacher F1 with vitamin C from 6.2 (green) to 17.2 (half ripen) and 20.7 mg/100g f.w. (in full ripen). This variability can be attributed to these harvesting phases, but also to the genetic factors, such as cultivar type, fruit size and colour.
