Physicochemical characterization of different tomato commercial cultivars grown in Iran

The purpose of the present research was to investigate four commercial cultivars of tomato (Karoon, 3402, LS0019 and H1015) in order to determine the physicochemical attributes of the cultivar. During this investigation, fruit qualities were evaluated: Soluble solids, total solids, and moisture, pH, lycopene, β-carotene, lutein, and β-cryptoxanthin contents, color indexes (CIE a* b* L*), hue angle (h), chroma (C), total polyphenols and antioxidant activity.The amounts of total solids, a*, b*, L*, carotenoids (lycopene, β-carotene, lutein, β-cryptoxanthin), total polyphenols, and antioxidant activity (Free radical scavenging capacity, reducing power, total antioxidant capacity) remained significantly different among the investigated cultivars (p<0.05). The results showed that the H1015 cultivar had the highest antioxidant activity and carotenoids content especially lycopene. Moreover, this cultivar had the best color indexes (highest a*) in comparison with the other cultivars, it is concluded that the H1015 cultivar is comparable to other cultivars and thus is recommended for cultivation and processing.
