Abstract :length/fruit width, peel thickness, peel weight, total soluble solids insert ignore into journalissuearticles values(TSS);, pH, titratable acidity insert ignore into journalissuearticles values(TA);, fruit firmness, fruit color and antioxidant activities of the fresh insert ignore into journalissuearticles values(harvest stage); green and yellow insert ignore into journalissuearticles values(ripe stage); fruit pulp of two different cultivar of banana plants insert ignore into journalissuearticles values(Dwarf Cavendish and Gross Michel); cultivated in under protection and organic growing system were determined. At the end of the research, the heaviest insert ignore into journalissuearticles values(170.297 g); and the largest insert ignore into journalissuearticles values(37.059 mm); fruit was obtained from Gross Michel insert ignore into journalissuearticles values(with peel); cultivar. Also, in terms of the highest fruit length and fruit height was found with peel and without peel forms of Gross Michel cultivar. In point of total soluble solid content, pH and titratable acidity values were obtained 22.1 %, 4.1 and 0.48 % for Dwarf Cavendish banana cultivar, these values were found 21.533 %, 4.6 and 0.503 % for Gross Michel banana cultivar, respectively. On the other hand, fruit firmness value was found to be 4.233 N/mm for Dwarf Cavendish cultivar and 4.500 N/mm for Gross Michel cultivar. However, no statistically significant differences were found in terms of fruit peel color among the varieties in the experiment. In addition, the antioxidant activities of the fruit pulp extracts were evaluated by using the free radical scavenging, hydrogen peroxide insert ignore into journalissuearticles values(H2O2); scavenging and metal insert ignore into journalissuearticles values(Fe+2); chelating activities methods. Dwarf Cavendish banana cultivar fruit pulp had higher anti-oxidant activity at the ripe stage than Gross Michel banana cultivar.
