RESUMO
Abstract In the postharvest stage, taste and flavor are the key components of the marketability of tomato. Therefore, greater emphasis is now being placed on improving traits such as sugar content. In this study postharvest ultraviolet-B (UV-B) treatments on sugar, total soluble solids, and color of tomatoes harvested at different stages were investigated. Tomatoes harvested at turning, pink, and red stages were treated with two different doses of UV-B irradiation: UVB4 and UVB8. Color L* and hue angle values of tomatoes treated with UV-B were found to be high, which means the red color of tomatoes was improved. UVB4 treatments increased the color a* and saturation index values of tomatoes at pink and red harvest stage, although it did not affect at the turning stage. Additionally, UV-B irradiation treatments had no effect on sucrose content of the tomatoes. Fructose, glucose, and TSS content of tomatoes treated with UVB8 at red harvest stage were found to be high. Hence, the results obtained from this study are of great importance in terms of providing an increase in the amount of sugar without the need for breeding, and also consumer satisfaction.
