Abstract

Tomatoes (Lycopersicon esculentum) are popular for consumption all over the world, but due to the fact that after harvesting, tomatoes change their internal composition leading to their deterioration, resulting in short shelf life. Therefore, the objective is to study the effect of UV-C irradiation on the quality of Cherry tomatoes. UV-C irradiation at 2 kJ m-2 and storage at 5° C for 28 days. After 28 days of storage, UV-C had a weight loss of 0.49%, which is more than control treatments (0.37%). UV-C irradiation was able to slow down the reduction of the firmness value of 5.3 N, which is greater than the control treatment (4.7 N). UV-C irradiation was able to delay the reduction of the firmness equal to 5.3 N, which is greater than the control treatment (4.7 N), stimulate the accumulation of vitamin C, the values were 33.2 and 31.6 mg / 100 g ml in UV-C treatment and control, respectively, stimulates the accumulation of antioxidant content (1.18-1.2 AAE / g FW), and stimulate the accumulation of flavonoid compounds 14.1 and 12.1 mg / 100 g FW in UV-C treatment and control, respectively. Including stimulating lycopene accumulation in cherry tomatoes was 5.16 while control treatment was 4.89 mg / 100 g FW of lycopene. UV-C irradiation is effective in maintaining the quality and extending the shelf life of cherry tomatoes.
