Abstract:

Effects of different temperatures and ozone treatments on quality of tomato fruits during storage were investigated in the present study. Results indicated that total soluble solids, titratable acids and vitamin C contents in tomato fruits could be effectively maintained during storage at (12.0 ± 1.0) ℃ combined with 200 mg/m3 ozone treatment for 0.5 h at a 3-day interval. Moreover, increase rate of relative conductivity for tomato fruits was attenuated, and respiration intensity and decay rate of tomato fruits were significantly reduced. Furthermore, the firmness of tomato fruits was also effectively maintained. Therefore, the optimal ozone treatments combined with appropriate temperature provided an excellent fresh-keeping effect on tomato fruits during storage.

Key words: tomato, appropriate temperature, ozone treatment, storage quality
