Abstract: The postharvest quality of tomato fruit harvested at the pink stage and dipped in 3 different concentrations of CaCl2 for different dip times (30, 20 and 10 minutes) were studied. Tomato fruits dipped in 6% CaCl2 for 30 and 20 minutes retained significantly (P < 0.05) higher level of firmness, titrable acidity and vitamin C than fruits dipped in 2% CaCl2 and the control. The calcium chloride treated fruits showed significant (P < 0.05) levels of delay in the changes of weight loss, firmness, titrable acidity, total soluble solids, vitamin C and decay than fruits without CaCl2 treatment. Tomato fruits dipped in 6% CaCl2 for 20 or 30 minutes maintained significantly (P < 0.05) higher vitamin C and firmness than fruits dipped for 10 minutes and the control. Therefore, postharvest quality of tomato fruits such as vitamin C, titrable acidity, weight and firmness can be maintained by harvesting at the pink stage and dipping in 6% CaCl2 for 20 minutes. Maintaining these postharvest parameters may help enhance the profitability of farmers and marketers of tomato fruits and as well improve the livelihood and food security of Ghanaian communities.
