Cherry tomato is rich in Vitamin C. It is on demand and can be eaten straight away.<br />

However, improper postharvest handling affected their quality and shelf life. This<br />

study identified the effect of hot water and calcium chloride dipping on postharvest<br />

quality of cherry tomato. The fruits were treated at 45°C, 55°C with and without CaCl2<br />

dipping. Meanwhile for control A, the fruits were dipped with only 1% CaCl2 and control<br />

B is without any treatment. Tomato treated at 55°C with 1% CaCl2 dipping has a<br />

potential in control the weight loss and could maintain the firmness of cherry tomato.<br />

CaCl2 help in reducing respiration, physiological disorders and can delay softening of<br />

fruits. This study provided information regarding the potential postharvest treatment<br />

of cherry tomato and further study can be conducted by manipulates the time length<br />

for hot water treatment and dipping processes.<br />
