Assessment of the impact of formalin treatment on the quality and shelf life of mango
This study was conducted to observe the effect of formalin application on the post-harvest quality and shelf life of mango. Mango samples were treated with different concentrations of formalin solutions (10, 100 and 1000 ppm) in two different modes (dipping and spraying) and stored for seven days at ambient condition. Physical characteristics, such as weight loss, color, texture and shrinkage and residual formalin content were observed at every alternate day during storage period. Formalin treatment (dipping and spraying) did not bring up any positive effect in increasing the shelf life of mango. Rather treated with higher concentration of formalin solution (10 ppm<100 ppm<1000 ppm) caused internal and external deterioration. Residual formalin content of mangoes for the both treatments decreased readily according to the treatment mode. The overall study indicates that the post-harvest quality and shelf life of mango could not be improved treating with any concentration of formalin either spraying or dipping mode.
