Mangoes may lose weight during transit due to several factors. Here are some common reasons:

Moisture loss: Mangoes have a high water content, and during transit, they can lose moisture through evaporation. This can occur due to exposure to dry and warm conditions, prolonged transportation times, or inadequate packaging that doesn’t provide sufficient moisture retention. As moisture evaporates from the fruit, its weight decreases.

Respiration and metabolic processes: Mangoes are living organisms and continue to undergo respiration and metabolic processes even after being harvested. These processes consume energy and result in the breakdown of carbohydrates, which can lead to the release of water and carbon dioxide. The loss of water through respiration contributes to the weight reduction of mangoes.

Ripening: Mangoes continue to ripen during transit, especially if they were harvested at a slightly unripe stage. Ripening involves various biochemical changes, including the conversion of starches to sugars and the breakdown of cell walls. These processes can result in the loss of water and a decrease in fruit weight.

Ethylene exposure: Mangoes are sensitive to the plant hormone ethylene, which is naturally produced by fruits as they ripen. If mangoes are transported in the presence of other ethylene-producing fruits or in an environment with high ethylene concentrations, it can accelerate their ripening process and increase moisture loss, leading to weight reduction.

Handling and mechanical damage: Rough handling or improper stacking during transportation can cause physical damage to the mangoes, such as bruising or punctures. This damage can accelerate moisture loss and contribute to weight loss.

It’s important to note that some weight loss during transit is expected and considered normal. However, excessive weight loss can be detrimental to the quality and market value of mangoes. Proper post-harvest handling, including appropriate packaging, temperature control, and monitoring of humidity levels, can help minimize weight loss and maintain the overall quality of mangoes during transit.
