intain the ideal environmental conditions required by the produce throughout the journey. 2.3 Humidity and Water Loss Fruits and vegetables lose water after harvest through transpiration. In the absence of water supply from the mother plant they may wilt, shrivel, become tough, and lack avor (Nicholas, . Excessive water loss directly affects the appearance and marketable weight of the produce. Transpiration is function of the produces moisture content and the ambient relative humidity. Most fruits and vegetables contain around 8% to 9% water by weight (Nicho-las, . Unless the relative humidity of the surrounding air is close to 1%, produce 5 Hui et al. continues to lose water to its environment. The transpiration rate is also affected by certain properties of the fruits and vegetables (.., morphological and anatomical characteristics,surface-to-volume ratio, surface injuries, and maturity stage) and other environmental con-ditions (.., temperature, air movement, and atmospheric pressure) (Kader, . During transport, produce water loss can be reduced by 1. Maintaining high relative humidity around the produce - Maintain small temperature gradient between the evaporator coils and thecirculating air (if large temperature gradient exists, water vapor in the aircondenses on the coils and the air is dry).- Install humidity control system. - Top-ice produce that is water-resistant or add ice within the produce packag- ing. - Cover the produce or its container with semipermeable wrap. 2. Reducing the water permeability of produces surface - Apply wax to the surface of the produce. 3. Reducing the ambient air movement - Provide only enough air movement to remove the heat of respiration. 4. Reducing the produces moisture loss through respiration - Precool the produce thoroughly, prior to shipping, to reduce the temperaturedifferential between the produce and the surrounding air. 5. Reducing the water holding capacity of the surrounding air - Maintain low temperatur
