3. The fruit is transported to the packaging section, and fruits that meet the characteristics required for export to Japan are selected. Every fruit is manually cleaned to avoid the damage and pollution of the machines.


4. The fruit is dipped in hot water for 75 to 110 minutes, depending on the weight of the mango. Temperatures are monitored and recorded by a certified inspector system.
