The recommended storage temperature to extend the shelf life of banana is:

• Bananas are tropical fruits sensitive to cold temperatures. Storing them at 12-15 °C helps to:
-Slow down ripening: This temperature range slows down the metabolic processes in bananas, delaying the ripening process and extending their shelf life
-Prevent chilling injury: Temperatures below 12 °C can cause chilling injury to bananas, leading to discoloration, softening, and off-flavors
