Chilling Injury
Chilling injury is damage caused by temperatures that are too low for a sensitive plant tissue even when the tissue does not freeze. In mango fruit it can lead to poor or uneven ripening, surface discoloration, pitting, and reduced flavor, depending on maturity and exposure. It is different from frost damage to a living tree. Commercial storage temperatures must suit the fruit's condition; at home, allow mature unripe fruit to ripen appropriately before using refrigeration to slow deterioration of ripe fruit.
