How to Tell if Dried Mango is Bad?
Dried mango will keep its finest quality for around 12 to 18 months if stored properly, although it will be safe for longer. How do you tell whether a dried mango is rotten? The best technique is to smell and inspect the dried mango: discard any that have an off-odor or appearance, and discard any that have mold.
If your dried fruit has a foul odor, it has probably gone bad.
