Once it’s cracked, it will start going bad. Therefore, the best place to keep them when it’s hot is where it’s cool like in the pantry.

Longan can be stored as a whole fruit or they can be peeled and stored just the flesh in the fridge. If you storing the whole fruit, you can pick the stem and leaves off each fruit before storing it. Make sure to not rip the stem out from the fruit as it could cause a tear in the skin. Instead, gently pull back the stem on each fruit.

If storing just the flesh, peel the skin off the fruit and put them into an airtight container. You can either store the fruit with the seed or with the seed removed. Leaving the seed intact will help maintain their texture and prevent the fruit from breaking apart.

For canned longan, it’s the same as for any other canned food. It should be stored in a cool, dry place, and away from direct sunlight. A good location for storing canned longan will be the pantry, cupboard, or even the fridge. Just make sure to keep them where they won’t get damaged easily by other food products.
