Can you use pineapple juice if it is past the expiration date on can?

No, you should not use pineapple juice if it is past the expiration date.

Expiration dates are put on food products for a reason. They indicate the date after which the product may not be safe to consume. This is because food products can spoil over time, and consuming spoiled food can make you sick.

While pineapple juice may not be immediately dangerous after its expiration date, it's best to err on the side of caution and discard it. There's no way to know for sure whether it's still safe to drink, and it's not worth the risk of getting sick.
