Pineapple may be a tropical fruit, but don't think it can resist spoiling without proper refrigeration, particularly after it has been cut. While refrigerated pineapple is expected to last for a few days when properly stored in the refrigerator, you should rely on your senses to determine if pineapple is still good to eat by closely examining its appearance, scent and taste before serving or consuming.
A pineapple's shelf life is dependent upon when it was picked. Pineapples do not continue to ripen once harvested, so select the freshest-looking fruit to ensure a longer shelf life. When purchasing whole pineapple, look for one that is golden brown in appearance, feels heavy for its size and gives off a pleasantly sweet scent. Alternatively, pass on pineapples that are bruised, have a soft, soggy bottom, have withered, brown leaves or appear dry.
To Refrigerat or Not To Refrigerate: Whole Pineapple
Whole, uncut pineapple is best stored at room temperature, where it will last for 2 to 3 days. Before using pineapple that has been sitting out for 3 days, examine it carefully for signs of spoilage. If the bottom of the pineapple has become soft and soggy or it's giving off a pungent sour smell or a scent like alcohol, it should be discarded. Whole pineapple that has been sitting at room temperature for 3 days (that shows no signs of spoilage) can be stored in the refrigerator to increase the shelf life by 1 to 2 days. Wrap the pineapple tightly in a plastic bag and store it in the crisper section of your refrigerator..
Cooling the Cut Pineapple
Cut pineapple should be stored in a tightly sealed container in the refrigerator where it will last for 3 to 4 days. If you purchased pre-cut pineapple, abide by the prepared date to determine its shelf life. If the flesh of the fruit has turned a darker gold color, is giving off a chemical smell, or has an off-taste that is sour and vinegary, it should be discarded.
Cut pineapple can be safely stored in the freezer for 3 to 5 months. Store it in a tightly sealed, freezer-safe container or storage bag and label the container with the date to keep track of when it should be used.
