Pineapples are a delicious tropical fruit, packed full of vitamins, minerals, fiber and enzymes that promote good digestion and help to maintain ideal weight and balanced nutrition. The pineapple is also high in the enzyme bromelain and the antioxidant vitamin C, both of which help the body to heal. This amazing fruit comes packaged in a protective outer skin which sometimes makes it difficult to determine spoilage. Knowing when to throw away a pineapple that has reached expiration will help avoid an unpleasant surprise at first bite.


Taste

A spoiled pineapple will begin to take on a bitter or “spicy” taste, as opposed to the sweet and tangy taste of the ripe variety. At this stage, a pineapple should be thrown out.

Color of Flesh

The flesh of a spoiled pineapple will change from its healthy yellow color to a more pale white. At this stage, a pineapple should be thrown out.

Smell

A spoiled pineapple will begin to smell of alcohol as part of the fermentation process. At this stage, a pineapple should be thrown out. A ripe pineapple should have a sweet, fruity smell.

Texture

The outer walls of a spoiled uncut pineapple will begin accumulate soft brown spots that leave an indentation when pressed in with little force. Beyond expiration, the inner flesh of the pineapple will also take on a soggy texture. At this stage, a pineapple should be thrown out. A ripe pineapple should have both a firm outer and inner texture.

Outer Appearance

A spoiled pineapple will often display white foam on it, typically on the base. At this stage, a pineapple should be thrown out. A ripe pineapple will have supple green leaves at the top and not display any foamy, white secretions.
