Pineapple

The Pineapple may be all green or variously striped with red, yellow or ivory down the middle or near the margins.

the Pineapple is both juicy and fleshy with the stem serving as the fibrous core. The tough, waxy rind may be dark green, yellow, orange-yellow or reddish when the fruit is ripe. The flesh ranges from nearly white to yellow

The fruit shell will gradually turn yellow beginning at the base of the fruit. Over time the fruit will become completely yellow if left standing on the kitchen counter for a few days. The same color change occurs if the fruit is left on the plant in the field. The flavor will also change slightly but there will be no increase in sugars as occurs with fruit allowed to ripen on the plant. Some fruits such as bananas, peaches and pears do ripen when kept at room temperature for a few days because they contain starch that is converted to sugar during the ripening process.
