Ripening a Pineapple at Home
Do you sometimes buy an under-ripe pineapple anticipating that it will ripen at home? Don't bet on it.
Duane Bartholomew, dean of the University of Hawaii agronomy and soil science department, says a pineapple is ready to eat when harvested. The flavor of one that is harvested too early will change only slightly if left to ripen at home.
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. But not pineapple.
As the pineapple sits on your kitchen counter, its shell will gradually turn yellow beginning at the base of the fruit. If left standing for a few days, the fruit will become completely yellow. But there will be no increase in sugars as would occur if the fruit had been allowed to ripen in the field.
