Both sweet and tart, pineapple's distinctive flavour lends a tropical touch to any dish. According to the University of California at Davis, pineapples stop ripening immediately upon removal from the tree, but you can decrease the amount of green visible on a pineapple's exterior by using ethylene gas. Fruits such as apples, nectarines and pears naturally release ethylene gas. When trapped in a paper bag with a pineapple, this gas can change the pineapple's colour from green to a yellow on the exterior, making the fruit appear to ripen, but the inside of the fruit will not change in texture or quality, according to the University of California at Davis.
