Yes, wrapping unripe mangoes in newspaper can help them ripen faster. The newspaper traps ethylene gas, a natural ripening agent produced by the fruit.
Mangoes, like many fruits, produce ethylene gas as they ripen. This gas triggers a series of biochemical changes within the fruit, leading to softening, color change, and the development of characteristic flavors and aromas. Wrapping unripe mangoes in newspaper creates a confined space, increasing the concentration of ethylene gas around the fruit. This elevated ethylene level accelerates the ripening process. The newspaper also provides a slightly warmer environment, further aiding in ripening. To ripen mangoes using this method:
Select unripe mangoes that are firm to the touch.
Wrap each mango individually in a sheet of newspaper.
Place the wrapped mangoes in a cardboard box or paper bag.
Store the box or bag at room temperature (ideally between 20°C to 25°C or 68°F to 77°F).
Check the mangoes daily for ripeness. They are ready when they yield slightly to gentle pressure and have a fragrant aroma.
Avoid using plastic bags, as they can trap moisture and lead to mold growth. Newspaper allows for some air circulation while still concentrating the ethylene gas.
