Wrigley's Juicy Fruit Gum
Wrigleys' chewing gum began as a free gift given to customers who purchased the company's baking powder, but the gum proved the more popular item. The Juicy Fruit flavor debuted at the 1893 Columbian Exposition and even more people got hooked. Some think the sweet, vaguely fruity flavor comes from isoamyl acetate, while others believe it could be derived from jackfruit.
