The ingredients in Extra gum vary depending on the flavor, but they generally include a gum base, softeners, bulking agents, flavoring, coloring, preservatives and sweeteners. All ingredients used in Extra gum undergo intense testing to ensure their quality.
The gum base in Extra gum is composed of synthetic material that makes the gum chewy and binds it together to create a smooth texture. Softeners and bulking agents, which usually include glycerin and vegetable oil products, keep the gum soft and flexible. Extra gum contains both natural and artificial flavors. Flavoring may be derived from mint plants grown in the United States or various fruit and spice essences. Coloring, such as Blue 1 Lake, Red 40 and Yellow 6, is utilized to differentiate between flavors visually.
Extra gum does not contain sugar, so it is sweetened with artificial sweeteners, including aspartame, maltitol, sucralose, sorbitol and xylitol. These sweeteners do not cause tooth decay and provide long-lasting taste that is free of calories. BHA and BHT are the main preservatives used to keep the gum fresh. As of 2015, Extra gum is available in a wide variety of flavors, including Spearmint, Sweet Watermelon, Winterfresh, Polar Ice and Mixed Berry. Extra also features Dessert Delights flavors, including Cinnamon Roll, Mint Chocolate and Peach Cobbler.
