Is carbonated milk the next cool drink in town? A company is coming out with a new drink called e-Moo, which is a milk-based carbonated beverage. However, the product can't be marketed as milk, even though it's just the addition of carbon dioxide to pasteurized milk, but must be sold as a beverage. This is because the USDA has strict definitions of what can be sold as a milk product, and carbon dioxide is not one of the allowed additives to milk. The carbonation does the same thing in soft drinks as in e-Moo. It provides the burst of taste that comes with the bubbles. Also, it extends the shelf life of what you would expect from milk. With refrigeration, the company says that e-Moo can last six weeks.
