Coke and Pepsi have announced details of their respective assaults on the health-conscious orange juice market.

Coke yesterday unveiled its launch of Minute Maid Premium Light, which is now shipping to grocery stores and mass merchandisers nationwide.

The drink contains 50 calories and 10 grams of sugar per 8-fluid-ounce serving, compared to the 110 calories and 24 grams of sugar in an equivalent serving of regular orange juice.

In addition, Minute Maid Premium Light also offers nutrients needed for a balanced diet, including 120% of the Daily Value (DV) for vitamin C, and as much calcium (35% DV) and vitamin D (25% DV) as a glass of milk in every 8-fluid-ounce serving. It also contains 13% of the DV for potassium and 10% of the DV for thiamin.

"The Coca-Cola Company has always been committed to meeting the changing needs of consumers, and Minute Maid Premium Light orange juice beverage provides an alternative to juice drinkers looking to stay fit and healthy without having to forgo taste," said Donna Shields, R.D., senior manager of heath and nutrition strategic communications at Coke. "At the Coca-Cola Company, nutrition innovation is driven by the health needs of our consumers."

The beverage will be available in 64-ounce cartons and six-count 8-fluid-ounce multipacks in chilled sections of grocery stores and mass merchandisers. It is comparably priced with other Minute Maid Premium 64-ounce and multipack orange juice products. Minute Maid Premium Light 64-ounce cartons are currently shipping nationwide and multipacks will be available in select retailers.

Also yesterday, PepsiCo. said that it was rolling out a revised version of its Tropicana Light 'n Healthy orange juice product, which debuted in 64-ounce cartons in the United States earlier this year.

The beverage will contain 55 calories and 11 grams of sugar per 8-fluid-ounce serving, about 20% less than the drink that hit stores in January. The entire roll-out is expected to be completed over the next two months.
