PepsiCo has snapped up self-styled super-premium juice producer Naked Juice Co. from US private equity group North Castle Partners.

The US soft drinks giant said the deal, secured for an undisclosed sum, was another step in its aim to further meet US demand for "health and wellness" products.

Based in California and formed in 1983, Naked Juice has a portfolio of 25 juice and smoothies made without any added sugars or preservatives. The Naked Juice stable is divided into functional families, each providing a different group of benefits. The families include superfoods, antioxidants and proteins.

PepsiCo said it would broaden the distribution of the products, while continuing to use Naked Juice's "successful grassroots marketing and sales efforts". Naked Juice already enjoys annual turnover of around US$150m.

Greg Shearson, president of Tropicana Products North America, a unit of PepsiCo, said: "Naked Juice's consumers and customers are passionate about this brand. We value that level of loyalty and look forward to building on it to help Naked Juice continue to grow."

Naked Juice CEO Monty Sharma said he was excited at the prospect of joining PepsiCo. He added: "Becoming part of PepsiCo will allow us to expand our distribution and continue to demonstrate our commitment to bring the best all-natural juice and juice smoothies to more consumers."
