WhiteWave Foods, the organic unit of Dean Foods, has entered into a partnership with Martek Biosciences to develop products to be launched in 2007 containing DHA (docosahexaenoic acid) omega-3.

The deal extends an existing cooperation agreement, and will see WhiteWave launch an organic milk containing DHA under the company's Horizon Organic brand. WhiteWaves will also launch yoghurt fortified with DHA under the Rachel's brand.

Joseph Scalzo, president and CEO of WhiteWave said: "DHA is an ingredient that has been shown to provide important health benefits in young children and across the lifecycle. Horizon Organic is the leading organic dairy brand with a proud history of pioneering in healthy, organic products and we look forward to the impact of this ingredient in enhancing our product offerings and once again pioneering our business into new arenas."

DHA omega-3 is a long-chain fatty acid supports brain, eye and cardiovascular health.
