Whey's Growing Role in Feeding a Hungry World: Advancing technology brings big business to protein industry

MILWAUKEE - Got whey? From infant formula and protein supplements to sports drinks and nutrition bars, whey - the nursery rhyme food that was once a ditch-dumped byproduct of cheese making - is taking on growing clout as a global food ingredient. And food scientists are seeking even more uses for the protein-dense product that can help build muscle and lean bodies.The Wisconsin Center for Dairy Research at the University of Wisconsin-Madison last week picked up a $1 million grant from the U.S. Department of Commerce to develop higher-value whey products for export, including new products for fast-growing Asian markets. Researchers also will be working to develop healthier dairy-based alternatives for school lunches in the United States.
