Less salt, more protein: Addressing dairy processing's environmental, sustainability issues

Researchers say the high salt content of whey—the watery part of milk left behind after cheesemaking—helps make it one of the most polluting byproducts in the food processing industry. In a new study, chemists demonstrate the first electrochemical redox desalination process used in the food industry, removing and recycling up to 99% of excess salt from whey while simultaneously refining more than 98% of whey's valuable protein content.
