...New formula may come to the rescue.

A new process that changes cow's milk to mimic human milk has been developed by chemist John H. Woychik at the Agriculture Department's Eastern Regional Research Center in Philadelphia.

Proteins in cow's milk differ in amount and kind from those in human milk, making cow's milk less nutritious for human babies and harder to digest. As many as 10 percent of all U.S. infants may have adverse reactions to cow's milk at some time, although less than 0.1 percent of the population has either severe or persistent allergies, a previous study has shown.

The protein chiefly responsible for such problems, beta-lactoglobulin, can now be removed cheaply in Woychik's continuous, 16-hour process, which uses a synthetic molecular membrane to filter proteins. This process also concentrates beta-casein, a beneficial protein found in both cow's milk and human milk, thus producing an excellent protein base for infants.
