Useful Whey

To James Louis Kraft, cheese tycoon, went news both profitable and philanthropic last week. His Kraft-Phenix Cheese Corp. used to dump away yearly thousands of gallons of whey (the watery part of milk left after the curds are removed) or return it to farmers for hog wash. That whey contains most of the milk minerals. To make money from this whey Mr. Kraft some time ago gave Rutgers University funds for research. Rutgers fellows developed a powdered whey which chicken farmers use to keep parasites from their fowls. A year ago Kraft developed Velveeta, a mixture of cheese and whey powder, which can be digested in two hours, while cheese requires four hours for digestion. Whey must have some further commercial value, decided Mr. Kraft. So he asked Rutgers to go deeper into its nutritional values. Dr. Lloyd Kendrick Riggs, Ph. D., 42, directed this research.

The research indicates that whey is good for both rickets and tuberculosis. The minerals it contains are those needed for building bones and for the repair of tuberculosis lesions. For those conditions whole milk is always prescribed. But the bulk of milk required often annoys the patients. Dr. Riggs, who has experimented only on animals and not yet on humans, finds that a small amount of powdered whey plus food containing the antirachitic vitamin D (evaporated from the watery cheese waste) is as curative as a quart or more of whole milk. For an account of what happened to Mr. Kraft's cheese business last week, see p. 47.
