Separating beer waste into proteins for foods, and fiber for biofuels

ACS Virtual PRESS SESSION 03 Tuesday, April. 6th at 10 a.m. EDT Home brewing enthusiasts and major manufacturers alike experience the same result of the beer-making process: mounds of leftover grain. Once all the flavor has been extracted from barley and other grains, what’s left is a protein- and fiber-rich powder that is typically used in cattle feed or put in landfills. Today, scientists report a new way to extract the protein and fiber from brewer’s spent grain and use it to create new types of protein sources, biofuels and more.
