  • Absorptive treatments for improved beer flavor stability
    Patent number: 6207208
    Abstract: A process for reducing the propensity of riboflavin-containing malt beverages employs the treatment of beer or its intermediates with Fuller's earth absorbents and, in particular, colloidal magnesium aluminum silicates, especially attapulgite and montmorillonite clays. This process effects absorbance of riboflavin contained in such beer or its intermediates and can be shown to improve the stability of a treated beer against the formation of skunky off-flavors following exposure to visible wavelengths of light.
