ELIMINATING THE GENERATION OF MBT IN A HOPS BASED BEVERAGE

摘要

A method of preventing the generation of more than a tasteable concentration of MBT in a hops-based beverage having a concentration between 10 μg/l and 10 mg/l of Riboflavin includes holding the beverage in a container that is at least partially transparent or translucent to visible light and that has an optical filter characteristic reducing transmission to the beverage therein of all wavelengths of light between 200 nm and 510 nm, wherein the transmission reduction is sufficient to prevent the generation of a concentration of more than 35 ng/l of MBT in the beverage through photochemical reactions and photochemically initiated auto-catalytic reactions involving the Riboflavin. The container includes a wall defining an inner surface and an outer surface, and the transmission reduction is achieved by providing a film or coating having the optical filter characteristic on either the inner surface or the outer surface of the wall.
