PREVENTING THE GENERATION OF 3-METHYLBUT-2-ENE-1-THIOL (MBT) IN A HOPS BASED BEVERAGE

摘要

A bottle, container or beverage glass for containing a hops based beverage, in particular beer, includes a concentration between 10 μg/l and 10 mg/l of Riboflavin. The bottle, container or beverage glass are at least partially transparent or translucent to visible light and have an optical filter characteristic preventing light transmission at the wavelength intervals 220-230 nm, 250-270 nm, 350-370 nm and 440-450 nm to a level preventing generation of more than a tasteable concentration of MBT in the beverage through photochemical reactions and photochemically initiated auto-catalytic reactions involving the Riboflavin. The tasteable concentration is between 1 and 35 ng/l, preferably between 5 and 25 ng/l, and more preferably 10 ng/l.
