ABSTRACT: Research suggests that a key determinant of instability in beer is peroxide. Any mechanism that reduces peroxide levels in beer, thereby preventing their direct damaging effect or their ability to convert to even more damaging species (notably hydroxyl), would be predicted to enhance the shelf life of beer. We have investigated potential enzymic solutions for affording such protection.
