  • Method of preventing gushing of packaged beer
    Patent number: 4181742
    Abstract: Most beers brewed with the addition of cysteine proteases, such as papain, ficin or bromelain, for the purpose of chillproofing develop a tendency to gush or foam excessively after being stored in bottles and cans for 1 to 3 months. This gushing tendency is obviated by adding during the beer manufacturing process a special kind of acid protease whose proteolytic activity is specifically inhibited by the pepsin inhibitor S-PI from Streptomyces naniwaensis.
