  • Enzymatic clarification of liquids
    Patent number: 4038419
    Abstract: An enzyme protease derived from induced fermentation of Streptomyces fradiae is used to clarify the actual or potential turbidity of an aqueous liquid such as a beverage by adding the enzyme to the liquid in an amount such that the enzyme activity is 200,000 to 20,000,000 UA per Hl. of the liquid. Some advantages of using this protease enzyme are that it is autodestroying and is not present in a beverage after storage, that it has low toxicity and that it can be sterilized by dry heat without significant loss in activity.
