Abstract
Abstract A beverage is made by removing pectic substances and tannin from fruit juice or fruit extract by addition of an acidified solution of protein having a pH not exceeding 3.7. The pectic substances and tannin interact with the acidified solution of protein and are removed as coagulum. If desired, the fruit juice or extract may be pretreated with pectinase. The resultant fruit juice or fruit extract may be mixed with an acidified solution of protein such as acidified skim milk without further formation of coagulums so that a stable beverage is obtained.
