Bioactive Compounds of the PVPP Brewery Waste Stream and their Pharmacological Effects

Beer, one of the most commonly consumed alcoholic beverages, is rich in polyphenols and is the main dietary source of xanthohumol and related prenylflavonoids. However, to avoid haze formation caused by the interaction between polyphenols and proteins, most phenolic compounds are removed from beer and lost in the brewery waste stream via polyvinylpolypyrrolidone (PVPP) adsorption. This waste stream contains several polyphenols with high...
