PROCESS FOR PRODUCING HOP GLUME POLYPHENOL

摘要

It is intended to provide a process for efficiently producing highly purified hop glume polyphenol using hop glume as the starting material, and foods, drinks, cosmetics and drugs with the use of the highly purified hop glume polyphenol. Namely, a process for producing hop polyphenol which comprises extracting hop glume with an aqueous alcohol solution, concentrating the extract to give a residual alcohol concentration of 0.5 to 2% and then centrifuging and/or filtering the concentrate. This polyphenol is usable in foods, drinks, cosmetics, drugs, etc.
