As the hangover relieving drink market has been expanded, there have been efforts to produce traditional drinks that can be easily taken through reducing material costs after finding materials with high alcohol-degrading activity from agricultural products and manufacturing drinks in a way to produce sikhye. Studies were made to know quality, the ability to relieve hangover and preference of drinks for which seven kinds of agricultural products, including shiitake mushrooms, were added in the forms of fresh juice, extracts and powder. Farm products showed the highest acetaldehyde dehydrogenase (ALDH) when they were added in the form of powder before saccharification and shiitake mushrooms showed the highest enzyme activity when they were added in the form of powder. When added in the form of powder, people showed the lowest preference except when radish and hericium erinaceum were added. When bear puree was added to a mixture of powdered shiitake mushrooms, radish, bean sprouts and dadagi cucumber, enzyme activity got higher and people showed higher preference. An experiment of animal behaviors showed that the mixture had a high ability to relieve hangover in one or two hours after 10% or 40% alcohol was orally administered to mice due to long traveling distance of mice.
