摘要:
PROBLEM TO BE SOLVED: To provide a lactic acid bacterium fermentation product using a polyphenol component, such as a water extract of pine bark, astringent skin of peanuts, grape seeds or azuki beans, and a method for producing the same.SOLUTION: The lactic acid bacterium fermentation product is obtained by lactic acid-fermenting, for example, a water extract of azuki beans with Lactobacillus piantarum. As the water extract of azuki beans, use can be made of, for example, a broth that is obtained by cooking azuki beans in water in the course of producing a sweat azuki bean paste. The lactic acid bacterium fermentation product has an anti-SARS (Sub-Acute Respiratory Syndrome) corona virus activity thrice or more as high as the activity of the unfermented material. This lactic acid bacterium fermentation product is widely usable as a starting material to be added to drinks, foods such as ice creams, baked products, candies, chewing gums and desserts, tablets, injections, nasal drop compositions for preventive and therapeutic uses, drops, gargle solutions and mouth washers.
