It is intended to provide a composition against periodontal bacteria, which has a high safety without showing any side effects and exhibits an excellent effect of killing periodontal bacteria without affecting the growth of nonpathogenic indigenous microorganisms in the oral cavity, and foods, drinks and mouth washers against periodontal bacteria. A composition against periodontal bacteria is blended with a cocoa fraction contained in cacao mass, a hot water-extract of the cocoa fraction, polyphenols originating in the cocoa fraction or free fatty acids originating in the cocoa fraction as the active ingredient. Then the obtained composition against periodontal bacteria is added to foods, drinks or mouth washers against periodontal bacteria. It is preferable that the above-described cocoa fraction is cocoa and/or cacao mass. It is preferable that the above-described free fatty acids contain at least one member selected from among palmitic acid, stearic acid, oleic acid and linoleic acid. |
