PROBLEM TO BE SOLVED: To provide methods for processing shell ginger (Alpinia zerumbet) components based on the findings that fermentation of shell ginger components contributes to treatment or prevention of periodontal disease, and that anti-oxidant activity and beautiful skin effect are improved by choosing the position of shell ginger to be fermented or by varying the treatment process.SOLUTION: Provided is a method for treating the periodontal pathogen characterized in that the components of shell ginger are fermented after the components are sterilized by using heat or germicide, so that the fermentation product can kill periodontal pathogen but not skin-indigenous bacteria such as Staphylococcus epidermidis and Propionibacterium acnes. Also provided is a method for producing a skin-beauty material characterized in that fermentation is carried out after intact shell ginger or its juice or extract is sterilized by heat or germicide treatment, or the residue of heat concentration is fermented to enhance the tyrosinase-inhibiting activity or hyaluronidase-inhibiting activity. Further provided is a method for enhancing the antioxidant activity of the shell ginger-derived components characterized in that the residue of heat concentration of shell ginger components is fermented.COPYRIGHT: (C)2014,JPO&INPIT【課題】歯周病の治療や予防に貢献すると共に、発酵させる月桃の部位や処理法によって抗酸化力や美肌効果を改善できることを発見した。【解決手段】歯周病菌を死滅させ、皮膚常在菌であるアクネ菌や表皮ブドウ球菌の死滅又は殺菌力を抑制するために、月桃成分を加熱や殺菌剤による殺菌後に発酵させることを特徴とする歯周病菌の対処方法である。また、月桃又は月桃の搾汁若しくは抽出液を加熱や殺菌剤により殺菌してから発酵させるか、又は加熱濃縮後の残留物を発酵させることによって、チロシナーゼ阻害活性又はヒアルロニダーゼ阻害活性を高めることを特徴とする美肌物質の製造方法である。さらに、月桃成分の加熱濃縮後の残留物を発酵させることを特徴とする月桃由来成分の抗酸化作用の増強方法である。【選択図】図1
