Antioxidant, tyrosinase activity inhibitor and whitening agent containing the antioxidant, and method for producing the antioxidant and the whitening agent
It is an object to provide excellent antioxidants and whitening agents, and to provide a new agent containing "components contained in Phalaenopsis orchid" which is solid-liquid separated by a specific method. The above-mentioned problems were solved by an antioxidant, a tyrosinase activity inhibitor, and a whitening agent, which contain an extract of Phalaenopsis of the family Orchidaceae) or an extract residue of Phalaenopsis orchid as an active ingredient. The Phalaenopsis orchid is preferably leaves of the Phalaenopsis orchid, and the method for producing the antioxidant is as follows. The Phalaenopsis orchid is crushed and stirred with a stirring blade without adding an extraction solvent, and the crushing and stirring is performed from the outside. The method is characterized by comprising a step of obtaining an extraction liquid or an extraction residue by solid-liquid separation by reducing pressure while applying heat while maintaining a temperature range of 25 ° C. or higher and 45 ° C. or lower. [Selection diagram] Fig. 4優れた抗酸化剤や美白剤を提供することを課題とし、また特定の方法で固液分離した「胡蝶蘭に含まれる成分」を含有する新たな剤を提供することを課題とし、胡蝶蘭（ラン科ファレノプシス属）の抽出液又は胡蝶蘭の抽出残渣を有効成分として含有することを特徴とする抗酸化剤、チロシナーゼ活性阻害剤、及び、美白剤によって上記課題を解決した。該胡蝶蘭は胡蝶蘭の葉であることが好ましく、該抗酸化剤の製造方法は、抽出溶媒を加えずに、胡蝶蘭を撹拌羽根で破砕しながら撹拌し、該破砕・撹拌下に外部から２５℃以上４５℃以下の温度範囲に維持しながら熱を加えつつ減圧し、固液分離することによって抽出液又は抽出残渣を得る工程を有することを特徴とする。【選択図】図４
