PROBLEM TO BE SOLVED: To provide a method for obtaining an effective component of mushroom such as hiratake mushrooms, shiitake mushrooms, or tamogidake mushrooms in a short time with high yield.SOLUTION: With media for mushrooms, adsorbents such as activated carbon and ion exchange resin are directly mixed, so that effective components are adsorbed and processed. Effective components, that is bioactive components such as &beta-glucan and ergothioneine are thus efficiently extracted from mushrooms.COPYRIGHT: (C)2012,JPO&INPIT【課題】ひらたけ、しいたけ、たもぎだけなどのきのこ類の有効成分を短時間で高収率で得られる方法を提供する。【解決手段】きのこ類の培地に活性炭、イオン交換樹脂などの吸着材を直接混和して有効成分を吸着、処理する、きのこ類から効率的に有効成分すなわち、生理活性成分のβ-グルカン、エルゴチオネインなどを抽出する。【選択図】なし
