Ergothioneine is a kind of precious amino acid, and it is also a natural antioxidant. It plays an important role to prevent the oxidative damage in organism. Ergothioneine cannot be biosynthesized in humans, only can be absorbed from the diet. In recently the research discovered the high content of ergothioneine in the mushroom. Content of ergothioneine of Pleurotus eryngii is the highest from 28 kinds of mushrooms, therefore the research untilized P. eryngii to make the products of P. eryngii-fermented adlay and P. eryngii-fermented buckwheat which content high ergothioneine. Also, we analyzed their proximate composition, nutritional components, taste and physiologically active components, antioxidant properties and evaluation of anti-imflammatory effect.

中文摘要麦角硫因为一种稀有的胺基酸，也是天然的抗氧化剂，其在生物体内对氧化压力伤害之预防扮演著重要角色，麦角硫因不能在动物体内合成，仅能由食物中摄取，近年来发现在菇类中含有高含量的麦角硫因，从28种食药用菇类中筛选出麦角硫因含量较高的菌种，以杏鲍菇子实体最高(1521.6 mg/g dw)，因此本论文以杏鲍菇为媒介，利用固态发酵方式，制备出高麦角硫因之杏鲍菇薏仁和杏鲍菇荞麦，并针对薏仁、杏鲍菇薏仁、荞麦、杏鲍菇荞麦和杏鲍菇菌丝体，进行一般成分、营养、物性、呈味、生理活性物质、抗氧化性质之分析及抗发炎反应之评估。
