【摘要】 超氧化物歧化酶(SOD)是一种广泛存在于生物体内的金属酶,通过催化超氧阴离子自由基(O2-)发生歧化反应,将其转变为过氧化氢和氧气,清除机体代谢过程中产生的过多的自由基,减轻或消除超氧阴离子自由基(O2-)对机体的损害。SOD在防辐射、抗衰老、防治肿瘤等方面具有独特的功能,也是一种重要的功能性食品原料。近几年SOD在食品工业生产中起着重要的角色,特别是在功能性食品加工中。本文主要对SOD的基本理化性质、抗氧化作用、在食品工业中各领域的应用现状及存在的问题进行了概述。更多还原

【Abstract】 Superoxide Dismutase(SOD)is one of metal enzymes widely existed in organisms.SOD catalyzes the dismutation reaction of O2-in order to eliminate the effect of O2-,which is transformed into hydrogen peroxide and oxygen.SOD has a particular effect on resisting to radiation,aging and antitumor.It plays an important role on food industry,especially on functional food.In this paper,the SOD’s physicochemical properties,antioxidation and the application in food industry are reviewed.更多还原
