摘要
目前乳酸菌的抗氧化功效已经得到体内及体外实验的证实,其抗氧化作用模式主要包括清除自由基、螯合金属离子、具有还原能力、抑制脂质氧化和提高抗氧化酶活性等。但乳酸菌起抗氧化作用的物质成分、抗氧化作用的分子机制都有待阐明。利用抗氧化活性乳酸菌开发保健品、药物和抗衰老产品将成为此领域的研究热点。本文概述具有抗氧化活性乳酸菌的国内外发展现状和研究意义,对作用模式和研究中存在的问题进行分析,并对其发展前景进行展望。
The antioxidant function of lactic acid bacteria（LAB） in vivo and in vitro has been confirmed through radical scavenging capability,metal chelating activity,reducing power,inhibitory capability of lipid oxidation and the improvement of antioxidant enzyme activity.However,the compositions of lactic acid bacteria and molecular mechanisms of antioxidation have not been elucidated yet.The development of medical healthcare,drugs and anti-aging products through antioxidative lactic acid bacteria will become the hot topic.The significance and current studies of LAB with antioxidant properties have gained tremendous attention at home and abroad.The antioxidant modes and current problems are also discussed,and future development trends of LAB with antioxidant properties are proposed.
