摘　　要：为了研究软枣猕猴桃蛋白酶提取液的抗氧化性能和它对亚硝酸盐的清除作用。本实验测定不同浓度的软枣猕猴桃蛋白酶提取液对亚硝酸钠和DPPH的清除能力。并向蛋白酶提取液中添加了一定浓度的抗坏血酸和丁羟基茴香醚,测定它们之间协同作用的抗氧化性能和清除亚硝酸盐能力。试验结果表明,软枣猕猴桃蛋白酶提取液的抗氧化性能和对亚硝酸盐的清除能力都与浓度呈正相关。软枣猕猴桃蛋白酶提取液可有效清除亚硝酸盐,并具有一定的抗氧化能力。The purpose of this study is to research the scavenging activity on sodium nitrite investigated and the remove ability of DPPH free radical and sodium nitrite.Meanwhile ,to add a surely concentration of Vc and BHA in the enzyme extract,evaluating the synergistical among them. The results showed that the scavenging activity and antioxidative ability were positively correlated with the concentration ration of Actinidia arguta. The conclusion of this study is actinidia arguta can effectively remove the sodium nitrite and anti-oxidation.
