中文摘要：

该文以黑豆红色素为试验材料,采用分光光度法研究了不同的p H值、反应温度、反应时间、黑豆红色素浓度等条件对亚硝酸盐体外清除作用的影响,确定黑豆红色素体外清除亚硝酸盐的最佳条件。结果表明,黑豆红色素对亚硝酸盐具有较强的体外清除作用,在黑豆红色素浓度为5.5mg/mL、pH为2.6、反应温度为37℃、反应时间为4h时清除率最大,达到了99.50%,高于对照Vc。

英文摘要：

Making Black beans red pigment as material,the influence of different pH,reaction temperature,reac-tion time,black beans red pigment concentration conditions on the nitrite scavenging effect in vitro by spectrophoto-metric method are studied,to ascertain the best condition of black beans red pigment removal of nitrite in vitro. Re-search shows that black beans red pigment of nitrite has strong influence on vitro,while the black beans red pigmentconcentration is 5.5 mg/m L,pH is 2.6,the reaction temperature is 37 ℃,and reaction time is 4 h,clearance reach-es the largest to 99.50%,higher than controls Vc.
