摘　　要：用偶氮氧化物AAPH热分解生成的自由基引发脂质氧化,通过硫氰酸铁法和硫代巴比妥酸反应物法检测脂质的氧化进程,研究腐植酸钠在用非离子表面活性剂Tween 20稳定的葵花油水包油乳状液模拟非均相食品体系和用大豆磷脂脂质体模拟非均相生物体系中的抗氧化活性。结果表明:在葵花油乳状液中0.20、0.50、1.00 mg/mL腐植酸钠和在大豆磷脂脂质体中0.016、0.040、0.080 mg/mL的腐植酸钠均具有抗氧化活性。The oxidation of lipids was initiated by free radicals generated by AAPH thermal decomposition, and the oxidation process of lipids was detected by ferric thiocyanate and thiobarbituric acid reactants. The antioxidant activities of sodium humate in heterogeneous food systems simulated by non-ionic surfactant Tween 20 stabilized sunflower oil-water emulsion and soybean phospholipid liposomes were studied. The results showed that sodium humate in sunflower oil emulsion(0.20, 0.50,1.00 mg/mL) and soybean phospholipid liposomes(0.016, 0.040, 0.080 mg/mL) had antioxidant activity.
