摘要: 采用Schaal烘箱法研究了氯化亚铁、苏氨酸铁螯合物、TBHQ及不同浓度苏氨酸铁螯合物对动植物油脂的抗氧化作用。实验结果表明,苏氨酸铁螯合物在添加剂量为0.5g/kg水平以上,对油脂具有催化自动氧化酸败的作用;但在油脂中添加剂量为0.1g/kg时能有效的降低油脂的过氧化值,表现出一定的抗氧化能力。Abstract: This experiment was studied the antioxidant activity of lipids with ferrous chloride, iron threonine chelate, TBHQ and the different concentration of iron threonine chelate by the method of Schaal oven. The results indicated that it could catalyze oxidation of lipids to rancidity when the dosage of the iron threonine chelate was more than 0.5g/kg. However, it could effectively reduce the peroxide value at the dosage of 0.1g/kg.
