The objective of this research was to study the effect of the antioxidants, delta-tocopherol, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), tertiary butylhydroquinone (TBHQ), and propyl gallate in a model system of lean muscle and canola oil and to compare the effects with those in minced herring. Two carrier solvents with different dielectric constants (epsilon), ethanol (epsilon = 24) and oil (epsilon= 2), were used. Oxidation was measured using thiobarbituric acid reactive substances (TBARS) and sensory analysis. In both the lean muscle-canola oil model system and in herring muscle, the hydrophilic antioxidants, propyl gallate and TBHQ, were more effective in providing oxidative stability than the lipophilic antioxidants, delta-tocopherol and BHT. The oxidative stability of a cod muscle-canola oil system in the presence of propyl gallate, and delta-tocopherol was not affected by the dielectric constant of the carrier solvent, while BHA was more effective as an antioxidant when added in the polar solvent ethanol.
本研究的目的是在瘦肌肉和菜籽油的模型体系中研究抗氧化剂δ-生育酚、丁基羟基茴香醚（BHA）、丁基羟基甲苯（BHT）、叔丁基对苯二酚（TBHQ）和没食子酸丙酯的效果，并将这些效果与鲱鱼碎肉中的效果进行比较。使用了两种具有不同介电常数（ε）的载体溶剂，乙醇（ε = 24）和油（ε = 2）。使用硫代巴比妥酸反应性物质（TBARS）和感官分析来测量氧化情况。在瘦肌肉-菜籽油模型体系和鲱鱼肌肉中，亲水性抗氧化剂没食子酸丙酯和TBHQ在提供氧化稳定性方面比亲脂性抗氧化剂δ-生育酚和BHT更有效。在没食子酸丙酯和δ-生育酚存在的情况下，鳕鱼肌肉-菜籽油体系的氧化稳定性不受载体溶剂介电常数的影响，而当BHA添加到极性溶剂乙醇中时，其作为抗氧化剂的效果更显著。
