添加金属Fe3+对阿勒泰羊尾脂氧化初期脂肪酸的变化影响
Influence of Fe3+ in lipid oxidation and fatty acids in Altay sheep fat during initial autoxidation stage
摘要
Abstract
Influence of Fe3 + with different content in lipid oxidation and fatty acids in Altay sheep fat during initial autoxidation stage were investigated.The result showed that after 0.05 mol/L Fe3+ treatment of fat,the pH was around 6.4 (p ＜0.05),TBARS value did not reach the 0.5 mg MDA/kg(p ＜ 0.05),the rate of oxidation was decreased slowly.After treatment 0.05 mol/L Fe3+ group,saturated fatty acid content was increased by 43.46％,the content of monounsaturated fatty acids was decreased by 10.87％,the content of polyunsaturated fatty acid was decreased by 0.78％,0.05 mol/L Fe3+ can be used as a reference concentration to reduce and inhibit fat rancidity and oxidation rate.关键词
