摘　　要：为降低亚硝酸盐的添加对乳化肠安全品质的影响,研究磷酸化亚硝基血红蛋白(phosphorylated nitrosohemoglobin,P-NHb)替代亚硝酸钠(NaNO_(2))对乳化肠的色泽、抗氧化能力和感官品质等的影响。结果表明,随贮存时间的延长,P-NHb对乳化肠挥发性盐基氮的影响与NaNO_(2)无显著差异(P>0.05);添加P-NHb可减少乳化肠pH值下降;P-NHb组亚硝酸盐残留量最高为(6.22±0.01)mg/kg;P-NHb组和NaNO_(2)组的硫代巴比妥酸反应物值最高分别为(0.62±0.01)mg/kg和(0.67±0.01)mg/kg,表明P-NHb能够抑制脂肪氧化,其抗氧化效果优于NaNO_(2);P-NHb可赋予乳化肠理想色泽;P-NHb组整体可接受度与NaNO_(2)组无显著差异(P>0.05)。综上所述,P-NHb可改善乳化肠色泽,降低亚硝酸盐残留,具有较强的抗氧化作用,可以作为一种新型天然色素,考虑其代替NaNO_(2)在肉制品中使用。In order to reduce the negative effect of nitrite addition on the safety and quality of emulsified sausage,the effects of phosphorylated nitrosohemoglobin(P-NHb)as a sodium nitrite(NaNO_(2))substitute on the color,antioxidant capacity and sensory quality of emulsified sausage were studied.The results showed that with the extension of storage time,the inhibitory effect of P-NHb on total volatile base nitrogen was not significantly different from that of NaNO_(2)(P>0.05).The addition of P-NHb inhibited the decrease in the pH of emulsified sausage.The highest residual nitrite in the P-NHb group was(6.22±0.01)mg/kg.The highest thiobarbituric acid reactive substances(TBARS)values in the P-NHb and NaNO_(2) groups were(0.62±0.01)mg/kg and(0.67±0.01)mg/kg,respectively,indicating that P-NHb can inhibit lipid oxidation,and its antioxidant effect is better than that of NaNO_(2).P-NHb endowed emulsified sausage with ideal color.Furthermore,there was no significant difference in the overall acceptability between the P-NHb and NaNO_(2) groups(P>0.05).In summary,P-NHb can improve the color of emulsified sausage,reduce its residual nitrite and have a strong antioxidant effect.Therefore,it can be used as a new natural pigment and considered as a NaNO_(2) substitute in meat products.
