紫外分光光度法测定火腿肠中脱氢乙酸钠

Ultraviolet Spectroscopic measurements ham had Guangdufa Dehydroacetic acid.

目的探讨紫外分光光度法对火腿肠中脱氢乙酸钠的测定方法。方法紫外分光光度法。结果方法的平均回收率为97.2%,变异系数为0.78%,标准曲线y=0.0036x+0.0270,相关系数r=0.9999,最低捡出限为1.0mg/L。结论该方法操作简便、快速、结果可靠、成本低,可作为火腿肠中脱氢乙酸钠的检验方法,也可作为其它食品中脱氢乙酸钠检测的参考。

Objective The Ultraviolet Spectroscopic Guangdufa of ham had used in the measurement methods Dehydroacetic acid. Conclusion The methods of operation simple, convenient, rapid, reliable results, the low cost advantages. The average rate of return method for 97.2% , differentiation factor for the 0.78% standard curve y = 0. 003 6x ＋ 0. 027 0 relevant factor r = 0.999 9 minimum Having limited to 1.0 mg/L.
