【摘要】 对宜春市场上5个品种的酱油用原子吸收分光光度法进行了8种无机元素含量的测定。结果表明:样品1、2、3号中Ca的含量比4、5号高很多;样品1号含Mg量最高;样品1号含Cu量最高,2号含Cu量最少,其他几种含量差不多;样品1号中Fe的含量较高,而2、3、4、5号含量相对较低,不及人体所需的正常值;样品1、2号Zn含量远大于3、4、5号样品,其中1号样品最高;5个样品Mn、Cr的含量相差不多,均不含有Cd;样品4、5号中Pb的含量远大于1、2、3号样品。由此可知,1、2、3号酱油的品质比4、5号酱油好。更多还原

【Abstract】 Eight inorganic elements in five soy brands were investigated by atomic absorption spectrometry at Yichun city.Result showed that Ca contents in sample 1,2 and 3 were higher that that in sample 4 and 5.Mg and Cu contents in sample 1 were the highest.And sample 2 had the lowest Cu content.Sample 1 showed higher Fe content than sample 2,3,4 and 5,which was lower than the normal need of human body.Zn contents in sample 1 and 2 were much more than that in sample 3,4 and 5,among which Zn content in sample 1 was the highest.Mn and Cr contents in all the five samples were almost the same and did not contain Cd.Pb contents in sample 4 and 5 were far more than that in sample 1,2 and 3.Therefore,Soy quality of sample 1,2 and 3 were better than that of sample 4 and 5.更多还原
