| 摘 要： | 综合研究了测定食品中吊白块常用的3种方法:乙酰丙酮法、变色酸法、盐酸苯肼法。结果表明:乙酰丙酮法的检出限为0.08μg.mL-1,标准曲线的线性范围为2.5~3.5μg(r=0.999 2),呈色稳定性好,精密度为2.5%。并用该方法检测黑龙江地区大米粉中甲醛含量,通过甲醛和二氧化硫的含量判断吊白块的存在。

| Abstract: | The formaldehyde sulfoxylate of food by using tacetylacetone ethod,chromotropic acidmethod and phenylhydrazine hydrochloride method was studied.The result indicated that the acetylacetone method picked out limits was 0.08 μg·mL-1,specification curve＇s linearity range was 2.5~3.5 μg（r=0.999 2）,colored stability to be good,the accuracy was 2.5%.The method was used to examine the formaldehyde content of rice flour in Heilongjiang area to judge the formaldehyde sulfoxylate existence according to formaldehyde and sulphur dioxide content. |
