采用二安替比林甲烷比色法测定几种休闲食品中TiO2的含量。几种休闲食品经硫酸-硫酸铵消解完全后，在强酸介质中钛与二安替比林甲烷形成黄色络合物，选用420 nm作为测定波长，用分光光度法测定休闲食品中TiO2的含量，采用标准曲线法定量。结果表明：不同品牌同一类型膨化食品中TiO2的含量都比较接近，且都低于1 g/kg；同一品牌不同类型膨化食品中TiO2的含量差异较大，但均未超过国家食品添加剂使用限量。

In this article, it adopts DAPM colorimetric method to determine the content of titanium dioxide in the several snacks. After the snacks used in the experiment are completely digested in sulfuric acid and ammonium sulfate digestion, the titanium and two diantipyryl methane form the yellow complex, using 420 nm as the measured wavelength and the spectrophotometric method to determine the content of titanium dioxide of snacks , and standard curve method also being used. The result shows that:the content of Titanium dioxide in the same type of snacks within different brand is similar, less than 1 g/kg;the content of Titanium dioxide in the same brand snacks within different type is difference, none of the content of titanium dioxide of these snacks mentioned above exceeds the national standard consumption of food additives.
