| Abstract: | The single wavelength spectrophotometry was used to determine allura red and brilliant blue of blueberry flavor hard candy. Both single wavelength and dual wavelength spectrophotometer were used to determine allura red and tartrazine in orange flavor hard candy. The results showed that allura red at 0. 3 - 40 mg ·L^-1 ,tartrazine at 0.6 - 40 mg·L^-1 and brilliant blue at 0.04-20 mg ·L^-1 had a good linear relationship, with correlation coefficient of larger than 0. 999. The method is simple, convenient and accu- rate. |
