| Abstract: | The optimun factors of determining systhesis pigments in food by UV-spectrophotometry. are studied and the optimun wavelength of these pigments are given. The E Value of each pigment for various wave lengths is measured. The method's relative standard deviation is 3.09% 6.6%, and the recovery is 96.9% 104.2%. |
| Keywords: | Food analysis Synthesis Pigment Ultra-violet spectrophotometer |
