| Abstract: | Sodium formaldehyde sulfoxylate in food was tested by direct distillation-titration coupled with AHMT spectrophotometry. To judge the existance of sodium formaldehyde sulfoxylate in food by comprehensive checking of HCHO content and SO_2/HCHO content ratio is accurate and scientific. The indexed rate of recovery and degree of precision in different samples are satisfying. The method can be used to test Sodium formaldehyde sulfoxylate in all foods. |
