| titleOfInvention | A kind of method for quick of residual sulfur dioxide in food |
| abstract | The invention discloses the method for quick of a kind of residual sulfur dioxide in food, comprise the steps: to extract: take 1 parts by weight of sample in container, it is simultaneously introduced the aerogenesis sheet materials such as the carbonate of 0.1-10 weight portion, bicarbonate or sodium borohydride, 0.05-10 weight portion defoamer, then adding reaction reagent acid, the amount of addition is that sample g/ reagent volume compares ml=1:10-50; Distill in boiling situation, utilize 2-10ml alkaline solution to collect the produced sulfur dioxide gas of distillation; The amount added is sample g/ alkaline solution volume ratio ml=1:2-10; Become collection liquid; (2), detection: take above-mentioned collection liquid in glass detection cell, add metal nanometer sol and the mixing of inorganic salt flocculant afterwards, be then placed in portable Raman spectrometer sensing chamber and detect. Time is short, can realize the rapid screening of batch samples in the inventive method detection; Accuracy is high, and non-false positive phenomenon occurs. |
