| Abstract: | This experiment was carried out according to the national standard GB/T 5009.34—2003 The Determination of Sulfites in Foods. A Kjeldahl distillation instrument (BUCHI K—355,Swiss) was used. The results showed that there was no significant difference (p<0.05) compared with the method under the traditional distillation instrument, and had good precision. The relative standard deviation (RSD) of the results was between 1.63%~3.60% and the recovery was between 91.05%~102.95%. |
