中文摘要:

      目的 探讨煮、蒸、炸和微波等4种烹饪方式对草鱼肉中孔雀石绿、结晶紫及其代谢物消减的影响。方法 在空白草鱼肉中添加孔雀石绿、隐色孔雀石绿、结晶紫和隐色结晶紫后, 分别用4种方式烹饪, 采用高效液相色谱串联质谱测定药物的含量。结果 结果表明: 经过炸、微波、煮和蒸等烹饪方法处理后, 鱼肉中的药物浓度分别降低了79.8%~93.7%、69.4%~91.2%、72.0%~86.2%和69.6%~77.8%。相同的烹饪方式, 原药的消减速度均高于代谢物, 药物的消减速率顺序为: 炸>微波>煮>蒸。结论 高温加热能促进孔雀石绿、结晶紫及其代谢产物的消减。

英文摘要:

      Objective To investigate the effects of cooking methods, such as boiling, steaming, frying and microwaving on the reduction of malachite green (MG), crystal violet (CV) and their metabolites in Ctenopharyngodon idellus muscle. Methods Malachite green, cryptochrome malachite green, crystalline violet and cryptochrome crystalline violet were added to the blank grass fish and respectively cooked in 4 ways. The content of the drug was determined by high performance liquid chromatography tandem mass spectrometry. Results The results showed that the 4 cooking methods of frying, microwaving, boiling and steaming reduced the drug concentrations of 79.8%-93.7%, 69.4%-91.2%, 72.0%-86.2% and 69.6%-77.8%, respectively. The degradation rate of the prototype drug was higher than that of the metabolites in the same cooking method. The order of the drug's deceleration rate was: frying>microwaving>boiling>steaming. Conclusion Cooking with high temperature can accelerate the degradation of MG, CV and their metabolites.
