英文摘要:

      Objective To evaluate the testing ability of the inspection agencies for benzoic acid and sorbic acid in meat emulsion. Methods The results of the determination of benzoic acid and sorbic acid were conducted robust statistical analysis, and the ability of detection laboratories was evaluated by Z-ratio. Results The results were tested in 88 laboratories with a satisfaction rate of 77.3%. Conclusions Most of the participating laboratories are satisfied with the test results of benzoic acid and sorbic acid, and laboratories with unsatisfactory results should look for their own causes and correct them.
