Detection and Analysis of Citrinin and Nitrite Content in the Salted Fish from Southeast of Guizhou
Objective:To investigate the levels of citrin and nitrite in pickled fish in southeast Guizhou province,and to provide reference for the food safety of pickled fish.Method:Pickled fish made by farmers in Rongjiang county and Congjiang county in southeast Guizhou province were collected,and the content of citrin in the samples was determined by fluorescence spectrophotometry,and the nitrite content in the samples was determined by visible spectrophotometry of naphthalene ethylenediamine hydrochloride.Result:A total of 60 pickled fish samples were tested,and the average content of citrin was 0.1725 μg·kg-1 and 1.3820 mg·kg-1.The contents of citrin and nitrite in Rongjiang county and Congjiang county were compared,and the difference was not statistically significant(P＞0.05).Conclusion:The contents of citrindicin and nitrite in the pickled fish samples were low,and neither of them exceeded the requirements of the national food safety limit standard.
