Analysis on Proficiency Test of China’s Food Inspection Laboratories in Determination of Benzoic Acid and Sorbic Acid in Tea Beverage

Abstract

Abstract: In order to understand the capability of China’s food inspection laboratories for benzoic acid and sorbic acid determination,Certification and Accreditation Administration of the People s Republic of China(CNCA) organized the proficiency test(PT) of determination of benzoic acid and sorbic acid in tea beverage. 134 laboratories from 31 provinces/cities/municipals took part in the PT. In this paper,the implementation process of the PT was described,including project design,sample preparation,homogeneity and stability test,result statistic and analysis,etc. The resulted showed that 80.6% laboratories have satisfactory results in benzoic acid determination,and 84.3% ones have satisfactory results in sorbic acid determination. In conclusion,most laboratories taking part in the PT have good competence in analyzing benzoic acid and sorbic acid.

Key words: tea beverage, benzoic acid, sorbic acid, proficiency test(PT)
