Bioligical contamination of Pu'er tea in a Guangzhou tea market
摘要
Abstract
OBJECTIVE: To understand the level of bioligical contamination by toxins including aflatoxinB1(AFB1), FumonisinB1(FB1), DON and T-2 toxins of Pu'er tea in a tea market of Guangzhou,China, to provide useful information and data for safety and related health standards. METHODS: Sample 70 Pu'er tea randomizely in a Guangzhou tea market. All the samples were assayed with ELISA kit for FB1, DON, T-2 toxin, and with immunoaffinity chromatography-high performance liquid chromatography for AFB1. RESULTS: The AFB1 level of 8 among 70 samples was above the limit of national standard(5 μg/kg), and the DON level of 63 samples above the national standard(1 mg/kg),while the levels of FB1 and T-2 toxin were within the standards(1 mg/kg and 100 μg/kg, respectively). CONCLUSION:AFB1 and DON in our samples were higher and exceeded the allowed standards to some degree. Althouth the levels of FB1 and T-2 were within eimits below, their existence in Pu'er tea should require close attention.关键词
