Research Progress on Detection Methods and Current Status of Residual Pyrrolizidine Alkaloids in Tea
This article reviewed the detection methods for the residual pyrrolizidine alkaloids(PAs)in tea,including colorimetric methods,capillary electrophoresis,immunological methods,chromatographic analysis,and discussed their current status and future trends.Additionally,it summarized the current research on PAs residues in tea both domestically and internationally,analyzed the toxic effects of PAs in tea,and examined the limit standards of existing PAs globally.Considering the lack of detection standards for PAs in Chinese tea,it is urgent to develop detection standards for at least 21 types of PAs,in accordance with the European Union regulations.Furthermore,research on monitoring the con-tamination levels of PAs in tea and conducting risk assessments is crucial.In order to ensure the quality and safety of tea in our country and actively respond to EU trade barriers,strong technical support was provided.
