European markets have implemented the Commission Regulation (EU) Number 1146/2014 of 23 October 2014 of the MRL for Anthraquinone (9,10-AQ) is 0.02 ppm. After this implementation for 9,10-AQ for tea in the European market, there has been a decreased by 33.6% in Indonesian tea exports. This paper will explain the preliminary study results of 9,10-AQ in Indonesian tea that consist of (1) the results of 9.10- AQ content of Indonesian tea samples, (2) 9,10-AQ content on fresh tea shoot and in each stage of tea processing, (3) the content of 9.10-AQ in tea liquor, and (4) results of antioxidant activity analysis of Indonesian tea in free radical scavenging by DPPH analysis (1,1-diphenyl-2-picrylhidrazyl). Samples selection selected from West Java and East Java as center of tea producing province in Indonesia with incidence of high 9,10-AQ levels in tea. The results show that the 9,10-AQ content depend on drying system technologies. The data conclude that 9,10-AQ level increase due to withering process by 0.004 ppm and in drying process it increase higher (0.007 ppm). The data of 9,10-AQ level of tea liquor are all below the MRL, therefore brewed tea is safe for health. Antioxidant activity of Indonesian tea with 9,10-AQ level above the MRL (0.043 ppm) is very strong that very potential to reduce the negative effects of tea contaminants by free radicals scavenging.
