Abstract: Increasing the selenium content in tea by biotransformation was of great significance for improving the quality and efficiency of Chinese tea industry and improving the “hidden hunger” of human beings for selenium. The existing literature was systematically combed from the aspects of the content and forms of selenium in soil and tea, the technical standards related to selenium, and the technology of biotransformation of selenium in tea. The artificial selenium enrichment methods of tea were summarized, including application of selenium fertilizer in soil , foliar spraying of selenium fertilizer, application of nano-selenium technology, application of microbial selenium enrichment, and transgenic selenium enrichment technology, etc. Finally, a preliminary prospect and reflection on the research in this field was made. In the future, it was necessary to use quantitative trait loci and other research methods to explore the absorption, transformation and accumulation mechanism of selenium in tea trees, explore new methods for preparing nano-selenium, and strengthen the standardization system construction of selenium-enriched tea.

Key words: tea, selenium, selenium-rich standard, biotransformation of selenium, research progress
