Research progress in solid phase microextraction (SPME) in tea aroma analysis

Tea aroma was an important index of tea quality, and the content of aroma in tea was relatively low and its composition was complex. Solid phase microextractoin was a simple and rapid tea aroma compounds extraction method and it was one of research hotspots of tea aroma. In this paper, these tea aroma characteristics combined with recent applications of solid phase microextractoin technology in tea aroma research were reviewed.
