Advances on the Extraction and Separation Technologies in Tea Aroma Components Research

Abstract:

Study on the tea aroma components is greatly significant, which are important factors in tea quality valuation.In recent years, nine main methods are under consideration：simultaneous distillation and solvent extraction, vacuum distillation extraction, steam distillation under reduced pressure, headspace analysis, solid-phase micro-extractions, headspace solid-phase micro-extractions, tea liquid absorption, supercritical fluid extraction and electronic nose. Meanwhile, advantages and disadvantages of each method were analyzed, in order to conduct technological guidance on the extraction and separation technologies in tea aroma components and provide a theoretical basis in improvement of each method.
