The invention discloses a method for distinguishing the high temperature yeast. The flavor components of the yeast are analyzed by a head space solid phase microextraction technology and a gas chromatography-mass spectrography technology, and the quality of the yeast is distinguished by analyzing data by a judgment and analysis method. According to the method provided by the invention, a head space solid phase microextraction sample injection method is optimized; and the optimal condition of analyzing the flavor substances of the yeast is obtained. The method of the invention is scientific, rational, high in accuracy, high in feasibility and high in repeatability and sensitivity and can effectively distinguish samples under judgment analysis; and the correctness is over 95 percent. |
