Abstract： Thecoreof this experiment lies in using intellgent yellowing equipment to explore the relationship betwen oxygen concentrationand the quality changes of yellow tea by regulating the processfactors such as temperature，humidityand ventilation volume.This studyshows that the oxygen concentration affects thequalityof yellow tea.Oxygen promotes the yellowing reaction，which is conducive to the formation of the "three yellows and one aroma"qualitycharacteristicsofthe yellow tea，including yellowcolorofthedry tea，yellowcolorofthe infusion，yellow colorof the leaf base，corn with a sweet aroma.Slightly increasing the oxygen concentration in the steaming and yellowing environment can help reduce the content of tea polyphenols during the yelowing process，increase the content of amino acids，and enhance the sweetnessand smoothness of the tea soup，giving it a refreshing sensation.During the yellowing process， the color values （ L* a， b* ）of the product were monitored. The analysis reveals thatthe derivedcolorvalues O and Ps werehighly significantly correlated with the total sensory score.This experiment aim tooptimize the yellowing proces，improve the flavor quality of Pingyang yellow tea，and provide technical support for the industrial production of yellow tea.
