A sorting method for lemon tea includes obtaining a tea sample from the lemon tea, placing the tea sample into an enclosed container, pre-heating the tea sample in the enclosed container to obtain an volatile sample, absorbing the volatile sample by a adsorption fibers, desorbing the adsorption fibers to obtain a desorbing sample, assaying the desorbing sample in gas chromatography manner to obtain an chromatography outcome, and determining whether the chromatography outcome meets an fresh lemon fragrance conditions.一種檸檬茶飲料的篩選方法,其包括:從檸檬茶飲料取出飲料樣本、將飲料樣本置入密閉容器內、對具有飲料樣本的密閉容器進行預熱提取以產生揮發樣本、利用吸附纖維吸附揮發樣本、對吸附纖維進行脫附程序以取得脫附樣本、將脫附樣本進行氣相層析分析以取得層析結果以及將比對層析結果是否符合新鮮檸檬香芬條件。S211‧‧‧從檸檬茶飲料取出飲料樣本S212‧‧‧將飲料樣本置入密閉容器S213‧‧‧對具有飲料樣本的密閉容器進行預熱提取以產生揮發樣本S214‧‧‧利用吸附纖維吸附揮發樣本S215‧‧‧將吸附纖維以高溫高壓進行脫附程序以取得脫附樣本S216‧‧‧將脫附樣本進行氣相層析分析以取得層析結果S217‧‧‧比對層析結果是否符合新鮮檸檬香芬條件S218‧‧‧允收檸檬茶飲料S219‧‧‧拒收檸檬茶飲料
