Abstract: The preliminary study results showed that taking 0.6% to 1.2% pectinase to extract flavor compounds from pickled Alliium chinense at pH 3.4 and 50 ℃for 2 h to 4 h, the higher allicin yield, juice yield and content of soluble solid are attained, which are from 0.21g/100 ml to 0.27 g/100 ml, from 90% to 92% and from 19.2 Brix to 19.8 Brix, respectively. Meanwhile, the specific aroma of Alliium chinense is kept well.
