Abstract Four Allium vegetables were processed by common cooking methods and
refrigeration in different time periods after cooking. VB1, VB2 and VC contents before and after cooking and refrigeration were measured by GB. The results indicated that different cooking methods could bring different effects on contents of 3 kinds of vitamins. Frying caused the smallest loss of vitamins and steaming had the biggest loss. 3 kinds of vitamins had different degrees of loss during refrigeration. The longer the refrigerated period, the bigger loss of vitamin.
