Abstract: |
Food flavor is an important indicator evaluating quality characteristics.Usually,food flavor substances were analyzed by 1D-GC or GC-MS method.But sometimes,it is hard to separate some constituents due to the complexity of components of food flavor and matrices.The second separation of complicated flavor components in food could be realized by comprehensive two dimensional gas chromatography(GC×GC) with better separation ability and analysis speed via the orthogonal combination of two independent columns of different mechanisms.The applications of GC×GC in the analysis of flavor components in edible agricultural products without secondary processing,such as fruits,vegetables and meat,as well as the secondary processed foods including dairy products,drinks and condiments were reviewed.The technical features for GC×GC were also exhibited in this paper, and references were provided for the analysis of food flavor. |
