英文摘要:

      Food safety has been an increasingly important public health issue. Gas chromatography (GC) is widely used in food analysis and safety verification with the properties of wide range of applications, fast and efficient analysis. This paper reviewed the type of gas chromatographic columns, development of ionic liquid stationary phase, and the applications of sample pretreatment technologies, such as microwave extraction, supercritical extraction, fast solvent extraction, solid phase extraction, gel chromatography purification, etc. The development of a variety of commonly used gas chromatography detectors, gas chromatography-mass spectrometry (GC-MS) and comprehensive two-dimensional chromatography were simultaneously introduced. The paper also briefly introduced the application of GC in the detection of food additives, food compositions and harmful ingredients. Finally, the development prospects of GC were forecasted.
