Food, Beverage and Aroma Analysis Gas Chromatography ...

Home / Food, Beverage and Aroma Analysis Gas Chromatography. Flavor Analysis. Most of what is perceived as flavors in foods are actually the aromas and odors that are being detected by our sense of smell. The human nose is far more sensitive to most flavor and odor compounds than are GCMS systems, so proper detection, identification and quantitation of these

GC-O-MS technique and its applications in food flavor

Gas chromatography-olfactometry-mass spectrometry (GC-O-MS) is a combination of gas chromatography-olfactometry (GC-O) and gas chromatography-mass spectrometry (GC-MS). GC-O-MS technique is a powerful tool to study food flavors and it has been widely applied for aroma and flavor analysis of various food items. In combination with different technologies,
