Microextraction techniques in the analysis of food flavor compounds: A review

Analytica Chimica Acta, 2012
Food flavor compounds due to the complexity of food as a matrix, and usually their very low concentrations in a product, as well as their low odor thresholds, create a challenge in their extraction, separation and quantitation. Food flavor volatiles represent compounds of different polarity, volatility and chemical character, which determine method of ...
