Özet
Nowadays, food analysis is more important than ever, because of the changing perspectives on customer behaviours, and enhancement in market expectations. Sample preparation aims to isolate desirable components from sample matrix, due to the inability of most of analytical instruments to handle the sample matrix directly. The physical and chemical properties of a sample and sample compounds of interest have a great influence on the selection of extraction methods. Conventional liquid-liquid extraction (LLE) and solid-phase extraction (SPE) are two of the dominant methods which are used in a wide range of food analysis procedures. Liquid-phase microextraction (LPME) and solid-phase microextraction (SPME) emerged from LLE and SPE, respectively, to overcome the limits and disadvantages of these traditional methods, and to obtain a diverse range of automation and miniaturisation. Microwave-assisted extraction (MAE) and ultrasound-assisted extraction (UAE) are general approaches which are employed to facilitate and enhance the efficiency of solvent extraction techniques.
