“…The rapid injection of the extraction and dispersive solvent mixture into the aqueous sample produces a rapid emulsification of oil droplets in water. Equilibrium can be achieved in a matter of seconds and presence of the many oil droplets constitutes a large surface area for extraction of the analyte of interest from the aqueous phase (Lv et al 2013;Vasil et al 2012). Sample pre-treatment and pre-concentration is an important step prior to sample analysis.…”

“…The extraction solvent used in ST-DLLME must have properties of low water solubility and is capable of extracting the analyte of concern (Vasil et al 2012). Extraction solvents should also be either of higher or lower density than water such that when phase separation is induced, it can be easily withdrawn for further analysis.…”

“…The disperser solvents used in DLLME should be miscible with both the extraction solvent and the aqueous phase (Vasil et al 2012). Its role is in dispersing the extraction solvent as tiny oil droplets in the emulsification stage thus creating a large surface area to enable the rapid transfer of analytes into the extraction solvent (Çabuk et al 2012).…”

“…The organic analytes present in the aqueous medium rapidly migrate to the extraction solvent, because of the large contact surface between the organic and the aqueous phases. After phases separation, the organic phase with the analytes of interest is collected and analysed by an appropriate technique [31][32][33]. DLLME has been applied for the determination of OTA in wine by HPLC-MS [34], cereals by HPLC-FL [35], and patulin in apple juices by CE-UV [36].…”

Mycotoxins are toxic secondary metabolites produced by different fungi, with different chemical structures. Mycotoxins contaminate food, feed, or raw materials used in their production and cause diseases and disorders in humans and livestock. Because of their great variety of toxic effects and their extreme heat resistance, the presence of mycotoxins in food and feed is considered a high risk to human and animal health. In order to ensure food quality and health consumers, European legislation has set maximum contents of some mycotoxins in different matrices. However, there are still some food commodities susceptible to fungal contamination, which were not contemplated in this legislation. In this context, we have developed new analytical techniques for the multiclass determination of mycotoxins in a great variety of food commodities (some of them scarcely studied), such as cereals, pseudocereals, cereal syrups, nuts, edible seeds, and botanicals. Considering the latest technical developments, ultrahigh performance liquid chromatography coupled to tandem mass spectrometry has been chosen as an efficient, fast, and selective powerful analytical technique. In addition, alternative sample treatments based on emerging methodologies, such as dispersive liquid-liquid microextraction and QuEChERS, have been developed, which allow an increased efficiency and sample throughput, as well as reducing contaminant waste.

“…Porém, várias publicações já relataram seu uso para análise de alimentos, frutas, vegetais, assim como amostras biológicas e ambientais (ANDRUCH et al, 2012). Todavia, para realização da DLLME em amostras complexas como o plasma, um pré-tratamento da matriz como precipitação proteica, ultrafiltração, diluição e centrifugação é necessário (REZAEE; YAMINI; FARAJI, 2010; SARAJI; BOROUJENI; BIDGOLI, 2011).…”
