Method | Solvent | Advantages | Disadvantages | References |
---|---|---|---|---|
QuEChERS | Acetonitrile, acetonitrile/acetic acid, acetonitrile/citric acid, acetonitrile/formic acid | Fast, simple, economical, reproducibility and applicability | Low enrichment factor in extracts of lipophilic compounds and the need for original modifications of the procedure | [53,54,55] |
LLE | Hexane, cyclohexane | Effective for small-scale preparations | Does not provide a sufficiently clean analyte in all cases, time-consuming, possible loss of sample by adsorption onto the glassware | [45,49,56] |
SLE | Acetonitrile/water, methanol/water | Smaller volumes of solvent | SLE alone can be not satisfactory to extract some mycotoxins without interference and additional purification steps are usually needed | [47,49] |
PLE | Acetonitrile/water, acetonitrile/methanol |
Extraction process can be automated, higher extraction efficiency in shorter time, lower amount of extraction solvent | High instrument price | [47,49,57] |
SFE | supercritical CO2 fluid, acetonitrile | Fast, small solvent volumes, extraction of temperature sensible analytes | Low recoveries, high concentrations of co-extracts, high costs | [45,49] |
