With the monitoring of hundreds of pesticides in food and feed, the comminution step is equally crucial as any other to achieve valid results. However, sample processing is often underestimated in its importance and practical difficulty to produce consistent test portions for analysis. The scientific literature is rife with descriptions of microextraction methods, but ironically, sample comminution is often ignored or dismissed as being prosaic, despite it being the foundation upon which the viability of such techniques relies. Cryogenic sample processing using dry ice (−78 °C) is generally accepted in practice, but studies have not shown it to yield representative test portions of <1 g. Remarkably, liquid nitrogen has rarely been used as a cryogenic agent in pesticide residue analysis, presumably as a result of access, cost, and safety concerns. However, real-world implementation of blending unfrozen bulk food portions with liquid nitrogen (−196 °C) using common food processing devices has demonstrated this approach to be safe, simple, fast, and cost-effective and yield high-quality results for various commodities, including increased stability of labile or volatile analytes. For example, analysis of dithiocarbamates as carbon disulfide has shown a significant increase of thiram recoveries (up to 95%) using liquid nitrogen during sample comminution. This perspective is intended to allay concerns among working laboratories about the practical use of liquid nitrogen for improved sample processing in the routine monitoring of pesticide residues in foods and feeds, which also gives promise for feasible test sample size reduction in high-throughput miniaturized methods.

“…Also, a different scientist has used decanol-based SUPRASs for the sample preparation and pre-concentration of pesticides from the environmental and food samples [ 114 , 141 , 142 ]. The fatty acids-based SUPRAS are constructed using short-chain fatty acids as amphiphiles in the aqueous media containing miscible water such as THF [ 143 , 144 ]. The fatty acids contain the carboxyl group (-COOH).…”

“…Different researchers have successfully used medium-chain fatty acid-based SUPRASs for the effective pretreatment of toxic pesticides from the environmental and food samples [ 130 , 144 , 145 ]. Gorji et al [ 143 ] proposed a decanoic acid-based SUPRASs based method for the microextraction and pre-concentration of different types of four organophosphate ( such as diazinon, phosalone, ethion, and chlorpyrifos) and an acaricide (hexythiazox) and isothiazolidine in the rice and vegetables samples. Prior to HPLC-UV analysis, the pesticides samples have been successfully extracted and pretreatment using suitable organic solvent in the small quantity.…”

Supramolecular solvents (SUPRASs) have rapidly gained more attention as a potential substitute to organic solvents in the sample preparation and pre-concentration process. The essential properties of SUPRAS solvents (e.g., multiple binding sites, different polarity microenvironments, the opportunity to tailor their properties, etc.) these qualities offer numerous opportunities to advance innovative sample preparation and pre-treatment platforms compared to the traditional solvents. Among these qualities, certain importance is placed on theoretical and practical knowledge. That has assisted in making significant developments in SUPRAS that advance our understanding of the processes behind SUPRA'S formation. The SUPRA-solute interactions that drive extractions are explored in this context to develop knowledge-based extraction techniques. This review mainly focused on the significant application of supramolecular-based solvents (SUPRASs) in microextraction techniques.SUPRASs-based liquid-phase microextraction (LPME) is an excellent tool for extracting, simple preparation, and pre-concentration from complex environmental samples. SUPRASs-LPME has a wide range of applications for analysing food, environmental samples, pharmaceuticals, and biological samples.
