“…Sorbic acid and benzoic acid are commonly used food preservatives with low toxicity and low price allowed to be used all over the world, which can be easily excreted without accumulation [133]. Kim et al [134] investigated the levels of sorbic, benzoic, and propionic acids in fishery products of the South Korean market by HPLC‐photodiode detection array (HPLC‐PDA) and GC/MS.…”

Safety analysis of aquatic products has been a challenge in recent years due to the serious matrix interference, complex characteristics, and ultra-low content of analytes. Introducing advanced materials to sample preparation technique can greatly improve the extraction, enrichment, and separation for further qualification and quantification of target analytes by coupling with consequent analytical technologies. Based on this scope, this review is mainly introducing advanced materials on the sample preparation for safety analysis of aquatic products in the past decade. After introducing the importance of the corresponding advanced materials, advanced materials are used for the sample preparation and in the improvement of safety analysis result of aquatic products. Advanced materials for sample preparation of aquatic products were reviewed including carbon materials, metal organic frameworks, covalent organic frameworks, molecularly/ions imprinted polymers, etc. Then, applications of the advanced materials for the analysis of specific fishery analytes (antibiotics, anesthetic, preservatives, etc.) were briefly introduced. Conclusions and perspectives on advanced materials for sample preparation and safety analysis of aquatic products were also presented.

“…Since its introduction, it has fast become one of the most popular analytical sample preparation techniques because of its advantages such as simplicity, rapidity, and low consumption of solvents and reagents. To date, DLLME has been applied for the analysis of various organic and inorganic pollutants in aqueous samples [18–22], and even in solid samples after an adequate pretreatment [23–25]. …”

A simple and efficient method was established for the determination of synthetic antioxidants in beverages by using dispersive liquid-liquid microextraction combined with high-performance liquid chromatography with ultraviolet detection. Butylated hydroxy toluene, butylated hydroxy anisole, and tert-butylhydroquinone were the antioxidants evaluated. Experimental parameters including extraction solvent, dispersive solvent, pH of sample solution, salt concentration, and extraction time were optimized. Under optimal conditions, the extraction recoveries ranged from 53 to 96%. Good linearity was observed by the square of correlation coefficients ranging from 0.9975 to 0.9997. The relative standard deviations ranged from 1.0 to 5.2% for all of the analytes. Limits of detection ranged from 0.85 to 2.73 ng mL−1. The method was successfully applied for determination of synthetic antioxidants in undiluted beverage samples with satisfactory recoveries.

“…However, the SPME‐coated fibers are considered to be expensive, and for some applications they have limited lifetime. More recent techniques like magic chemisorber (MC) extraction combined with thermal desorption GC or dispersive liquid–liquid microextraction also have been used. However, the MC extraction method needs a thermal desorption procedure prior to GC, and the dispersive liquid–liquid microextraction method is mostly used in simple matrix samples .…”

Derivatization at the injection port following hollow-fiber-based liquid-liquid-liquid microextraction with tetramethylammonium acetate as a dual-function reagent, i.e. an acceptor and derivatization reagent, for the determination of benzoic acid (BA) and sorbic acid (SA) in real samples by GC was developed. BA and SA were extracted from aqueous samples to an organic phase impregnated into the pores of the hollow fiber wall, and then back-extracted to the acceptor solution located inside the lumen of the hollow fiber. Upon injection, the extracted analytes were quantitatively derivatized to their methyl esters with tetramethylammonium acetate in the GC injection port. Several parameters related to the derivatization and extraction efficiency were optimized. The linearity was satisfactory over a concentration range of 0.1-50 mg/L with r > 0.993 for both analytes. The LODs were 2.0 μg/L for SA and 20 μg/L for BA. The recoveries (83-116%) and precisions (RSDs of 1.2-11.4% (n = 3)) were examined by analyzing real spiked samples. The enrichment factors of BA and SA were 300 and 425. The results demonstrated that this is a simple, rapid, accurate, and sensitive method for the determination of BA and SA in various samples.
