“…Since the adsorption capacity of a single coating is too limited, it has become a sensible norm to hybrid GO with other materials such as MOFs, organic compounds, and inorganic compounds. So far, GO has successfully detected polychlorinated biphenyls [55], Volatile organic compounds [56], bisphenol A [57], phenols [58], nerolidol [59], cadmium ion [60], and PAHs [61]. A hybrid composite of an iron-based MOF and GO was synthesized and a satisfying result was obtained in the extraction of phthalic acid esters from vegetable oil [62].…”

The materials used for the fabrication of solid-phase microextraction fiber coatings in the past five years are summarized in the current review, including carbon, metal-organic frameworks, covalent organic frameworks, aerogel, polymer, ionic liquids/poly (ionic liquids), metal oxides, and natural materials. The preparation approaches of different coatings, such as sol-gel technique, in-situ growth, electrodeposition, and glue methods, are briefly reviewed together with the evolution of the supporting substrates. In addition, the limitations of the current coatings and the future development directions of solid-phase microextraction are presented.

“…In particular, in milk SPME has been exploited in different coatings. The MOF-based coating was prepared for the analysis of bisphenol A [177], commercial fibers were used to assay organochlorine pesticides [178] and PAHs [179], whereas graphene-based fiber was fabricated for the determination of PCBs [180]. A very interesting approach for the analysis of contaminants in complex matrices was developed by Deng et al [29].…”

The present review aims to describe the recent and most impactful applications in pollutant analysis using solid-phase microextraction (SPME) technology in environmental, food, and bio-clinical analysis. The covered papers were published in the last 5 years (2014–2019) thus providing the reader with information about the current state-of-the-art and the future potential directions of the research in pollutant monitoring using SPME. To this end, we revised the studies focused on the investigation of persistent organic pollutants (POPs), pesticides, and emerging pollutants (EPs) including personal care products (PPCPs), in different environmental, food, and bio-clinical matrices. We especially emphasized the role that SPME is having in contaminant surveys following the path that goes from the environment to humans passing through the food web. Besides, this review covers the last technological developments encompassing the use of novel extraction coatings (e.g., metal-organic frameworks, covalent organic frameworks, PDMS-overcoated fiber), geometries (e.g., Arrow-SPME, multiple monolithic fiber-SPME), approaches (e.g., vacuum and cold fiber SPME), and on-site devices. The applications of SPME hyphenated with ambient mass spectrometry have also been described.

“…Different odor characteristics of the brine samples from different fermentation periods and manufacturers can be observed, and the research of the fingerprints of volatile flavor compounds in the brine samples helps to optimize quality control of these products. As an advanced analytical technique to analyze flavor compounds in food samples, headspace solid‐phase microextraction/gas chromatography–mass spectrometry (HS‐SPME/GC‐MS) has many advantages, such as easy to perform, solvent free, sensitive, and selective (Canellas, Vera, & Nerín, ; Lv et al., ; Wang et al., ; Xiao et al., ; Xu & Jiang, ). However, the use of this method in the analysis of organic volatile flavor compounds in southern stinky tofu brine has been very limited, because the research of organic volatile flavor compounds is a very difficult task (Chao, Tomii, Watanabe, & Tsai, ; Liu, Chen, Sun, & Huang, ).…”

It is difficult to produce southern stinky tofu, a famous traditional Chinese snack, at industry scale due to the complex composition of its brine. In this study, the fingerprints of organic volatile flavor compounds in the southern stinky tofu brine samples from five manufacturers were studied using headspace solid‐phase microextraction/gas chromatography–mass spectrometry (HS‐SPME/GC‐MS) with the aid of chemometric methods. The fingerprints were obtained by HS‐SPME/GC‐MS and analyzed with the time shift alignment method, Shannon entropy, correlation coefficient, and principal component analysis. The results show that the time shifts in the samples can be accurately corrected by the time shift alignment method despite unexpected interferences. The fingerprint information was evaluated by Shannon entropy, while the similarities and differences in the fingerprints were investigated by correlation coefficient. Moreover, the identification of stinky tofu manufacturers can be achieved by principal component analysis. The predominant volatile compounds in southern stinky tofu brines were indole, 3‐methylindole, phenol, and 4‐methylphenol. Therefore, the established fingerprinting of volatile compounds for the brines by combining HS‐SPME/GC‐MS with chemometric methods was a simple and reliable method.
