“…Huang et al [157] established a combination of DART-MS, gas analysis-mass spectrometry (EGA-MS), and heart-cut EGA-gas chromatography (GC)/MS to characterize the chemical composition of Chinese crude propolis and showed that some flavonol glycosides, phenolic glycerides, and beeswax were easily pyrolyzed at 300-550 • C. Flavonoids with a larger molecular weight, such as quercetin (m/z 301) and rhamnose (m/z 315), cannot be detected using EGA-MS and heart-cut EGA GC/MS because of their strong polarity and high boiling points. Rýdlová et al [158] combined the DART technique with TOF-MS. Determining and quantifying compounds characteristic of different cocoa products (theobromine, caffeine, phenols, and flavonoid compounds) were achieved by optimizing the ionization mode, ionization temperature, and solvent type of sample extraction.…”

Flavonoid compounds have a variety of biological activities and play an essential role in preventing the occurrence of metabolic diseases. However, many structurally similar flavonoids are present in foods and are usually in low concentrations, which increases the difficulty of their isolation and identification. Therefore, developing and optimizing effective extraction and detection methods for extracting flavonoids from food is essential. In this review, we review the structure, classification, and chemical properties of flavonoids. The research progress on the extraction and detection of flavonoids in foods in recent years is comprehensively summarized, as is the application of mathematical models in optimizing experimental conditions. The results provide a theoretical basis and technical support for detecting and analyzing high-purity flavonoids in foods.

“…Regarding analytical innovations, a non-chromatographic rapid method by Direct analysis in real time (DART) time-of-flight MS (DART-TOF-MS) was used to quantify some phenolic acids, flavonoids, and xanthines [ 78 ]. As a proof of concept, the method was applied to cocoa powder and instant cocoa beverages, observing a good separation between both types of samples.…”

Cocoa and its derivative products, especially chocolate, are highly appreciated by consumers for their exceptional organoleptic qualities, thus being often considered delicacies. They are also regarded as superfoods due to their nutritional and health properties. Cocoa is susceptible to adulteration to obtain illicit economic benefits, so strategies capable of authenticating its attributes are needed. Features such as cocoa variety, origin, fair trade, and organic production are increasingly important in our society, so they need to be guaranteed. Most of the methods dealing with food authentication rely on profiling and fingerprinting approaches. The compositional profiles of natural components –such as polyphenols, biogenic amines, amino acids, volatile organic compounds, and fatty acids– are the source of information to address these issues. As for fingerprinting, analytical techniques, such as chromatography, infrared, Raman, and mass spectrometry, generate rich fingerprints containing dozens of features to be used for discrimination purposes. In the two cases, the data generated are complex, so chemometric methods are usually applied to extract the underlying information. In this review, we present the state of the art of cocoa and chocolate authentication, highlighting the pros and cons of the different approaches. Besides, the relevance of the proposed methods in quality control and the novel trends for sample analysis are also discussed.

“…Conventionally, analysis of PFAS is performed utilizing LC-MS/MS techniques. ,− While these methods are highly sensitive and allow effective separation of isomeric species and quantification, alternative techniques such as direct ambient mass spectrometry (AMS) can enable higher sample throughput, which is ideal for screening purposes . The plasma-based AMS technique direct analysis in real time (DART) enables high throughput screening and quantification of various classes of molecules for both positively and negatively ionized species. − Furthermore, there has been recent interest in the DART analysis of PFAS, with results from Cody and Maleknia demonstrating robust ng/L level quantification of PFOA and the screening of various other PFAS such as PFOS, using coated glass capillaries (CGCs) with octadecylamine as an extraction phase for PFAS . In fact, many developed AMS methods benefit from analyte preconcentration prior to instrumental analysis. , Previous work from our research group has demonstrated the use of solid phase microextraction (SPME) devices composed of hydrophilic–lipophilic balance–weak anion exchange particles embedded in polyacrylonitrile (HLB-WAX/PAN) as an ideal strategy for the preconcentration of multiple classes of PFAS, allowing sub-ng/L detection when coupled with LC-MS/MS. , …”

Per-and polyfluoroalkyl substances (PFAS), an emerging class of toxic anthropogenic chemicals persistent in the environment, are currently regulated at the low part-per-trillion level worldwide in drinking water. Quantification and screening of these compounds currently rely primarily on liquid chromatography hyphenated to mass spectrometry (LC-MS). The growing need for quicker and more robust analysis in routine monitoring has been, in many ways, spearheaded by the advent of direct ambient mass spectrometry (AMS) technologies. Direct analysis in real time (DART), a plasma-based ambient ionization technique that permits rapid automated analysis, effectively ionizes a broad range of compounds, including PFAS. This work evaluates the performance of DART-MS for the screening and quantification of PFAS of different chemical classes, employing a central composite design (CCD) to better understand the interactions of DART parameters on their ionization. Furthermore, in-source fragmentation of the model PFAS was investigated based on the DART parameters evaluated. Preconcentration of PFAS from water samples was achieved by solid phase microextraction (SPME), and extracts were analyzed using the optimized DART-MS conditions, which allowed obtaining linear dynamic ranges (LDRs) within 10 and 5000 ng/L and LOQs of 10, 25, and 50 ng/L for all analytes. Instrumental analysis was achieved in less than 20 s per sample.
