Headspace sorptive extraction (HSSE) and stir bar (SBSE), two recently introduced solventless enrichment techniques, have been applied to the analysis of headspace Arabica roasted coffee brew itself. In both HSSE SBSE is performed on a thick film poly(dimethylsiloxane) (PDMS) coated onto magnet incorporated in glass jacket. Sampling done by placing PDMS (gas phase or HSSE) immersing it liquid (liquid SBSE). The then thermally desorbed on-line with capillary GC-MS. performance compared...
Abstract This article provides a critical overview of current methods to quantify essential oil components. The fields application and limits the most popular approaches, in particular relative percentage abundance, normalized concentration true amount determination via calibration curves, are discussed detail. A specific paragraph is dedicated correct use widely used detectors analyte response factors. set applications for each approach also included illustrate considerations. Copyright ©...
Abstract This article is a short overview of the state art in essential oil analysis. Several aspects analysis oils and volatile fraction vegetable matrices are here critically discussed. The following topics dealt with: steam distillation, hydrodistillation headspace sampling for sample preparation, fast‐GC, fast‐GC–qMS analysis, enantioselective GC, multidimensional GC techniques GC–isotopic ratio mass spectrometry (GC–IRMS) quantitation.
Food quality is a multifaceted, evolving concept encompassing various aspects throughout the production chain. The shift from traditional analytics to comprehensive strategies driven by need meet this extended definition. Foodomics, specifically focusing on connecting chemical composition sensory properties, vital for comfort foods like coffee, cocoa, and tea, chosen enjoyment rather than nutrition. In foodomics, larger more complex datasets demand Artificial intelligence-based tools...
The unceasing evolution of analytical instrumentation determines an exponential increase data production, which in turn boosts new cutting-edge challenges, requiring a progressive integration artificial intelligence (AI) algorithms into the instrumental treatment software. Machine learning, deep and computer vision are most common techniques adopted to exploit information potential advanced chemistry measures. In this paper, our primary focus is on elucidating remarkable advantages...
A new approach for sorptive enrichment of analytes from the headspace aqueous or solid samples, referred to as extraction (HSSE) is described. The technique implies sorption volatile and semivolatile compounds into a large amount polydimethylsiloxane (ca. 50 mg) placed on glass rod support. (PDMS) coated fixed in head closed vial erlenmeyer sample equilibrated 30–60 min. PDMS bar then thermally desorbed on-line with capillary gas chromatography–mass spectroscopy (GC–MS). Using phase highly...
A new sampling technique, Headspace Sorptive Extraction (HSSE), is here applied for the first time to headspace of medicinal and aromatic plants. The analyte partition coefficient between HSSE-PDMS stir bar sample (K1), concentration factor (CF), reproducibility, minimum recoverable amount were determined by analyzing standard solution high volatility C5–C7 compounds with different polarities structures (cyclohexane, propyl acetate, hexanal, 1-hexen-3-ol, isoamyl 2-heptanol). Four plants,...
This study investigates chemical information of volatile fractions high-quality cocoa (Theobroma cacao L. Malvaceae) from different origins (Mexico, Ecuador, Venezuela, Columbia, Java, Trinidad, and Sao Tomè) produced for fine chocolate. explores the evolution entire pattern volatiles in relation to processing (raw, roasted, steamed, ground beans). Advanced fingerprinting (e.g., combined untargeted targeted fingerprinting) with comprehensive two-dimensional gas chromatography coupled mass...
