accelerated solvent extraction and gas chromatography mass spectrometry for determination of polycyclic aromatic hydrocarbons in Smoked Food samples
Journal of Agricultural and Food Chemistry, 1999Co-Authors: Guangdi Wang, Monique Lewis, Burde Kamath, Renita K ArcherAbstract:Accelerated solvent extraction (ASE) is a new sample extraction method offering a number of advantages such as low pe -extraction cost, reduced solvent and time consumption, and simplified extraction protocols. In this study, the ASE method was applied to the extraction of polycyclic aromatic hydrocarbons (PAHs) from biological samples. For recovery studies, fish tissues and ground pork were used as sample matrices. Sample aliquots fortified with 16 PAHs were extracted by ASE, and the extracts were treated with sulfuric acid and Florisil, followed by gas chromatography-mass spectrometry analysis. The PAH recoveries by the ASE method were found to be comparable with or better than those by Soxhlet extraction. The extraction and quantitation method was then applied to the determination of PAHs in several Smoked meat samples obtained from a local market. Up to 12 PAHs were found to be present at concentrations ranging from 3 to 52 ng/g wet sample.

Deep eutectic mixture membrane-based microextraction: HPLC-FLD determination of phenols in Smoked Food samples.
Food chemistry, 2019Co-Authors: Andrey Shishov, Svetlana Gagarionova, Andrey BulatovAbstract:Abstract A novel approach for effective sample pretreatment of Food was developed. This approach was based on in situ deep eutectic mixtures formation between analytes (hydrogen bond donors) and choline chloride (a hydrogen bond acceptor) supported in a hydrophilic porous membrane. By this action, the analytes were extracted and retained into the hydrophilic porous membrane. Finally, the hydrophilic porous membrane containing the analytes was transferred into an aqueous phase and back-extraction occurred due to deep eutectic mixture decomposition in the aqueous phase. The developed approach was applied to the HPLC-FLD determination of phenols (phenol, o-cresol, p-cresol, eugenol, isoeugenol and guaiacol) in Smoked Food samples. The limits of detection, calculated from a blank test based on 3σ, were 0.3 µg kg−1 for phenol, o-cresol, p-cresol; 0.6 µg kg−1 for eugenol, isoeugenol; and 1 µg kg−1 for guaiacol.

A novel flow injection chemiluminescence method for automated and miniaturized determination of phenols in Smoked Food samples
Food chemistry, 2017Co-Authors: Christina Vakh, Ekaterina Evdokimova, Aleksei Pochivalov, Leonid Moskvin, Andrey BulatovAbstract:An easily performed fully automated and miniaturized flow injection chemiluminescence (CL) method for determination of phenols in Smoked Food samples has been proposed. This method includes the ultrasound assisted solid-liquid extraction coupled with gas-diffusion separation of phenols from Smoked Food sample and analytes absorption into a NaOH solution in a specially designed gas-diffusion cell. The flow system was designed to focus on automation and miniaturization with minimal sample and reagent consumption by inexpensive instrumentation. The luminol - N-bromosuccinimide system in an alkaline medium was used for the CL determination of phenols. The limit of detection of the proposed procedure was 3·10-8·molL-1 (0.01mgkg-1) in terms of phenol. The presented method demonstrated to be a good tool for easy, rapid and cost-effective point-of-need screening phenols in Smoked Food samples.

Chemometric Discrimination Between Smoked and Non-Smoked Paprika Samples. Quantification of PAHs in Smoked Paprika by Fluorescence-U-PLS/RBL
Food Analytical Methods, 2016Co-Authors: Olga Monago-maraña, Teresa Galeano-díaz, Arsenio Muñoz De La PeñaAbstract:This study presents a strategy for differentiating paprika obtained by means of different drying systems. The differentiation is performed using spectroscopic fluorescence in combination with multivariate analysis. The two groups of samples (Smoked or non-Smoked paprika) are classified according to the content of some of their fluorescent compounds presented in each group, among which several polycyclic aromatic hydrocarbons (PAHs) are included. These compounds are characteristic in Smoked Food. The full information of excitation–emission matrices (EEMs) is processed with the aid of unsupervised parallel factor analysis (PARAFAC), PARAFAC supervised by linear discriminant analysis (LDA) and discriminant unfolded partial least squares (DU-PLS). The last algorithm allows an adequate classification of unknown paprika samples. Besides, the quantification of several PAHs in paprika was performed by means of unfolded partial least squares with residual bilinearization (U-PLS/RBL). On this way, three (fluorene, phenantrene, and anthracene) out of the five (fluorene, phenantrene, anthracene, pyrene and chrysene) selected analytes were quantified.
