Special Issue Information

Dear Colleagues,

In the last decade, the study of functional foods has experienced enormous growth due to their positive effects on human health attributed to some of the bioactive compounds they contain. Products such as red berries, cocoa and dark chocolate, pulses, tea, wine, fresh fruits, garlic, red pepper, turmeric, ginger, and curry are rich in active phytochemicals, including carotenoids, flavonoids, phenolic acids, stilbenoids, coumarins, indoles, lignans, organosulfures, saponins, anthraquinones, and ginsenosides that may help to prevent some diseases.

This featured Special Issue of Separations is entitled “Characterization of Functional Foods by Chromatographic and Electrophoretic Methods”. The topic is focused on the analysis of functional foods by chromatographic and electrophoretic methods, also covering sample pretreatments for the recovery and purification of active molecules. Furthermore, the identification and structural elucidation of unknown compounds with potential bioactivity using chromatography coupled to tandem mass spectrometric will be of interest.

Manuscripts submitted to this issue will undergo a rigorous peer review process, and decisions will be taken based on reports from independent reviewers.

Best regards,

Prof. Dr. Javier Saurina

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Separations is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Flavanols are a class of polyphenols that have become the focus of much research because of their medicinal properties. For this paper, a new method to determine polyphenols in nutraceutical samples was developed, based on solid-liquid extraction and further analysis by liquid chromatography. Analytes were recovered by ultrasound-assisted extraction, using a mixture of methanol/water/hydrochloric acid (70:29:1, v:v:v) as the solvent. Reversed-phase high-performance liquid chromatography with ultraviolet/visible (HPLC-UV/Vis) and fluorescence detection (HPLC-FLD) were developed to determine the content of the principal flavanols. The HPLC-FLD method showed better selectivity and sensitivity, so it was selected for further studies. The analytical parameters established with FLD were satisfactory in terms of linearity (R2 ≥ 0.993), repeatability (RSD% ≥ 2.2), and limits of detection of 0.1 mg L−1 or below. The nutraceutical samples were analyzed by HPLC-FLD to determine the compositional profiles of flavanols, then they were subsequently treated using chemometric methods, such as principal component analysis (PCA). Results showed that the study of compositional profiles from the selected flavanols was sufficient for description and discrimination purposes. The cranberry samples were the richest in flavanols, procyanidin A2 being the principal flavanol, and artichoke samples the least rich. Full article
