Special Issue Information

Dear Colleagues,

Food and drug analysis is a diverse and interdisciplinary research area that significantly impacts public health and the economy.

Recent advances in analytical techniques, including chromatography and spectroscopy, have vastly contributed to the accurate and precise analysis of food and drugs. These techniques have been used in various stages in the food and drug industries. Primary spectroscopic techniques revolve around mass spectrometry (MS), nuclear magnetic resonance (NMR), infrared (IR), and ultraviolet-visible spectroscopy (UV-Vis). Major chromatographic techniques include gas chromatography (GC), high-performance liquid chromatography (HPLC), thin-layer chromatography (TLC), and paper chromatography.

This Special Issue of Processes entitled the “Application of Spectroscopy and Chromatography in Food and Drug Analysis and Characterization” aims to publish high-quality research exploring the methods used for food characterization, food adulteration detection, drug characterization and impurity profiling, and drug detection in biological samples. Reviews and original research articles related to the sample preparation, separation, and detection of food and drugs are welcome.

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. Processes 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 2400 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.

A solid-phase microextraction (SPME) injection gas chromatography was validated with the flame ionization detection method (GC-FID) using a capillary column to detect ethanol. The method was used to determine ethanol in fluids with biomedical, clinical, and forensic importance, including water, phosphate-buffered saline (PBS), and artificial sweat. The strategy produced good peak resolution and showed a linear correlation between the concentration and peak areas for ethanol in all matrices. The inter- and intra-day precisions of the method were below 15.5% and 6.5%, respectively, varying according to the matrix. The method achieved detection limits below 1.3 mg/L, varying according to the matrix. Lower limits were obtained for the aqueous solution (0.22 mg/L), followed by the PBS solution (0.96 mg/L), and finally, the sweat solution (1.29 mg/L). This method is easy to perform and suitable for use in routine clinical biochemistry and forensic laboratories, allowing ethanol detection at lower concentrations using lower temperature and time of extraction, when compared with other studies.
