Special Issue Information

Dear Colleagues,

The analysis of foods is always an emerging trend in food chemistry. In recent years, novel trends grew through method development and instrumentation setup. Moreover, novel “holistic” approaches, mainly through the -omics approach, were developed. The development, application and usage of spectroscopic methods in the analysis of foods reveals valuable and important information.

Through several approaches, from “classical” spectroscopic methods for the analysis of selected constituents to either targeted or untargeted -omics analysis, the constituents’ content and chemical structure is revealed, and scientific tools can bridge the above information to other factors such as quality, chemical transformation and safety assurance. The above factors are highly important for a plethora of reasons: from the food safety and the additive value in food constituents to geographical origin and species analysis.

The current Special Issue deals with the above mentioned factors for two selected major classes in the food chain: “Milk and Dairy products” and “Olive oil”. The analysis of milk and its products, as well as olive oil, is of major importance, and spectroscopic analysis, focused mainly on NMR spectroscopy, can contribute to address the following factors: origin and originality, constituents, bioactive substances, beneficial effects, and food safety.

Review articles and original research papers which focus on the above factors are warmly welcomed.

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. Molecules is an international peer-reviewed open access semimonthly 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 2700 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.

Abstract
A multi-residue method was developed to identify and quantify pharmaceutical drug residues in full-fat milk, using a modified QuEChERS extraction procedure and sonication combined with Ultra-High-Performance Liquid Chromatography–High-Resolution Orbitrap Mass Spectrometry (UHPLC-HR-Orbitrap-MS). Sample preparation involves three different QuEChERS extraction procedures and sorbents for [...] Read more.
A multi-residue method was developed to identify and quantify pharmaceutical drug residues in full-fat milk, using a modified QuEChERS extraction procedure and sonication combined with Ultra-High-Performance Liquid Chromatography–High-Resolution Orbitrap Mass Spectrometry (UHPLC-HR-Orbitrap-MS). Sample preparation involves three different QuEChERS extraction procedures and sorbents for the purification step. The optimized modified extraction method, combined with the clean-up approaches using C18 and the EMR-Lipid sorbent, has been validated in terms of linearity, recovery, precision, LOD and LOQ, matrix effects (ME) and expanded uncertainty. The optimized method showed a linearity >0.9903, recoveries within the range 65.1–120.1%, precision (expressed as %RSD) <17.5%, medium (<39.9%) to low (<16.7%) matrix effects and acceptable expanded uncertainty (<33.1%). Finally, the proposed method was applied to representative real samples of milk (by local markets), revealing the existence of one pharmaceutical drug (imidocarb) in one sample. Full article
