Special Issue Information
Dear Colleagues,
Stable isotopes of carbon, oxygen and hydrogen are used internationally to record food adulteration. The authenticity of wine, vinegar, oil and the products that include them can be detected using stable isotope analysis. The adulteration in wine and vinegar is usually carried out by adding industrial alcohol and/or sweeteners (beet or cane sugar). Based on European Community Directives, stable carbon isotopes (13C/12C) encompass the most suitable analytical tool to detect the adulteration of wine with industrial alcohol, a petroleum derivative. The addition of sugars increases the product's sugar content through fermentation. However, the isotopic composition of wine differs from that of sugar cane but can easily match that of sugar beet. Samples of vinegar and oil were tested with stable isotopes and the range of values determines the potential adulteration. Samples of oils were also collected and analysed using 13C and 18Ο to detect any impurities with other oils, as in the case of wine.

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. Applied Sciences 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 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.
