Special Issue Information
Dear Colleagues,
Grapes are one the most consumed fruits worldwide, whether as fresh table fruits or as processed products such as wine, juice, and sauce, among others. It is well known that grapes are a major source of antioxidants, including phenolic compounds, flavonoids, and carotenoids, which can reduce the risk of oxidative damage by scavenging free radicals, oxygen, and chelating catalytic metals. Additionally, by-products of the winemaking industry are particularly rich in polyphenols with important biological activities. Grape pomace is currently only partially exploited for the extraction of seed oil, which is used as an additional source of oil in the pharmaceutical industry due to its pharmacodynamic properties, including antioxidant, antibacterial, hypocholesterolemic, and cytostatic effects, among others. Additionally, grape extracts are a good natural source of antioxidants (i.e., anthocyanin, catechin, epicatechin, resveratrol, proanthocyanidin, etc.) and have anticarcinogenic, anti-inflammatory, and antiproliferative properties when they are included in different drug or cosmetic formulations. Most grape phenolic antioxidants are found in the skin and seeds. Resveratrol, anthocyanins, and catechins are present in grape skins, while procyanidins are concentrated in the seeds. In addition, grape seeds contain significant amounts of polyunsaturated fatty acids, especially linoleic acid.
Polyphenols’ health benefits are overwhelmingly affected by their instability. For this reason, encapsulation techniques and various agents, such as emulsion-based encapsulation techniques and encapsulation in collagen/the organic–inorganic matrix, represent valuable alternatives for the pharmaceutical/cosmetic industry. Microcapsules containing polyphenols as delivery systems for stable and bioavailable compounds represent an additional alternative for natural skin care and cosmetic formulations.
We invite researchers to submit original, innovative research articles and/or reviews that explore the potential of natural compounds from grapes and/or grape by-products to be applied in the medical, cosmetic, pharmaceutical, and/or food fields.

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. Antioxidants 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 2900 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.
