Plant Materials and Their Antioxidant Potential

Dear Colleagues,

In the human body, there are mechanisms that have developed to protect against damage caused by oxidation reactions. These include a variety of compounds, endogenous and exogenous, that work synergistically to neutralise free radicals. These components may be dietary antioxidants (tocopherols, ascorbic acid, carotenoids, polyphenols), antioxidant enzymes (superoxide dismutase, glutathione reductase) or metal ion-binding proteins (lactoferrin, albumin). It is necessary to find viable solutions for the production of basic food products with the widest possible use, which, in addition to a longer life cycle, also ensure a healthy lifestyle. Fruit is an integral part of the human diet, providing a range of essential constituents for human health, such as vitamins and minerals. The use of by-products from the food processing industries is an indispensable and challenging task across the globe. The most abundant by-products from the minimal processing of fruits and vegetables are the peel and seeds, and these are reported to contain high amounts of phenolic compounds with antioxidant and antimicrobial properties.

The use of extracts with antioxidant potential from fruit and vegetable waste in the production of food ingredients, functional foods, nutraceuticals, pharmaceuticals and cosmeceuticals can ensure the development of new methods for processing fruit and vegetable waste and by-products; the use of bioprocessing and biorefining to transform fruit and vegetable wastes and by-products into value-added foods; and the development of new food, cosmetic and pharmaceutical products based on bioactive extracts from food and fruit and vegetable waste. In this Special Issue, we invite researchers to provide original research and review articles that relate to antioxidants and human health. We welcome papers from researchers in a wide range of fields, such as the food industry and the fields of biotechnology, physiology, biochemistry, medicine and nutrition. The aim of this Special Issue is to provide a valuable collection of new knowledge in this field.

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 250 words) can be sent to the Editorial Office for assessment.

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.
