Special Issue Information
Dear Colleagues,
As the food industry evolves toward more sustainable, circular, and health-conscious models, transforming agrifood waste into functional ingredients represents a powerful strategy with which to address environmental challenges and public health needs. Agrifood by-products—often discarded or undervalued—are rich sources of bioactive compounds such as polyphenols, known for their antioxidant potential and capacity to reduce oxidative stress and neutralise reactive oxygen species (ROS).
This Special Issue aims to highlight recent scientific and technological advancements in the upcycling of agrifood by-products into antioxidant-rich ingredients with functional and nutraceutical potential. We encourage contributions that explore green and sustainable extraction technologies, novel analytical methods for the characterisation of bioactive compounds, and the development of innovative functional foods and nutraceuticals. We are particularly interested in studies investigating the modulation of oxidative stress and ROS-related pathways, as well as their role in personalised nutrition, metabolic regulation, and chronic disease prevention. Research on encapsulation techniques and innovative delivery systems to enhance the bioavailability and stability of antioxidant compounds is also welcome. Furthermore, studies assessing the safety, efficacy, shelf-life, and consumer acceptance of such formulations are highly encouraged.
This Special Issue welcomes original research articles and in-depth reviews that position agrifood wastes and by-products as key resources for health-promoting innovation.

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.
