Antioxidants from Agrofood Wastes for Cosmetic Industry: Insights into Green Extraction Approaches

Dear Colleagues,

In recent decades, concerns related to food by-products and their associated environmental problems have arisen as challenges for agrofood industries, governments, and civil society. It is estimated that 88 million tonnes of food waste are annually generated in the EU, with associated costs of 143 billion euros. Most of these residues are not transformed due to technical limitations or difficulties in market access, meaning solutions to deal with this problem are urgently needed. These topics make researchers aware of the bioactive composition of food wastes and of the possibility to obtain new active ingredients. The extractive process is the most critical step. Conventional extraction has long been applied to the recovery of bioactive compounds from natural sources, but this technique has limitations. Alternative greener extraction technologies, such as Subcritical Water Extraction (SWE), Supercritical Fluids Extraction (SFE) or Ultrasound-Assisted Extraction (UAE), have emerged as more sustainable and effective.

This Special Issue intends to explore the extraction of food by-products with antioxidative activity using eco-friendly techniques, aiming to reuse them as new cosmetic ingredients. Special attention will be given to in vitro, ex vivo and in vivo studies, mathematical models to optimize extraction procedures and deep insights into the characterization of bioactive compositions using analytical methodologies (such as HPLC-DAD, HPLC-MS, LC–MS, HPLC–MS and NMR). Regulatory review papers are welcome.

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-anonymized 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.
