Special Issue "Intensification Technologies to Efficiently Extract Antioxidants from Agro-Food Residues"
A special issue of Antioxidants (ISSN 2076-3921). This special issue belongs to the section "Extraction and Industrial Applications of Antioxidants".
Deadline for manuscript submissions: 31 December 2020.
As is well known, there is an increasing interest in recovering phytochemicals from agricultural, forestry, and food industry residues, aiming to reduce their environmental impact and improve sustainable economic growth in the bioeconomy scheme. These phytochemicals can be employed widely in food and feed, food supplements, and cosmetics products, among others, thanks to their bioactivity properties, such as antioxidant, antimicrobial, etc.
The recovery of bioactive compounds from vegetal matrices involves several steps, where an adequate pre-treatment and extraction are of foremost importance. Conventional solid–liquid extraction is the technique of choice at industrial scale. Its main drawbacks are the high solvent consumption and long extraction times that may degrade thermolabile phytochemicals, due to the relative high temperature required to improve mass transfer. Additionally, the fact that some bioactive molecules, i.e., polyphenols, have internal cell localizations or are bounded to cell wall polysaccharides limits the extraction yield.
Therefore, industrial sustainability of recovery of phytochemicals from agro-food wastes will benefit from the implementation of intensified processes covering the use of solvents with improved properties (pressurized and supercritical fluids, deep eutectic solvents or hydrotropes), nonconventional energies (microwave, ultrasound, pulsed electric) or high static pressure. All these technologies, which are being studied at laboratory and pilot scale, aim to develop highly efficient methods for the extraction of phytochemicals according to the “Green Engineering principles”.
As guest editor, I cordially invite you to contribute to this Special Issue by submitting original research articles and review papers according to your notable expertise in the efficient extraction of phytochemicals from agro-food wastes.
I am also pleased to report that Antioxidants has an Impact Factor of 4.520 (Journal Citation Reports®, 2019) and ranks 10th out of 135 (Q1) titles in the category ‘Food Science & Technology’, 6th out of 61 (Q1) in ‘Chemistry, Medicinal’, and 63rd out of 298 (Q1) ‘Biochemistry & Molecular Biology’.
If you have any questions, please do not hesitate to contact me. Feel free to forward this email to researchers from all around the world with expertise in this topic.
I look forward to hearing from you.
Dr. Soraya Rodriguez-Rojo
