Special Issue Information
Dear Colleagues,
One major and growing portion of the world's food production is the generation of food by-products. While these by-products pose challenges, they offer a unique opportunity as low-cost, renewable, and abundant resources for extracting natural bioactive compounds. However, the challenge lies in identifying the most efficient extraction processes that preserve the integrity of these sensitive bioactive compounds. Traditional extraction techniques often degrade the quality and potency of these components, making it critical to explore alternative approaches. Emerging green technologies—such as microwave-assisted extraction, ultrasound-assisted extraction, etc.,—are increasingly being recognized for their ability to overcome these limitations, offering innovative and sustainable solutions.
Despite the benefits, even these novel techniques must be applied correctly to optimize the quality of the extracted compounds. Achieving this requires careful attention to various process aspects, including the extraction parameters (e.g., choice of solvent, temperature, solid–liquid ratio, etc.), sample preparation methods, and the implementation of pre- and post-treatments. In this respect, developing more effective and sustainable extraction processes is essential to fully realize the potential of novel technologies.
This Special Issue aims to fill the gap in the literature by sharing cutting-edge knowledge on optimizing these processes and utilizing food by-products. We invite you to contribute your research articles, communications, or reviews exploring novel bioactive compounds extraction processes from food by-products.

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. Separations 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 2600 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.
