Special Issue Information
Dear Colleagues,
It is well known that dietary proteins provide a rich source of biologically active peptides that can be released through hydrolysis by proteolytic enzymes or fermentation. Bioactive peptides have exhibited various beneficial functional activities, in vitro and in vivo, such as antioxidant, anti-inflammatory, anti-thrombotic, anti-osteoporosis activities, etc. However, the question remains: how can we prepare protein hydrolysates with high levels of bioactivity? The use of technology to degrade proteins in a bioenzyme-directed manner is the key to the preparation of highly bioactive peptide ingredients. Furthermore, hydrolysates are complex mixtures of peptides with different lengths and amino acid compositions, including large non-functional peptides, non-degraded proteins, and free amino acids. Hence, fractionation technologies are required to separate peptides from hydrolysates in order to concentrate the desired bioactive or functional peptides. Moreover, what is the amino acid sequence of the bioactive peptides inside? And how effective is it in cell-based or in animal experiments? All of these issues need to be further clarified, and the relevant research may help develop bioactive peptides as functional ingredients in the food industry.

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. Foods is an international peer-reviewed open access semimonthly 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.
