Special Issue Information

Dear Colleagues,

Functional foods contain a variety of beneficial components, having a positive impact on human health and well-being by targeting specific physiological functions in the body. With an unprecedented level of attention on health and well-being, the discovery and application of functional food have progressed significantly through cutting-edge technologies.

Based on this, this Special Issue intends to gather a selection of reviews and original research papers dealing with emergent and innovative applications for functional foods. Topics include, but are not limited to, the following:

  • Investigating the role of functional foods in preventing and managing chronic diseases such as cardiovascular disease, diabetes, and obesity;
  • Enhancing the bioavailability and efficacy of functional ingredients through improving food technology, formulation, or novel delivery systems;
  • Discovery of bioactive compounds and their biochemistry.

Dr. Sanggil Lee
Guest Editor

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. Applied Sciences 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 2400 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • Reprint: MDPI Books provides the opportunity to republish successful Special Issues in book format, both online and in print.

The aim of this study was to develop biodegradable pectin films enriched with anthocyanin-rich fruit juices and evaluate their functional properties. Films were prepared with bilberry and blackcurrant juices, and their color response to pH, mechanical performance, thermal stability, and water vapor permeability were analyzed. The incorporation of juices significantly affected the films’ color, with ΔE values ranging from 8.41 to 39.24 for blackcurrant and 36.60 to 59.59 for wild bilberry juice, showing clear visual differences. Increasing juice concentration from 5% to 10% enhanced color intensity and opacity, with the highest opacity (12.90 a.u./mm) observed for films containing 2% pectin and 10% bilberry juice. Mechanical testing indicated reduced tensile strength after juice addition, with the lowest elongation (11.90%) noted for films with 2% pectin and 5% blackcurrant juice. The lowest water vapor permeability (7.43·10−11 g/m·s·Pa) was recorded for films with 2% pectin. Thermal analysis revealed greater mass loss in juice-enriched films (40–44.5%) compared to controls (37.6%), reflecting the presence of volatile compounds. pH testing confirmed the films’ indicator function, with red coloration at pH 2 and shifts toward blue-grey (bilberry) or orange-green (blackcurrant) at pH 8. These findings demonstrate that pectin films enriched with dark red fruit juices exhibit promising potential for smart food packaging applications. Full article

The health-promoting, preventive, protective, and therapeutic applications of the natural compound sulforaphane (SF) produced from its biogenic precursor in broccoli, glucoraphanin, are extremely well established. SF has been the subject of thousands of studies and over 125 clinical trials. The many mechanisms of action of SF in mammalian systems have been extensively documented. SF is the most potent naturally occurring inducer of the Keap1/Nrf2 pathway, which is most well-known for its upregulation of antioxidant and detoxification mechanisms and activation of pathways resulting in the inhibition of inflammation. Much of this regulation involves the various hormonal axes of the body. However, the influence of SF on hormone-mediated health conditions remains unexplored in recent scholarly reviews. This review aims to address this gap by exploring many of these interactions, with a focus on the health and wellness issues specific to both females and males. Full article
