Special Issue Information

Dear Colleagues,

Polysaccharides are widely used in biochemical, pharmaceutical, and food industries due to their safety and bioactivity. As a major component of biomass, they play essential structural roles in plants and animals. Polysaccharide composites have garnered an increasing amount of interest for their biodegradability, biocompatibility, and tunable physicochemical properties. Through molecular design—including chemical modification, cross-linking, and hybridization with nanoparticles or synthetic polymers—their mechanical strength, stability, and functionality can be precisely engineered.

These composites have various applications, such as drug delivery systems, food packaging, tissue engineering, and environmental remediation. Advances in green chemistry and nanotechnology further expand their potential, enabling the development of smart, stimuli-responsive materials. However, challenges remain in ensuring their scalability and long-term performance and in optimizing their mechanical, barrier, optical, and functional properties. Currently, research into polysaccharide composites is focused on refining their synthesis methods and broadening their industrial and biomedical applications.

This Special Issue highlights innovative polysaccharide-based materials, covering their synthesis, characterization, and potential uses.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Starch is a promising biodegradable polymer for food packaging, offering a competitive alternative to synthetic films, but its native form has limited functionality. This study aimed to develop edible films based on native (N) and octenyl-succinylated (OS) maize starch incorporating honey-bee-derived extracts (HBE), and to evaluate their physicochemical, structural, and bioactive properties. Moreover, the films were applied as a packaging for apple slices stored for seven days. OS starch enhanced film functionality, particularly when combined with bee pollen, bee bread, and propolis extracts. The presence of amphiphilic octenyl groups and bioactive components significantly modified film microstructure and thermal behavior. Compared to native starch films, OS-based films showed higher water solubility and swelling ratio but lower tensile strength. Among the HBE formulations, propolis-enriched films exhibited the highest total phenolic content, strongest antioxidant capacity, and most effective antimicrobial action. Although none of the starch-based films prevented apple weight loss or browning during storage, propolis addition markedly reduced mold growth compared to synthetic packaging. Overall, octenyl-succinylated maize starch combined with propolis extract offers a promising, biodegradable alternative to conventional plastic films for sustainable food packaging applications.
