Special Issue Information

Dear Colleagues,

Food-derived polysaccharides and oligosaccharides have emerged as key bioactive components in modern food science due to their diverse structures, functional versatility and potential to support the development of healthier and more sustainable food systems. Advances in extraction, enzymatic modification and biotransformation technologies have expanded the pathways for producing tailored carbohydrate polymers with enhanced physicochemical and biological properties. These molecules play crucial roles in regulating food texture, stabilizing colloidal systems, modulating starch digestion and interacting with proteins and other nutrients during processing. Despite significant progress, challenges remain in establishing clear structure–function relationships, achieving precise and efficient production and conducting comprehensive functional evaluations. Variability introduced by processing and the intrinsic complexity of polysaccharide structures further complicate scientific and industrial applications. Therefore, innovative analytical tools, green processing technologies and mechanistic studies are urgently needed. This Special Issue aims to highlight recent advances in the production, characterization, modification and functional assessment of food-derived polysaccharides and oligosaccharides. We hope that contributions from the scientific community will deepen our understanding of these essential biopolymers and drive forward their application in functional foods and advanced food technologies.

The objective of this study was to explore the effect of the assembly sequences of wall materials on the structure and properties of Antarctic krill peptide (AKP)-loaded ovalbumin (OVA)–chitosan (CS) nanoparticles (NPs). Two AKP-loaded NPs (CS/OVA-AKP and OVA/CS-AKP) were prepared by changing the sequences of OVA and CS. The results confirmed that CS/OVA-AKP had a smaller particle size (291 nm vs. 320 nm), lower polydispersity index (0.233 vs. 0.282), higher absolute zeta potential (34.4 mV vs. 32.1 mV), and higher encapsulation efficiency (81.6% vs. 75.4%) than OVA/CS-AKP. X-ray diffraction analysis confirmed that AKP was encapsulated in an amorphous state within the NPs. Fourier transform infrared spectroscopy and three-dimensional (3D) fluorescence spectroscopy revealed that electrostatic interactions, hydrogen bonding, and hydrophobic interactions were the primary driving forces for nanoparticle formation, with CS/OVA-AKP demonstrating a stronger OVA fluorescence quenching effect. Compared with OVA/CS-AKP, CS/OVA-AKP exhibited better redispersibility, and CS/OVA-AKP showed greater stability under various environmental factors (thermal treatment, salt concentration, pH, and storage time). During simulated gastrointestinal digestion, CS/OVA-AKP effectively protected AKP from gastric degradation and showed a higher AKP release rate in simulated intestinal fluid (61.1%) than OVA/CS-AKP (53.0%). The release followed the Korsmeyer–Peppas model, with OVA/CS-AKP exhibiting non-Fickian diffusion (n = 0.7500), and CS/OVA-AKP approached Case II transport (n = 0.9889), indicating erosion-controlled release behavior. CS/OVA-AKP also demonstrated higher hypoglycemic activity, with inhibition rates of 41.1%, 37.5%, and 36.1% for α-glucosidase, α-amylase, and DPP-IV, respectively. These findings underscore the important influence of wall-material assembly sequences on the structure and properties of AKP-loaded NPs, offering valuable insights for the development of bioactive peptide delivery systems.
