Special Issue Information

Dear Colleagues,

Polyphenols and polysaccharides are two major bioactive components in food resources, widely recognized for their nutritional value and diverse biological activities. From a sustainable and developmental perspective, the synchronous extraction of polyphenols and polysaccharides has attracted increasing attention as an efficient and eco-friendly strategy to improve resource utilization and reduce processing waste. Compared with conventional separate extraction, co-extraction approaches can preserve molecular integrity, enhance polyphenol–polysaccharide interactions, and improve functional properties. Moreover, co-extracted polyphenol–polysaccharide complexes often exhibit enhanced antioxidant, enzyme inhibitory, and health-promoting activities, highlighting their potential for functional food and nutraceutical applications. This Special Issue focuses on recent advances in extraction techniques, interaction mechanisms, structural characteristics, and bioactivities of co-extracted polyphenols and polysaccharides from food materials and by-products.

Blue honeysuckle (Lonicera caerulea L.) berries are rich in bioactive compounds, yet their efficient utilization is limited by conventional single-component extraction methods. This study developed a one-step ultrasound-assisted synchronous extraction (OUE) method to simultaneously recover polysaccharides and polyphenols and evaluate their physicochemical properties and bioactivities. OUE-extracted polyphenols (OUEP) and polysaccharides (OUES) showed significantly stronger antioxidant activity, with higher DPPH and ABTS radical scavenging capacities than conventionally extracted polyphenols (MPP) and hot water extraction followed by alcohol polysaccharides (HPS). FTIR analysis indicated similar polysaccharide backbones for OUES and HPS, while SEM revealed a more porous microstructure in OUES, and rheological measurements showed higher apparent viscosity, suggesting improved macromolecular interactions and functional behavior in food systems. Additionally, OUEP displayed strong α-amylase and α-glucosidase inhibitory activities (IC50 = 25.85 ± 1.77 and 26.08 ± 0.11 mg/mL, respectively), highlighting their potential for glycemic control. These findings demonstrate that OUE not only enables efficient, simultaneous recovery of multiple bioactive components but also enhances their structural and functional properties, supporting the development of health-promoting food products and improving the utilization of blue honeysuckle berries.
