Suitable planting systems are critical for the physicochemical and bioactivities of strawberry (Fragaria × ananassa Duch.) polysaccharides (SPs). In this study, SPs were prepared through hot water extraction, differences in characteristics between derived from elevated matrix soilless strawberries (EP-SP) those conventional soil (GP-SP) investigated. A higher extraction yield was observed EP-SP (5.88%) than GP-SP (4.67%), slightly values measured average molecular weight (632.10 kDa vs. 611.88 kDa) total sugar content (39.38% 34.92%) EP-SP. contrast, a protein (2.12% 1.65%) more ordered arrangement exhibited by GP-SP. Monosaccharide composition analysis revealed that contained levels rhamnose (12.33%) glucose (49.29%), whereas richer galactose (11.06%) galacturonic acid (19.12%). Thermal indicated only minor decomposition temperatures (approximately 225-226 °C) thermal stability samples. However, showed enthalpy change (ΔHg = 18.74 J/g) compared to (13.93 J/g). Biological activity assays generally exerted stronger non-enzymatic glycation inhibition at both early final stages (IC50: 7.47 mg/mL 7.82 11.18 11.87 mg/mL, respectively), effective against intermediate α-dicarbonyl compounds (maximum 75.32%). Additionally, superior α-glucosidase (IC50 2.4583 mg/mL), line with kinetic fluorescence quenching analyses showing enzyme-substrate complex binding affinity (Kis 1.6682 mg/mL; Ka 5.1352 105 M-1). Rheological measurements demonstrated solutions pronounced increase apparent viscosity concentrations (reaching 3477.30 mPa·s 0.1 s-1 70 mg/mL) shear-thinning behavior, while comparatively lower network order. These findings suggest different significantly affect structures functionalities SPs, demonstrating enhanced hypoglycemic anti-glycation properties. It is therefore recommended suitable be selected optimize functionality plant-derived potential applications food pharmaceutical industries.

To extract oil, the fruits of Idesia polycarpa Maxim (IPM) must first undergo a drying process. This study aimed to investigate how different industrial techniques-microwave vacuum (MVD), microwave drying, infrared and hot air drying-affect structural characteristics bioactivities IPM cake meal polysaccharides (IPMPs). The results revealed significant differences in structure composition four IPMPs. MVD-IPMP, dried using MVD, exhibited lower molecular weight (346.26 kDa), higher uronic acid content (30.74 %), distinct triple-helix structure. These features contributed its enhanced antioxidant activity, α-glucosidase inhibition, prevention glycation. IPMPs induced secondary conformational changes α-glucosidase, leading decreased enzyme activity. Additionally, caused static quenching enzyme's intrinsic fluorescence, suggesting specific interaction mechanism, with MVD-IPMP demonstrating highest binding affinity. findings suggest that MVD is an effective technique for large-scale production high-quality
