Ultrasound-assisted assembly of Auricularia auricula-judae polysaccharide–soy protein isolate nanoparticles: The effect of extraction methods on functional properties
This study compared the emulsifying properties and in vitro anti-inflammatory activity of black fungus polysaccharides (AAP) extracted by ultra-high-pressure-assisted extraction (UHP) and hot water extraction (HWE). UHP-AAP exhibited improved emulsifying performance, with an emulsifying activity index (EAI) of 0.62 m2/g and emulsifying stability index (ESI) of 79.85 min, together with enhanced anti-inflammatory activity. Using UHP-AAP and soy protein isolate (SPI), composite nanoparticles (A-S NPs) were fabricated via ultrasound-assisted self-assembly. The optimized A-S NPs (AAP/SPI = 1:1, 300 W, 10 min) showed a particle size of 318 nm, a ζ-potential of −43 mV, and a PDI of 0.2136. Hydrogen bonding, electrostatic attraction, and hydrophobic interactions promoted molecular rearrangement and network formation, improving colloidal and thermal stability. These nanoparticles possess good thermal stability and dispersibility, making them suitable as functional food carriers.
To valorize Pleurotus eryngii mycelium protein (PeMP) as a sustainable protein source, this study investigated the efficacy of ultrasound-assisted extraction (0-450 W) in simultaneously enhancing the extraction yield and modulating the physicochemical properties of PeMP. Results showed that ultrasound treatment at 150 ...

Background: Fucoidan is a sulphated polysaccharide from brown seaweed with reported antioxidant activity, but its high molecular weight and hydrophilicity limit its incorporation into food matrices. Method: To address this, fucoidan was encapsulated in a water-in-oil-in-water (W1/O/W2) double emulsion (FuD) prepared by...
