Abstract
Hydrophobic bioactive compounds are difficult to deliver because of poor water solubility, limited stability, and uncontrolled release. In this study, chitosan-soy protein isolate (CS-SPI) conjugates were prepared by dry-heat Maillard reaction and used as natural polymeric emulsifiers for curcumin-loaded emulsions. The highest grafting degree of 15.3% was obtained at 70 °C, 74.50% relative humidity, 96 h, and a CS:SPI mass ratio of 1:3. Compared with chitosan and CS-SPI non-covalent complex-stabilized emulsions, the CS-SPI conjugate-stabilized emulsion showed the smallest droplets (7.23 μιη) and a more uniform distribution. It maintained high encapsulation efficiency after 6 days of storage (94.28%) and suppressed burst release during simulated gastric digestion, extending curcumin release to about 72 h. These results suggest that CS-SPI conjugates improve emulsion stability and sustained-release performance.
Curcumin exhibits excellent bioactive potential, but its practical applications in functional foods are limited. In this study, novel food-grade water-in-water (W/W) Pickering emulsions constructed by maltodextrin/pullulan (MD/PUL) were developed to encapsulate and deliver of aqueously dispersible curcumin nanocomplex....

Postharvest spoilage of fresh fruits demands efficient bio-based packaging films. Here, chitosan/gelatin (CG) films were incorporated with β-cyclodextrin-encapsulated clove essential oil microcapsules (β-CD@CEO MCs) at varying loadings. The results suggested that CEO encapsulation occurred within β-CD cavities and hydr...
Developing biodegradable active packaging films that combine mechanical reinforcement, barrier improvement, antibacterial activity, and controlled release of natural antimicrobials remains challenging. Here, TEMPO-oxidized bacterial cellulose (TOBC) was used to stabilize clove essential oil (CEO) Pickering emulsions, w...

Addressing the severe postharvest losses of perishable fruits and environmental concerns caused by plastic packaging, this study developed a multifunctional composite film. Specifically, a composite of β-cyclodextrin and tea saponin-a byproduct of camellia oil processing-was synthesized and served as a stabilizer for t...

In vitro tests indicated that HIPEs enhanced lutein's resistance to storage, heat, and UV exposure while facilitating sustained intestinal release, resulting in a lutein bioaccessibility of 43.73 ± 1.44%.
The escalating need for biodegradable packaging has driven search for sustainable alternatives to synthetic plastics for efficient food products packaging. This research presents a functional gelatin (Gl)-tannic acid (TA)-coated chitosan (Ch) based composite film incorporating mushroom extract (ME) and curcumin extract...
