    TLDR Combining polysaccharides with alginate improves protection and release of pumpkin seed protein in digestion.
    The study explores the use of composite alginate-based hydrogels to deliver antioxidant pumpkin seed protein hydrolysate (PSPH) in simulated gastrointestinal conditions. It finds that incorporating polysaccharides like Aloe vera, CMC, and tragacanth into alginate enhances encapsulation efficiency, with CMC-alginate achieving the highest at 85.07%. These composites provide better control over the release rate and maintain higher antioxidant stability during digestion compared to plain alginate. The research concludes that these hydrogels improve the stability and delivery of bioactive compounds, suggesting their potential application in the food industry for functional foods.
