Zymosan is a food-grade insoluble polysaccharide preparation from yeast (Saccharomyces cerevisiae) cell walls, primarily consisting of beta-glucan and mannan, used as an immunostimulant and research reagent.We supply bulk Zymosan sourced from leading China manufacturers, available in powder form for global food and beverage producers. Our Zymosan is widely used in immunology research reagent, complement system activation studies, immune-enhancing food supplements, veterinary products and cosmetic bioactive ingredient.
Zymosan is a crude preparation of yeast cell wall polysaccharides, predominantly β-1,3-glucan and mannan, obtained by alkaline extraction and repeated washing of Saccharomyces cerevisiae.
It is a potent activator of the complement system and innate immunity, widely used in immunology research. In commercial applications, purified zymosan serves as an immune-stimulating ingredient in functional foods, animal health products and cosmetics.
