Yeast Cell Wall (Saccharomyces cerevisiae)

Inactivated cell wall of Saccharomyces cerevisiae obtained after autolysis and separation of the soluble intracellular fraction. Delivers both beta-1,3/1,6-glucan (for innate immune activation) and mannoprotein (for pathogen binding) in one product.

Light brown to brown free-flowing powder with a characteristic yeast aroma. Stable through standard pelleting and extrusion temperatures.

We supply feed-grade Yeast Cell Wall from manufacturers in China holding ISO, FAMI-QS, and other certifications relevant to the product and production.

Common market grades include standard yeast cell wall (beta-glucan-cosmetic-grade-oat" class="underline" style="color: var(--sage-deep); text-decoration-color: var(--sage-deep);">beta-glucan ≥ 20 percent, mannan ≥ 20 percent), high-purity grades with elevated beta-glucan, and combined cell wall plus yeast extract products for premium gut health programs.

Bulk and reduced-MOQ shipments. Batch-level COA covering beta-glucan, mannan, protein, ash, moisture, and microbiology.

The Saccharomyces cerevisiae cell wall has two functionally distinct components: an inner beta-1,3-glucan matrix with beta-1,6 branches, and an outer mannoprotein layer rich in mannose-bound proteins. Beta-glucan activates Dectin-1 receptors on macrophages and neutrophils, priming the innate immune response. Mannoproteins bind Gram-negative pathogens through their Type 1 fimbriae and remove them from the gut.

Whole yeast cell wall products deliver both functions in a single ingredient, which is the principal commercial argument over isolated MOS or isolated beta-glucan. Composition varies by strain, growth medium, and processing method, so reputable suppliers report both beta-glucan and mannan content on each batch COA.

The product is produced as a co-product of yeast extract manufacturing (the soluble fraction is sold to the food flavoring industry) or as a primary product from dedicated fermentation. Brewer's yeast cell wall and baker's yeast cell wall have similar but not identical profiles.

Approved as a feed material in the EU, the US, China, and globally.
