Forest-Derived Fungal Active

Oyster Mushroom Extract
Polysaccharide 10-30% Powder

Step into an autumn woodland where rain has softened a fallen hardwood log, and a fan-shaped cluster of oyster mushrooms is quietly working a marvel most people never see. Beneath the visible caps, a network of white mycelium threads is digesting the wood itself — secreting enzymes that break tough cellulose, hemicellulose, lignin, and pectin into simple sugars the fungus can feed on. This is saprophytic life in action, and it is exactly the chemistry we set out to capture. From organically cultivated fruiting bodies, we use nothing but hot water to draw out the mushroom’s natural fungal polysaccharides — including beta-glucan — then spray-dry the liquor into a standardized powder carrying 10% to 30% polysaccharides. The fruiting body it came from is famously nutrient-dense, holding roughly 20-23 grams of protein per 100 grams alongside a wide amino acid profile and abundant minerals. In traditional dietetics it has long been described as warm in nature and sweet in taste. What reaches your formula is a fine brown to light-yellow, food-grade powder — the forest’s quiet chemistry, concentrated into a single clean ingredient for nutraceutical, functional food, cosmetic, and animal nutrition applications.

Product Highlights

10-30%

Standardized Polysaccharide Range

Every batch is measured against a declared total polysaccharide range of 10% to 30% using the phenol-sulfuric acid method with UV-Vis detection. That means a consistent, quantifiable specification for dosage design — batch after batch, from the first drum to the last.

23g

Protein-Dense Fruiting Body

The raw oyster mushroom naturally carries about 20-23 grams of protein per 100 grams, along with a broad spectrum of amino acids and abundant minerals. This nutrient density carries into the extract, supporting its role as a functional nutrient contributor in food and supplement systems.

H2O

Water-Extracted, Solvent-Free

Hot water alone draws out the water-soluble polysaccharide fraction — no organic solvents, no chemical processing aids anywhere in the chain. The result is a genuinely clean ingredient you can explain to customers in one sentence: mushroom plus water.

β-G

Beta-Glucan-Rich Fungal Profile

Beta-glucan and fungal polysaccharides are structural compounds native to the oyster mushroom fruiting body, carried intact through water extraction. These naturally occurring constituents are what give the extract its recognized value in immune-support nutraceutical formulation work.

Function & Wellness Benefits

A

Beta-Glucan for Immune-Support Formulas

The fruiting body’s beta-glucan and fungal polysaccharides are the compounds most sought after by formulators building immune-support products. In capsules, tablets, and compound powders, this extract delivers those naturally occurring constituents in a standardized, quantifiable form — a dependable backbone for nutraceutical product development.

B

Natural Mushroom Flavor & Nutrients

Beyond polysaccharides, the extract carries the mushroom’s characteristic aroma and a functional nutrient profile — protein, amino acids, and minerals. For functional foods, solid beverages, and meal replacement powders, it adds both recognizable mushroom character and compositional depth from a single botanical source.

C

Antioxidant Activity Contributor

Possessing antioxidant activity, this food-grade extract serves as a thoughtful addition to skincare raw-material formulas, where it is incorporated for soothing and antioxidant purposes. For natural cosmetics brands, it brings a forest-origin story alongside measurable functional character.

D

Bioactive Base for Animal Nutrition

As a feed additive raw material, the extract supplies naturally occurring bioactive components for animal health products. Its food-grade quality and traceable organic sourcing make it an attractive functional ingredient for manufacturers serving the growing natural animal nutrition segment.

Frequently Asked Questions

What exactly does “10%-30% polysaccharide” mean when I’m building a formula?
+

It is the declared assay range for total polysaccharides, measured by the phenol-sulfuric acid method with UV-Vis detection against a standard curve. Each production batch is quantified within this window — for instance, one batch may test at 20%, another at 25% — and the precise figure is printed on the batch COA. In practice, this gives your R&D team a dependable, reproducible reference point for dosing, blending, and label documentation.

How is this extract different from plain oyster mushroom powder?
+

Plain mushroom powder is simply dried, milled fruiting body — everything retained, nothing concentrated. This extract takes a different route: hot water selectively concentrates the water-soluble polysaccharide fraction and standardizes it to a 10%-30% assay. You get a higher density of the functional polysaccharide compounds per unit weight, while the broader nutritional background of the mushroom is still carried along. Choose whole powder for maximum fiber and full-spectrum composition; choose the extract when standardized polysaccharide concentration is your priority.

Why water extraction instead of alcohol or organic solvents?
+

Because the target fraction is water-soluble. Hot water selectively dissolves the polysaccharides — including beta-glucan — from the fruiting body while leaving insoluble structural fiber behind. It is the gentlest possible solvent: no organic solvents, no residual-solvent question on your COA, and a story you can tell cleanly. The extract is also water-dispersible in finished formulations, forming a uniform suspension that suits beverages and powders alike.

Can I get samples and organic documentation before a bulk order?
+

Absolutely. We provide complimentary samples for quality evaluation, along with the batch COA, and organic cultivation documentation on request. We encourage you to verify polysaccharide content, run your own compatibility tests, and confirm organic compliance for your specific finished product with your certifying agent — certification of a finished formulation depends on the complete recipe and processing environment, so an early check saves time downstream.
