Tremella (Tremella fuciformis) Extract Powder for Moisture-Themed Beverages and Powder Blends: Water Behaviour, Formats and Buyer Specification
Tremella fuciformis sporocarp extract powder (40:1) is soluble in water and suits beverage, soup and dry powder blend formulations. This guide covers its glucuronoxylomannan polysaccharide character, its water-holding behaviour, the formats it suits and the specification a buyer should set before ordering.

What is Tremella extract powder?
Tremella fuciformis, known as white fungus or snow fungus, is an edible fungus. The catalogue extract is a sporocarp extract supplied as a powder at a 40:1 extract ratio. The product page describes the whole fungus as white to pale yellow in colour, with a soft, gel-like texture.
For a broader product overview, see the White Fungus (Tremella fuciformis) Extract Powder product page.
Polysaccharide character and marker
Tremella polysaccharides are generally described as glucuronoxylomannan, a heteropolysaccharide that contains glucuronic acid residues. The catalogue specification uses glucuronic acid as the standardisation marker, at 10–25%. A marker range describes one measured constituent. It is not a complete structure of the polysaccharide fraction, so the lot assay on the certificate of analysis is the figure to check.
Water-holding and soft jelly behaviour
The product page describes the powder as water-holding. The specification records it as soluble in water, so dispersion should be tested in each finished matrix. The measured water-holding value for a lot is confirmed on the certificate of analysis issued for each lot. Whether the powder forms a stable gel at a given use level is agreed with our technical team for the intended use level. The soft, gel-like texture described above refers to the whole fungus, not to the extract in a finished product.
Formats that suit the material
- Beverages and drink powders, where water solubility governs dispersion.
- Soups and savoury powder blends.
- Dry powder blends for reconstitution in water-based systems.
- Soft jelly, a Bionutricia format for moisture-themed products. A gel or soft jelly format needs a trial at the intended use level; the tested use level and gel strength are agreed with our technical team for the intended use level.
Human research position
The human Tremella randomised trial (PMID 29319408, Journal of Medical Food, 2018) measured cognitive outcomes, not skin outcomes, and is not cited here as skin evidence.
Human evidence of a skin-moistening benefit for Tremella fuciformis as a single ingredient is not established (Archives of Dermatological Research, 2023; PMID 36757441).
What a buyer must specify
Set these items in the purchase specification before ordering:
- Species, part and extract ratio: Tremella fuciformis, sporocarp, 40:1.
- Marker and assay method: glucuronic acid, 10–25%, with the method stated.
- Particle size (mesh): confirmed on the certificate of analysis issued for each lot.
- Moisture content: confirmed on the certificate of analysis issued for each lot.
- Microbial limits: confirmed on the certificate of analysis issued for each lot.
- A certificate of analysis for every lot.
Specification table
| Parameter | Catalogue figure | Buyer action |
|---|---|---|
| Botanical identity and part | Tremella fuciformis, sporocarp | Confirm species and part against each lot’s documents. |
| Form | Powder | Specify particle size (mesh): confirmed on the certificate of analysis issued for each lot. The product page notes that texture may vary and some powder is coarser. |
| Extract ratio | 40:1 | Record alongside the marker assay. |
| Marker | Glucuronic acid, 10–25% | Check the lot assay on its certificate of analysis. |
| Solubility | Soluble in water | Test dispersion in each finished matrix. |
| Moisture content | Confirmed on the certificate of analysis issued for each lot | Set an acceptance limit in the purchase specification. |
| Microbial limits | Confirmed on the certificate of analysis issued for each lot | Set limits in the purchase specification and check each lot’s certificate of analysis. |
| Handling and shelf life | 24 months in original sealed packaging, below 25°C and relative humidity below 65% | The powder may clump with heat or moisture, so store it accordingly. |

Frequently asked questions
Which marker is used to standardise the extract? Glucuronic acid, stated in the specification at 10–25%. The certificate of analysis for each lot gives the measured value for that lot.
Is the extract soluble in water? Yes, the specification records water solubility. Dispersion and sensory performance should be tested in the finished matrix.
What should a buyer specify when ordering? Species and part, the 40:1 extract ratio, the glucuronic acid marker and its assay method, particle size, moisture content, microbial limits, and a certificate of analysis for every lot. The figures are set out in the specification table in the body.
How is the material ordered? Enquire through the contact route for bulk supply, a certificate of analysis for each lot, documentation and packing options.
