Hefei Fushan Yuansheng Biotechnology Co., Ltd. produces standardised mushroom constituents, including Pure Maitake Extract from the fruiting body of Grifola frondosa cultivated in China. It is supplied as a yellow-brown powder and contains 10–50% polysaccharides and 10–30% beta-glucans in the fully water-soluble grade or 10–50% in the partially water-soluble grade. Test method: UV Shelf life: 24 months It is intended for use with capsules, solid beverages and oral liquids made by nutraceutical, functional food and dietary supplement firms. We can discuss custom content levels as required.

Maitake extract is derived from the fruiting body of the mushroom Grifola frondosa, often known as Hen of the Woods. Hot water and/or ethanol extraction is used to extract the active chemicals such as Beta-1,3/1,6-D-glucans and the protein-bound complexes, D-fraction and MD-fraction.
Raw mushroom powder has indigestible chitin and the nutritional content can vary. The idea of extraction is to have a more concentrated, standardised constituent, which means less material is needed in a capsule or drink.

Other parameters, such as detailed heavy metal limits, MOQ, packaging size and lead time, are not provided on this page. Please ask if you need them.
The powder is hygroscopique. The usual particle size and bulk density shown in the table can be compared with your blending or encapsulating equipment.
The extract is said to be water-soluble, which is ideal for liquid media. Solubility varies with the grade and the formula therefore it is worth checking in your own system.
Beta-glucan profiles can be examined with Megazyme or HPLC enzyme techniques.

FuYNature says its concept is farm plus factory, with controls from strain selection to cultivation for edible and medicinal fungi. The organic products are said to meet EU and US organic export standards for fruiting body powder and extracts.
Extraction is done with hot water . Then ethanol precipitation is done for improved purity . No residual solvents data are available on this page.
Common concerns with mushroom extracts include starch additives or mycelium produced on grain. The Iodine-Starch test and Megazyme Beta-Glucan testing can confirm the polysaccharides are from the mushroom itself.
FuYNature’s ancillary facilities are said to be GMP, ISO22000, HACCP and HALAL certified. Raw materials are defined as per China New Food Raw Materials rules, US FDA GRAS criteria and USP standards. When you enquire, please tell me which documents you need.

FuYNature can supply you formulation and dosage form reference recommendation. Custom final product development requires a separate communication. FuYNature additionally mentions scientific evidence support, patent licensing and regulatory compliance aid as wider services and the scope needs to be determined for each project.

Store powder in a cool, dry area away from light and excessive temperature. Store in original airtight container to avoid caking.
You can use it for 24 months. Please ask for current options as packaging sizes are not displayed on this page.
Q1: What dosage forms can this raw material be used for?
A: Maitake oral liquids, pills & solid drinks. It is also good for functional tea, coffee and liquid vitamins.
Q2: Does this raw material reinforce other tiers of content?
A: Yes Custom parameters are offered at varying levels of content. Please let me know what specs you want.
Q3: Do you approve of the use of formulas and dosage forms?
A: We propose formulations and dosage form references. Separate communication on custom finished product formulation development.
Q4: What is the difference between the product and raw Maitake powder?
A: Raw powder has indigestible chitin. The extraction stage serves to concentrate the active polysaccharides. There is no quantitative bioavailability comparison on this page.
Q5: Is it water soluble and how do I verify authenticity?
A: Solubility is dependent on the grade. The extract is reported to be readily soluble in water. The Iodine-Starch test and Megazyme Beta-Glucan testing can be used to ensure the polysaccharides are from the mushroom and not a grain substrate.
Q6: Shelf life and storage conditions?
A: Shelf-life: 24 months. Store powder cool, dry and sealed, away from light and heat.
