Shiitake Mushroom Extract Powder is a mushroom extract powder derived from selected fruiting bodies of shiitakes with the retention of the naturally occurring polysaccharides and beta-glucans and other characteristic mushroom compounds, which is produced by extracting, filtering, concentrating, and spray-drying shiitake. This fine powder is in high demand by buyers as a result of its consistent quality, versatility in formulation, and suitability for a variety of delivery systems such as capsules, tablets, sachets, solid drinks, nutrition blends, and instant beverage applications, and is widely used in the manufacture of nutraceuticals, functional foods, beverages, and wellness products. Manufacturers will provide an extract ratio and tailor the specifications, depending on the requirements of production, to ensure that different product development projects as well as regional market standards are met. The powder overall is light yellow to brown in colour, with good dispersibility and process adaptability; thus, it can be applied in large-scale blending in industry and OEM/ODM applications. Given the mushroom's potential to be used as a functional ingredient in the international health and nutrition industry, it is still a valuable raw material for enterprises looking for naturally derived botanical and fungal raw materials for extensive commercial applications and reliable manufacturing.

Lentinan Extract is distinguished by its naturally high polysaccharide and beta-glucan content derived from mushrooms and its fine-powder structure, which makes it possible to formulate and process it efficiently in industry. This material is usually light yellow to brown in colour and has a mild characteristic mushroom smell with low moisture content; it has good bulk density, providing better storage stability and transportation efficiency in large-scale manufacturing. Powder's formulation characteristics are also good for dry blending systems for capsules, tablets, nutritional sachets, powdered beverages, seasoning blends, and functional food premixes. It can be formulated to be water-dispersible to suit the extraction technology and the required mesh size, to enable optimisation of the suspension behaviour, solubility and texture properties in various applications. The extract is also rich in naturally occurring polysaccharide fractions, amino acids, and fungal bioactive compounds that will be relatively stable under standard food processing conditions when stored properly. Furthermore, its powder is highly valued in industrial ingredient systems as it can be used in multi-ingredient systems to enrich formulations with mushrooms, while maintaining the overall stability of the products and minimizing the influence on other ingredients in the product formulation.
1. Store in a Cool and Dry Warehouse
It should be stored in a clean, well-ventilated, and low-humidity place after bulk delivery to ensure the stability and processing performance of the powder during long-term storage. Good stability in the surroundings is suggested for industrial stock management.
2. Keep the Original Packaging Properly Sealed
The material is already packaged in our company in accordance with the bulk export specifications and is transported with moistureproof inner packages and reinforced cartons. It is recommended that the customers keep the original seal before production use to avoid unnecessary exposure to air and humidity.
3. Avoid Direct Sunlight and High-Temperature Areas
The product should be kept away from direct sunlight, boilers, heating equipment, or any other heat-generating apparatus. It may be gradually affected by continued exposure to high temperatures, which may alter the physical condition and sensory properties of the powder.
4. Reseal Promptly After Opening
If containers are partially used, the manufacturers should close the containers immediately after each use. Good sealing can help to maintain uniformity of powder flowability and minimize moisture pickup when repeatedly handled.
5. Prevent Contact with Strong Odors or Chemicals
In certain warehouse conditions, mushroom powders may be susceptible to absorbing odors from surrounding volatile chemicals, solvents, and/or strong-smelling raw materials; therefore, it is important not to place Shiitake Extract Powder near such materials.
6. Implement FIFO Inventory Management
While the buyers are encouraged to adhere to the FIFO (First in, First out) warehouse practices for making efficient batch rotation and maintaining stable raw material management throughout the schedule of the production.
7. Maintain Clean Handling Procedures
For secondarily dispensed or transferred product, or product that is transferred during secondary operations, it is recommended that the tools used and the handling conditions be kept clean to minimize the potential for contamination and to ensure consistent product quality in the industry.

Shiitake Mushroom Polysaccharide Powder is processed into a powder profile with a stable microbial balance and is easy to process and incorporate into various mushroom blends and formulations, such as capsule blends, tablet systems, powdered beverage mixes, liquid concentrates, and multi-component nutritional formulations, which is why it is widely used by manufacturers. For capsule formulations, the plant-based extract may also be mixed with flow-enhancing excipients or plant-based carrier materials to facilitate filling consistency, bulk density balance, and production in high-speed capsule filling. In the manufacturing of tablets, the powder is normally pre-blended with granulating aid materials to ensure the uniform distribution of particles in large-batch production, to reduce segregation in the powder mixing, and to improve the compressibility of the powder. The use of controlled mesh sizing and staged dry blending may be used by the manufacturers of instant drink powders and/or sachet systems to enhance the dispersion behavior and facilitate smoother hydration behavior in the finished product. In general, the extract is recommended for use in stabilised suspension systems or water-based concentrates where the use of homogenisation and controlled mixing temperatures can ensure uniformity of formulation and appearance of the product. The extract concentration, carrier ratio, moisture specification, and particle fineness can also be modified as required by the manufacturer to optimise the product for the specific processing equipment, sensory requirements, and regional product standards, depending on the target product format.
