Key Bioactive Components
Shiitake extract powder is special compared to other mushroom products because it has several helpful substances in it.One important part is Lentinan, which is a type of beta-glucan and has strong effects on the body.It's the main active part of the powder.
Another good substance in shiitake mushrooms is eritadenine, which is a kind of alkaloid.It helps make the extract more nutritious.The powder also has different secondary metabolites, important amino acids like leucine and lysine, and natural ergosterol.
Ergosterol is something that can turn into vitamin D2.Because it has so many plant-based chemicals, it works well for making advanced health products that support the immune system and overall well-being.
Manufacturing Excellence
Our method uses two extraction steps to get the most active compounds by collecting both the alcohol-soluble triterpenes and the water-soluble polysaccharides. The powder's complete range of advantageous chemicals is preserved thanks to this intricate process.
Fine particles with superior dispersibility are produced using sophisticated spray-drying techniques. The extract is ideal for a variety of production procedures, such as pasteurization and encapsulation, because the controlled processing preserves thermal stability up to 120°C.
Strict quality control procedures keep an eye on each stage of production. From the selection of raw materials to the testing of the finished product, our analytical tools confirm the purity, potency, and lack of impurities. To satisfy USP and EP botanical extract requirements, every batch is put through extensive testing.
Application Versatility
The rich umami taste and mild, savory flavor work well with drinks, supplements, and healthy foods.Its high water solubility allows it to mix easily into liquids without separating or settling.
When making tablets, compressing powder, or mixing with other ingredients, its small size and proper bulk density (0.45-0.65 g/ml) help it flow smoothly through equipment.
If stored properly, it doesn’t absorb much moisture, so it stays dry and doesn’t clump, keeping the product quality strong during manufacturing.Since the extract can handle heat, it’s useful in products that are cooked or heated.This makes it flexible for use in many types of products and helps keep the active ingredients effective.
Quality Assurance & Certifications
Xi'an Linnas Biotech keeps up-to-date, ISO 9001-certified quality management systems. Our Shiitake Extract Powder satisfies Kosher, Halal, and HACCP food safety regulations.
Testing involves checking for beta-glucan using the Megazyme method and measuring polysaccharides with UV-VIS spectroscopy.This helps tell real beta-glucans apart from starch fillers, making sure the product is genuine.
To keep the product safe and pure, we test for microbes, check for heavy metals, and look for pesticide leftovers.For customers in other countries who need official papers, we also offer lab tests done by a third party to make sure the quality is top-notch.
Packaging & Storage
Aluminum foil bags are typically used for packing products weighing one to ten kilos.Fiber drums are the typical choice for orders weighing 20 to 25 kg.The product is better protected from light, moisture, and air when it is packaged in numerous layers.
The product should be kept out of direct sunlight and in a cool, dry location to preserve its freshness for up to 24 months. Maintaining the proper amounts of active chemicals and keeping the product from absorbing moisture are two benefits of proper storage.

Frequently Asked Questions
Q: What ratio of extraction should I use in my formulation?
A: Your intended dosage and application will determine the ratio. While 30:1 or 50:1 ratios offer greater potency for capsule formulations requiring smaller dose sizes, a 10:1 extract delivers a moderate concentration appropriate for drinks.
Q: How can the polysaccharide content be guaranteed to be constant?
A: We employ Megazyme Beta-glucan testing, UV-VIS spectroscopy, and standardized dual-extraction techniques. Before being released, every batch is checked to ensure it falls within the designated polysaccharide range.
Q: Is this extract resistant to processing at high temperatures?
A: Our powder is suitable with the majority of manufacturing procedures because it retains bioactivity up to 120°C during pasteurization and typical encapsulation temperatures.
Q: Do you offer samples for examination?
A: Definitely. Before placing larger orders, we provide 20g samples so you may assess quality, solubility, and compatibility with your formulation.
Q: What paperwork do you offer for shipping internationally?
A: To speed up customs clearance across the globe, we provide comprehensive documents such as Certificate of Analysis, manufacturing certificates (ISO, HACCP, Halal, Kosher), phytosanitary certificates, and commercial invoices.
