Introduction
Shiitake Extract Powder is a high-concentration functional ingredient derived from Lentinula edodes fruiting bodies, a well-known edible and medicinal fungus. Our product adheres to strict industry standards and advanced technologies, ensuring high purity, stable quality, and maximum retention of natural bioactive compounds.
Raw Material Source
Raw materials are selected from premium, pollution-free Lentinula edodes cultivated in Zhejiang, Fujian (China) and high-quality Japanese production areas. Standardized cultivation and strict pre-inspection (species identification, heavy metal and microbial detection) ensure zero pollution and stable active ingredient content.
Extraction Process
We adopt advanced hot-water extraction, low-temperature vacuum drying and membrane separation purification. The whole process complies with GMP standards, with low-temperature control (<60℃) to avoid heat-sensitive component degradation, ensuring no solvent residues or additives in the final product.
Active Ingredient Content
Standardized and customizable specifications: Lentinan (β-1,3/1,6-glucan) ≥10%-50% (HPLC/GPC), Total Polysaccharides ≥20%-60% (UV), Eritadenine ≥0.2%-2.0% (HPLC, optional). Concentration ratio is 10:1, 20:1 or customized.
Differentiation Advantages
-
High Purity & Activity: Membrane separation removes impurities; low-temperature drying retains lentinan’s bioactivity.
-
Stable Quality: Full-link quality control with available third-party testing reports.
-
Good Solubility: Fine powder (95% through 80 mesh), soluble in hot water without precipitation.
-
Multi-Certification: Complies with FDA, EU Organic, USDA NOP, HALAL, KOSHER for global market.
-
Cost-Effective: High concentration reduces dosage and cost, with better bioavailability than fresh shiitake.
Key Active Compounds
Shiitake Extract Powder’s bioactivity comes from multiple natural active compounds with clear pharmacological effects:
Lentinan (CAS: 37339-90-5)
A β-1,3/1,6-glucan with a triple-helix structure, soluble in hot water. It triggers immune activation, has powerful immunomodulatory effects, and is an approved oncology adjuvant drug in Japan since 1985.
Eritadenine (CAS: 58-61-7)
A water-soluble purine compound unique to shiitake, inhibiting SAHH to reduce plasma total and LDL cholesterol by 25%-45% in high-cholesterol diet animal studies.
Total Polysaccharides
A mixture of water-soluble polysaccharides (including lentinan) that synergistically enhance immunity, scavenge free radicals, and protect cells from oxidative damage.
Other Active Compounds
Including total triterpenes (anti-inflammatory, antioxidant), ergosterol (provitamin D₂), adenosine, amino acids and trace elements, enhancing nutritional and functional value.
Benefits
Immune Regulation
Lentinan stimulates immune cells and cytokine secretion, enhancing innate and adaptive immunity, suitable for people with low immunity, the elderly and post-illness recovery.
Cholesterol Regulation & Cardiovascular Health
Eritadenine and natural statins supports healthy metabolism, lowering serum cholesterol and reducing vascular wellness risk.
Antioxidant & skin wellness support
Total polysaccharides and triterpenes scavenge free radicals, reduce oxidative damage, delay aging and improve skin health.
Intestinal Health Support
β-glucans act as prebiotics, regulating intestinal flora balance and improving digestion and absorption.
Lentinan enhances the immune system’s ability to eliminate cells, widely used as an oncology adjuvant to improve patient survival and quality of life.
Nutritional Supplement
Rich in high-quality protein, B vitamins, provitamin D₂ and trace elements, suitable for daily nutritional supplementation.
