Explore our highly standardized raw materials engineered for nutraceutical, pharmaceutical, and functional food applications.
Understanding the scientific shift toward mushroom-derived immunomodulators and bioactive polysaccharides.
In the rapidly evolving landscape of functional ingredients, Agaricus subrufescens (commonly known as Agaricus blazei Murrill, Cogumelo do Sol, or the Royal Sun Agaricus) has emerged as a cornerstone of modern immunology and cellular health. Unlike traditional botanical ingredients, Agaricus extract contains an exceptionally high concentration of Beta-1,3-D-glucan and Beta-1,6-D-glucan complexes. These unique proteoglycans interact directly with human immune receptors, offering unparalleled support for cellular defense, metabolic regulation, and systemic vitality.
As global consumer demand shifts toward clean-label, scientifically validated, and organic ingredients, wholesale buyers and product formulators require reliable manufacturing partners. A premium Agaricus extract is not merely a powder; it is a highly engineered bioactive matrix. Achieving this requires precise cultivation controls, advanced hot-water and enzymatic extraction technologies, and rigorous standardization protocols to ensure consistent therapeutic efficacy across every production batch.
Agaricus polysaccharides stimulate macrophage activity, natural killer (NK) cells, and T-lymphocytes, enhancing the body's natural defense mechanisms without over-activating the immune system.
Clinical studies suggest that active compounds within Agaricus subrufescens assist in maintaining healthy blood glucose levels, supporting lipid metabolism, and promoting hepatoprotective pathways.
Rich in polyphenols and superoxide dismutase (SOD) mimics, Agaricus extract neutralizes free radicals, mitigating oxidative stress at the cellular level and supporting healthy aging.
A legacy of scientific excellence, quality assurance, and global supply chain reliability.
Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB), is the China Leading manufacturer and exporter of herbal extracts and its derivatives for more than 20 years. TRB is a technology-based company that combines research and development, production and international market sales.
TRB's rapid development and dedicated service in the plant extract industry over the years has earned us prestigious recognition, including the 2026 "Global Biotechnology and Life Sciences Award" - ''Best Global Herbal Extract Provider 2026''.
Our product portfolio spans high-quality Herbal extracts, Sweeteners, Nootropics, Vegetable & Fruit Juice powder, Essential oils, and Bee Products. We are committed to the research and development of pure natural plant extracts, dedicated to the health of all humanity.
TRB currently operates three specialized factories: one dedicated to herbal extracts, one for bee products, and another for animal extract products. Our facilities are fully certified under global quality systems, including GMP, ISO, HACCP, ORGANIC, FDA, HALAL, and KOSHER Certificates.
In recent years, TRB has focused heavily on the research and development of Nootropics products, such as Brain Health Herb Extract, Anti-Aging Herb Extract, and Longevity Herb Extract, which have received exceptional feedback from our global clientele.
With products exported to more than 60 countries and regions, TRB has established a solid reputation for purity, safety, and supply chain integrity.
How we process raw Agaricus subrufescens into high-potency, bioavailable active powders.
The therapeutic efficacy of Agaricus extract depends entirely on the integrity of its macromolecular structure. Simple crushing or low-temperature milling cannot break down the tough chitinous cell walls of the mushroom, leaving the vital beta-glucans locked inside. At TRB, we employ a multi-stage, scientifically optimized extraction process that guarantees maximum yield and bioavailability.
We source our Agaricus mushrooms from certified organic cultivation bases. The growth substrate, temperature, humidity, and air quality are strictly monitored to prevent heavy metal accumulation and pesticide contamination from the outset.
To extract both water-soluble polysaccharides and protein-bound beta-glucans, we use a pressurized hot water extraction process combined with targeted enzymatic hydrolysis. This breaks down the chitin matrix without degrading the delicate polysaccharide chains.
The crude liquid extract undergoes ultrafiltration to remove low-molecular-weight impurities and concentrate the active macromolecules. This step is crucial for achieving standardization levels of up to 50% polysaccharides.
The concentrated extract is spray-dried in a GMP-compliant Class 100,000 cleanroom. This produces a highly soluble, free-flowing powder with excellent stability, ready for encapsulation, tableting, or functional beverage formulation.
Addressing the critical requirements of corporate buyers, quality assurance managers, and global brands.
We provide comprehensive documentation packages for every batch, including Certificate of Analysis (COA), Heavy Metal Testing (ICP-MS), Pesticide Residue Screenings, GMO-Free Declarations, and Allergen Statements to ensure seamless customs clearance and regulatory compliance in the US, EU, and Asia.
Whether your formulation requires a specific ratio of Beta-Glucans (e.g., 20%, 30%, or 40%) or a highly water-soluble powder for functional beverages, our R&D team can customize the extraction parameters to meet your exact product specifications.
With three dedicated factories and a robust raw material sourcing network, we mitigate supply chain risks. We offer flexible shipping options (Air, Sea, Express) and maintain safety stock levels for long-term contract customers to guarantee uninterrupted production schedules.
How TRB is driving innovation in mushroom biotechnology and active compound isolation.
As the nutraceutical industry moves toward personalized nutrition and targeted therapeutics, the demand for highly specific molecular weights of polysaccharides is increasing. TRB is at the forefront of this evolution, investing in research to isolate specific beta-glucan fractions that target distinct cellular receptors.
Our technical roadmap for the next three years focuses on three primary pillars:
Expert answers to common technical, quality, and procurement inquiries regarding wholesale Agaricus extract.
We offer standardized Agaricus subrufescens extracts containing 30%, 40%, and 50% Polysaccharides as measured by UV-Vis spectroscopy. We also standardize for Beta-Glucan content (typically 20% to 30% using the Megazyme enzymatic assay method) to ensure high bioactivity.
Heavy metal accumulation is a common issue with mushrooms. TRB mitigates this by using strictly controlled organic growth substrates. Every batch of raw material and finished extract is tested via Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to ensure compliance with stringent US FDA and EU regulatory limits for Lead, Arsenic, Cadmium, and Mercury.
Yes, our hot-water extracted powders are highly soluble in water, making them ideal for functional beverages, instant tea blends, and liquid supplements. For solid dosage forms like capsules and tablets, we also offer grades optimized for compressibility and flowability.
Our factories operate under strict GMP guidelines and hold ISO 9001, ISO 22000 (HACCP), USDA Organic, EU Organic, FDA registration, Halal, and Kosher certifications, allowing our ingredients to be used in products worldwide.
Our standard MOQ for wholesale orders is 25kg (one standard fiber drum). For custom formulations or specialized specifications, the MOQ may vary. Lead times typically range from 7 to 15 days depending on the order volume and destination country.
High-purity active ingredients manufactured under strict GMP standards to support global health formulations.
