Our Pleurotus Citrinopileatus Extract is unique because it is a high-quality bioactive ingredient that comes from Golden Oyster mushrooms using cutting-edge water extraction technology. Our extract has a natural ergothioneine content that is standardized at 0.5 to 2%. It gives your high-end formulas great antioxidant power.
We process up to 3,000 tons of botanical materials every year and have been doing so for over 14 years. Our building has 4 big extraction vessels (6 m³ each) and 3 built-in concentration systems that make sure the quality is always the same and the supply is stable. Each batch is certified to meet international standards like ISO 9001, HACCP, Kosher, and Halal. We're your reliable partner when it comes to bringing high-quality mushroom extracts to market. Our customer service is available 24/7, and we deliver in-stock items within 7 days.
People love golden oyster mushrooms because they look beautiful and are full of healthy nutrients. But within 48 hours, fresh mushrooms start to go bad quickly, so extraction is needed to keep bioactive chemicals safe.
Thanks to advanced processing methods, our product solves this problem. We get key chemicals out of chitinous fungal cell walls, which makes them much more bioavailable for your customers.
As a result? A stable, light yellow-brown powder that keeps the natural healing qualities of the mushroom. You can add concentrated ergothioneine, beta-glucans, and phenolic antioxidants to your recipes without having to worry about the limitations of raw materials.
This standard style makes sure that dosing is the same from batch to batch. You can always count on consistent performance, whether you're making supplements or makeup.

1. Natural Mushroom-Sourced Ergothioneine
Our ergothioneine comes straight from Golden Oyster mushrooms, unlike synthetic versions that are sold in stores. This natural source makes sure that clean-label formulas are more biocompatible and consumer-friendly.
2. Powerful Antioxidant & Anti-Aging Properties
Ergothioneine is a very rare amino acid that protects cells very well. It fights free radicals and keeps cells healthy, which makes it perfect for anti-aging skin care and health goods.
3. Safe & Clean Ingredient Profile
Our extract meets all global regulatory standards because it has all the necessary certifications and is subject to strict quality control. You can be sure that every batch meets standards for food safety and cosmetics safety.
4. Perfect for High-End Formulations
Because it is light in colour and has a neutral profile, our Pleurotus Citrinopileatus Extract works well with high-end products. The finished goods will still look good and feel good after using it.
5. Content Options That Can Be Changed
We are aware that different uses call for various amounts. You can tell our OEM/ODM services what levels of ergothioneine and other factors you need for your specific formulation.
Personal Care and Cosmetics
Our extract is a cutting edge part of serums, moisturizers, and eye creams that fight age. Ergothioneine helps skin cells heal naturally and protects them from damage caused by free radicals.
The antioxidants help fight environmental stresses like smog and UV radiation. Your buyers will like how their skin looks and feels after using your products.
Dietary Supplements & Nutraceuticals
People who care about their health look for natural compounds that help their overall health. Beta-glucans and polysaccharides in golden oyster mushroom extract help to regulate the immune system.
By supporting good gut flora, ergothioneine also helps with digestive comfort. Some studies show that it may help with occasional constipation and make it easier for the body to absorb nutrients.
Functional Drinks and Foods
You can put our extract in nutritional powders, health bars, or drinks. The small particle size (80 mesh) makes it easy to mix with different formulation matrices.
Because the extract is hygroscopic, it can expand 10 to 20 times its size when it comes in contact with water. This helps with texture and fullness in functional food uses.

Your supply chain needs a partner who has a track record of producing goods. Our three integrated concentration systems do a great job of vacuum drying, decolorizing, stratifying, and spray drying.
We keep up to 100 tons of stock on hand, so even big orders can be filled quickly. Standard production lead times are 7 to 15 days, but things that are already in stock ship the week after payment.
Our full-chain traceability system links each batch to the materials that went into making it. This openness helps you make sure that your regulatory submissions and quality documentation are correct.
Our dedication to quality is shown by the many foreign certifications we have, such as ISO 22000, GMP, FSSC 22000, and FDA compliance. We welcome plant tours so that you can see for yourself what we can do.

We understand that different order sizes require flexible packaging options:
Our professional export team takes care of all the paperwork for logistics quickly and easily. We offer DDP shipping services to make things as easy as possible for you, but you can choose from other shipping options as well.
Our strong export experience and full integration of the supply chain make international deliveries go smoothly to places all over the world.
