What Makes Our Powder Different
1. Freeze-Drying vs. Hot-Air Drying
Heat drying at normal temperatures (60–80°C) breaks down heat-sensitive polysaccharides. The steps we take to freeze-dry:
- During the melting process, it works at -40°C.
- Keeps 92–96% of the original carbohydrate content
- Keeps the natural smell ingredients of mushrooms
- Makes an open structure that lets it soak up water right away.
Lab Comparison: Samples that were freeze-dried keep 3.2 times more polysaccharides than samples that were hot-air dried (internal testing data is provided upon request).
2. Polysaccharide Standardization
HPLC tests are done on each batch to make sure:
- 10% spec: Cost-effective for use in cooking
- 20% spec: Drinks with a good balance of nutrition and flavour
- 30% spec: Supplemental formula that is concentrated
Every package of Boletus Mushroom Powder comes with a Certificate of Analysis (COA).
3. Clean Label Formulation
- No man-made ingredients
- There are no fillers or flow aids.
- Product made from only one material (100% Boletus edulis)
- Fits boasts of being vegan, vegetarian, or paleo

Application Guidelines
For Dietary Supplement Manufacturers
Recommended Dosage: 500-1500mg per serving
- Capsules/Tablets: Blend with microcrystalline cellulose (typical ratio 1:1)
- Powder Blends: Mix with carrier powders; ensure moisture barrier packaging
- Functionality: Immune support formulations, mushroom complex blends
For Beverage Developers
Solubility Profile: Disperses in cold water (25°C) within 30 seconds with mild agitation
- Coffee Alternatives: 2-3g per 250ml serving
- Functional Drinks: 1-2g per bottle (adjust for flavor intensity)
- Protein Shakes: 0.5-1g as umami enhancer
Stability: Maintains solubility after 12-month storage when kept dry.
For Food Manufacturers
Usage Rate: 0.5-2% of total formulation
- Soup Bases: Replace 10-15% of MSG for natural umami
- Seasoning Blends: Combine with sea salt, herbs
- Savory Snacks: Dust coating or dough incorporation
Heat Stability: Withstands cooking temperatures up to 120°C for 30 minutes without significant polysaccharide loss.

Manufacturing Process
Step-by-Step Production
Stage 1: Raw Material Verification
- Get your boletus from licensed growers in Yunnan and Sichuan states.
- Visual inspection and moisture testing for incoming QC
- <2% rejection rate (normal for the industry: 8–10%)
Stage 2: Pre-Treatment
- Sorting by hand to get rid of broken specimens
- Ultrasonic cleaning gets rid of 99.5% of dirt and grime.
- Slices that are all the same thickness (3-5 mm) to dry quickly.
Stage 3: Freeze-Drying Cycle
- -45°C for 4 hours (ice crystal creation) to freeze.
- Drying at -40°C, 50 mTorr hoover, for 20 hours - initial drying
- Secondary Drying: -10°C, 10 mTorr, 6 hours (to get rid of any remaining wetness)
- The end moisture level was less than 6%.
Stage 4: Milling & Standardization
- Cryogenic grinding (which stops heat production) 80–120 mesh screening
- Tests for polysaccharides (HPLC method according to USP norms)
- Blending to meet the goal standard (within 2% of that)
Stage 5: Quality Release
- Microbiology tests: E. coli, Salmonella, TPC, yeast/mold, and yeast/mold
- ICP-MS study of heavy metals
- Screen for pesticides: GC-MS/LC-MS (if organic claims are made)
- Batch release only after all rules have been met
Stage 6: Packaging & Storage
- Flushing with nitrogen before closing (lowers oxidation)
- PE bags coated with aluminium foil and a fibre drum
- Conditions in the warehouse: 18–22°C, 40–50% RH
Packaging & Logistics
Standard Packaging
- Bulk: 25kg/fiber drum (ID: 38cm × H: 50cm)
- Inner: Double PE bags (food-grade, heat-sealed)
- Outer: UN-certified fiber drum + pallet option
Custom Packaging Available
- Retail pouches: 50g / 100g / 500g stand-up bags
- Wholesale: 5kg/aluminum foil bag
- Private labeling: Full artwork support

A: Yes. We provide free 50-100g samples (shipping extra). Lead time for samples is 3-5 days.
Q: Differences between 10%, 20%, and 30% polysaccharide grades?
A: Higher concentrations have more beneficial chemicals per gram but harsher mushroom flavour. Choose by application:
- 10%: Seasonings for delicate flavour in cooking
- 20%: Functional beverage balance
- 30%: High-potency supplements in fewer servings
Q: Is it heavy metal and pesticide-tested?
A: Each batch is tested for 4 heavy metals (Pb, As, Cd, Hg) and 500+ pesticide residues. COA includes results.
Q: Can you match a competitor's specs?
A: Submit their COA or specification document. Analysing it will determine if we can reproduce or enhance it.
Q: Do you certify organically?
A: The facility is organic-certified. Raw material harvest season determines organic boletus powder availability. Contact us for organic inventory.
