Organic Lentinula edodes Fruiting Body Extract — 30% Polysaccharides
Organic shiitake fruiting body extract standardised to 30% polysaccharides, drawn from certified organic cultivation rather than the conventional log-grown material behind our standard 30% grade. The specification is identical to the conventional SKU; what changes is the input, and therefore the paperwork that has to accompany it.

Buyer Decision Guide
When a buyer specifies organic shiitake, the assay is usually already settled and the real question is whether the certificate chain will satisfy their market. Three points decide it.
- Polysaccharides: 30% by UV, matching the conventional grade so formulas do not need rewriting.
- Organic certificate and lot transaction certificate supplied with the shipment on request.
- Identity confirmed as Lentinula edodes fruiting body, not mycelium or a spent-substrate blend.
- Moisture, ash, heavy metals and microbiology reported per batch.
- Certifying body confirmed per origin lot before the order is accepted.
- COA, specification sheet and safety data sheet accompany each shipment.
How This Grade Differs
The conventional 30% polysaccharide shiitake extract is listed separately. This page is the organic input version at the same assay, so the two are interchangeable in a formula but not in a certification file: only one of them carries an organic certificate chain.
Quality and Documentation
Each lot is assayed by UV for polysaccharides and checked for moisture, ash, heavy metals and microbiology. The organic certificate set for the origin lot is filed with the batch record.
Regulatory Note
Organic grade: the material is sourced from certified organic growers and processors. The organic certificate and the lot transaction certificate are provided with each shipment on request. The certifying body and the standard applied differ by origin lot, so confirm the standard your market requires (for example NUS/NOP-type, EU 2018/848 or China Organic) before ordering. Certification is held by the producing operation and travels with the lot.
Frequently Asked Questions
What do you declare for moisture and ash?
Both are released against the limits on the approved specification; the measured result for your lot appears on its COA.
How recent is the representative batch shown?
The batch referenced is issued per lot; your shipment is released on its own certificate rather than the representative one.
Does the percentage refer to one compound or to a group?
It refers to Polysaccharides 30% by UV, calculated by UV on the basis stated on the COA.
How long can we hold stock before use?
Two years from the manufacture date when the pack stays sealed and dry.
Which test method should our QC lab expect to reproduce?
UV, with the reference standard and calculation basis recorded on the batch certificate.
Can I review the COA before I pay?
Yes. Request the current or representative COA and check identity, method, limits and results before approving the purchase order.
Can you produce to our own specification or packing?
Alternative assay targets, particle size, packing and private-label requirements are reviewed case by case, subject to production feasibility and a revised written specification.
Are you a manufacturer or a trading company?
LongBio is Shaanxi Longsheng Biotechnology Co., Ltd., a direct manufacturer of botanical extracts and functional ingredients integrating R&D, production and export support. Factory review can be arranged by video or an on-site visit.
