Specify Black Fungus by Form, Ear Condition and Cleanliness
Black fungus is bought for its recognizable shape and resilient texture. A useful specification separates the intended cut from stem remnants, broken material and non-product matter.
Ear and stem condition
State acceptable ear thickness, stem attachment and hard-base limits for the intended bite.
Breakage and cleanliness
Set measurable limits for fines, damaged pieces, extraneous plant matter and other foreign material.
Application fit
Approve the proposed form in the actual soup, stir-fry, prepared-meal or retail-pack workflow.

Choose the Black Fungus Form That Fits the Process
Pieces retain a natural ear appearance; strips and shreds suit portioned stir-fries and meal kits; dice support controlled dosing. Current working options include 20–50 mm pieces, 5 × 30–50 mm strips, 10 × 10 mm dice and 3–5 × 30–50 mm shreds, subject to final specification and route confirmation.

Confirm Black Fungus Identity and Form for Each Order
We coordinate the declared product identity, China supply route, working form and frozen-stock position for the order. Repeat programs should carry forward an approved shape, stem condition and cleanliness reference rather than rely on the product name alone.
| Decision field | What we confirm | Why it matters |
|---|---|---|
| Identity and form | Declared mushroom identity plus pieces, strips, dice or shreds | Prevents trade-name and cut ambiguity |
| Physical grade | Dimensions, stem attachment, broken pieces and fines | Protects bite, yield and visual consistency |
| Lot acceptance | Foreign material, sensory condition and agreed testing | Creates a measurable release basis |
| Commercial route | Quantity, pack, destination, documents and timing | Lets us match a suitable partner factory route |
Control Cut Size, Stem Attachment and Foreign Material
The signed specification should identify product and form, nominal size, off-size and broken-piece tolerances, stem attachment, color and odor, clumps or surface ice, foreign material, chemistry, microbiology and any destination-market tests.

Use these answers to prepare your product inquiry. The quotation states product availability, specification, packing and delivery timing.
Which frozen black fungus forms can XMG supply?
Working options include pieces, strips, dice and shreds. Current reference dimensions are shown on this page, while exact tolerance and availability are confirmed in the quotation.
How should black fungus size be specified?
State the nominal dimensions, off-size allowance, broken or fine fraction and sampling method. Add a representative sample when natural shape makes a written dimension insufficient.
Can stem attachment and hard bases be controlled?
Yes. Define stem attachment or hard-base limits, the inspection method and the acceptable visual reference in the signed specification.
How are foreign material and damaged pieces handled?
Set measurable limits for extraneous plant matter, other foreign material, damaged pieces and fines, together with the agreed sampling and release basis.
Is the product supplied with glaze?
Do not assume a fixed glaze or surface-ice level. Tell us the application and receiving requirement so the quoted specification can state the relevant condition and test method.
Can XMG coordinate foodservice or private-label packing?
We coordinate net weight, bag or liner, carton, artwork, coding, label language and loading requirements with a suitable packing route.
Which certificates and lot documents are available?
Share the destination and customer approval list. We confirm the certificate holder, facility and product scope plus agreed lot and shipment records before order approval.
What should I send for a black fungus quote?
Send form, size, stem and breakage limits, application, quantity, pack, destination, tests, documents and timing. Include a current specification or benchmark sample when available.
