CHINA-BASED B2B SUPPLY
IQF Frozen Boletus and Porcini for Specified Cuts and Grades
We supply IQF frozen boletus and porcini in whole pieces, slices, dice and quarters for sauces, soups, pasta, prepared meals and foodservice. Because trade names can cover different material, we first confirm the accepted species or commercial identity, then align cap and stem grade, cut, defects, packing and documents.
For a useful quotation: send the form or grade, application, quantity, pack, destination, document needs and timing.

Buy Boletus by Declared Identity, Cut and Cap-Stem Grade
“Boletus” and “porcini” are not complete purchase specifications. The order should state the accepted identity and the cap, stem and cut condition that matter in the finished dish.
Cap and stem grade
Define cap diameter, stem length, trimming, worm damage, discoloration and broken-piece tolerances.
Cut geometry
Choose whole pieces, slices, dice or quarters and set thickness or nominal dimensions.
Sensory use
Approve aroma, color, bite and cook performance in the intended sauce, soup or prepared meal.

Choose the Boletus Form That Fits the Process
Choose the form and declared size for your application. Each option below explains its use, specification focus, inspection points and purchasing context. We agree the final requirements against your sample and intended preparation.

no unit more than 20.0% below the lower limit or above the upper limit.
Confirm Boletus Identity and Grade Before Quotation
We verify the declared trade or species identity, China supply route, form and frozen-stock position for the order. We do not treat origin, wild or cultivated status, season or species wording as interchangeable claims.
| Decision field | What we confirm | Why it matters |
|---|---|---|
| Product identity | Accepted trade name, species direction and document basis | Reduces substitution and label risk |
| Physical grade | Cap diameter, stem length, cut and broken tolerance | Controls presentation, yield and dosing |
| Condition | Color, aroma, trimming, defects and foreign material | Protects the finished flavor and appearance |
| Supply program | Quantity, pack, destination, timing and repeat calls | Supports route and stock matching |
Release Boletus on Identity, Cap-Stem Condition and Cut
Use the specification tables for boletus alongside the selected form. Dimensions and defect descriptions apply to the relevant cut, piece or portion. We agree the sampling basis and final order requirements for the intended application.

Processing and Lot Checks for Boletus
We coordinate boletus identification, trimming and cut preparation with separate checks for cap appearance and discolouration.
EQUIPMENT REFERENCE
Conveyor and enclosed equipment
An inclined conveyor stands beside enclosed equipment inside the processing area.
We confirm boletus species, stem trimming and the breakage or cut variation accepted for the selected form.Explore the processing-flow library →
Conveyor at a chamber entrance
A roller conveyor leads towards an opening in a panelled processing enclosure.
Connected conveyor sections
Connected conveyor sections run beside stainless-steel covers, controls and pipework.

Covered stainless-steel line
A long covered line extends across the processing hall beneath overhead pipework.
- 01
Verify boletus identity
We review the declared boletus species and incoming mushroom condition before matching the lot to the order. Damage and discolouration are assessed alongside cap appearance, with the sample reference retained for whole pieces or cuts.
- 02
Clean, trim and cut
We confirm cleaning and stem trimming, then agree whole-piece size, slice thickness, dice dimensions or quarter appearance. Natural cap and stem variation needs clear acceptance criteria rather than a shared size description across every boletus form.
- 03
Review the frozen cut
The boletus order specifies the freezing route and whether blanching or other preparation applies. The frozen sample is reviewed for separation, discolouration and the selected form's breakage, with cooking performance compared to the agreed application reference.
- 04
Release identified boletus packs
We align metal-detection verification, labelled packing and boletus release samples with the purchase order. Species identity and cut consistency are reviewed with the agreed lot reports before we coordinate frozen storage, loading and shipment documentation.
Packing and Applications for Boletus
Whole Pieces: we consider whole pieces for cooked dishes with visible mushroom portions. Slices: we discuss slices for cooked sauces and dishes with visible mushroom profiles. Diced: we consider diced boletus for cooked fillings and mushroom sauces. Quarters: we discuss quarters for cooked dishes needing larger identifiable mushroom pieces. Select the packing family, case weight and label for the chosen product form and purchasing channel.

Pack construction: Food-grade PE liner and export carton; plain bag, adhesive label or printed bag; barcode and customized carton marks.
Loading plan: Pallet loading, floor loading or food-grade tote format as stated in the confirmed purchase order.
Keep the Boletus Approval Connected to the Lot
Whole Pieces: we review species identity, damage and discolouration against the agreed sample. Slices: we review slice breakage and discolouration in the representative frozen sample. Diced: we review cut consistency, fragments and species identity in the sample. Quarters: we review broken quarters and discolouration against the approved sample. Common food-safety checks remain part of the agreed inspection plan; form-specific physical and cooking checks follow the selected sample.

Use these answers to prepare your product inquiry. The quotation states product availability, specification, packing and delivery timing.
Is frozen boletus the same as frozen porcini?
The terms can overlap in trade but should not be assumed to identify the same material. State the accepted species or commercial identity and required supporting documents for the order.
Which IQF boletus forms can XMG supply?
Working options include whole pieces, 5–8 mm slices, 10 mm dice and 20–40 mm quarters. The quotation lists dimensions, grade and availability.
How are cap and stem grades defined?
State cap diameter, stem length, trimming, cap-to-stem balance, broken pieces and visual defects. Use an approved sample where appearance is commercially important.
Can worm damage and discoloration be limited?
Yes. Put measurable limits, definitions and the sampling method into the signed specification and inspection plan.
Is the boletus wild or cultivated, and what is its origin?
We confirm wild or cultivated direction, origin and production window only for the order and supporting evidence. The quotation states the origin and production details for the ordered product.
Can I approve the product in my sauce or soup?
Yes. Application testing is useful for aroma, color, bite, piece recovery and flavor release. Share the recipe conditions and acceptance result with the commercial team.
What documents can be reviewed before an order?
We coordinate product identity information, specification, sample record, production facility certificates, lot COA, agreed tests and shipment records.
What is needed for a useful boletus quote?
Send accepted identity, form, grade, application, quantity, pack, destination, tests, documents and timing. Include current label wording or a benchmark sample when relevant.
