- 01
Assess nameko caps
We review declared nameko identity and incoming mushroom condition with attention to cap integrity and stem condition. The receiving lot is matched to the intended whole, cap-only, half or chopped presentation before sample approval.
- 02
Clean and trim nameko
We confirm cleaning and trimming, with cap diameter and remaining stem length specified for whole mushrooms or caps. Halves need an agreed starting cap size, while chopped nameko requires a particle range and fragment allowance.
- 03
Confirm the frozen presentation
After the agreed preparation and freezing route, we review cap damage, incomplete halves or chopped-piece distribution. Sample checks also cover separation and appearance after the intended cooking process.
- 04
Check nameko release records
We review nameko trimming consistency and cap or cut integrity against the release sample, linking the decision to metal-detection records, pack codes and the required reports before arranging frozen storage and shipment.
Packing and Applications for Nameko
Whole: we discuss whole nameko for cooked soups with recognisable mushroom shapes. Caps: we consider nameko caps for cooked dishes where cap appearance matters. Halves: we discuss halves for cooked preparations requiring visible cut mushroom portions. Chopped: we consider chopped nameko for cooked sauces and blended fillings. Select the packing family, case weight and label for the chosen product form and purchasing channel.

Loading plan: Pallet loading, floor loading or food-grade tote format as stated in the confirmed purchase order.
Keep the Nameko Approval Connected to the Lot
Whole: we review cap integrity and stem condition in the frozen sample. Caps: we review cap damage and trimming consistency against the agreed sample. Halves: we review incomplete halves and breakage in the frozen sample. Chopped: we review cut distribution and unwanted matter in a representative 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.
Which IQF frozen nameko forms can XMG supply?
Working options include whole mushrooms, trimmed caps, halves and chopped pieces. Cap size, stem length, cut and current availability are confirmed in the quotation.
How is nameko cap size specified?
State the target diameter band, off-size allowance and sampling method. Current whole-cap references are commonly built around 10–25 mm, subject to final approval.
Can stem length be controlled?
Yes. Define the maximum stem length, trimming direction and tolerance for detached or broken stems in the signed specification.
Is the natural surface coating a defect?
Nameko can have a characteristic surface condition. Approve the expected frozen and cooked appearance on a representative sample and separately define unwanted clumps or surface ice.
Will whole caps remain intact after cooking?
Result depends on grade and the cooking process. Test the proposed cap grade in the actual soup, sauce or meal and record the acceptable breakage and texture.
Can nameko be packed for foodservice or retail?
We coordinate net weight, bag or liner, carton, artwork, coding, label language and loading requirements with a suitable route.
Which tests and documents can be supplied?
Tell us the destination and approval list. We confirm production facility certificates, product documents, lot COA, agreed tests and shipment records for the order.
What is needed for a nameko quote?
Send form, cap size, stem condition, application, quantity, pack, destination, tests, documents and timing. A current specification or benchmark sample helps shorten review.
