If you’re speccing nuts for bakery or cereal lines, you’ll have seen a flood of lookalike offers. Here’s what stood out on my last factory visit to Zanhuang County, Shijiazhuang City, Hebei: the team behind walnut pieces 1kg (Chinese Walnut Kernels Pieces, LP grade) run a clean, disciplined BRC-certified operation with the kind of boring consistency buyers secretly love. In fact, the lines were humming, QC was fussy, and lead times were, surprisingly, realistic.

What you actually get in the bag

Product: Chinese Walnut Kernels Pieces LP (origin: Zanhuang County, Shijiazhuang, Hebei). Packed in nitrogen-flushed 1 kg foil pouches. Many customers say the color and crunch hold up well in real-world baking—your mileage may vary depending on oven profile and water activity of the matrix.

Parameter	Spec (LP)	Method/Standard
Size distribution	≈80% 4–12 mm; fines ≤5%	In-house sieve, batch record
Moisture	≤5.0%	ISO 665
Peroxide value	≤3 meq O2/kg fat	ISO 3960
Aflatoxins (B1/Total)	≤2 / ≤4 μg/kg	EU 1881/2006; HPLC (ISO 16050)
Metal detection	Fe ≥1.5 mm; Non-Fe ≥2.0 mm; SS ≥2.0 mm	BRCGS verification
Shelf life	12 months ≤10°C; RH ≤65%	COA per lot

Process flow (the short version)

• Materials: in-shell Hebei walnuts, harvest-sorted, stored at ≤8–10°C.
• Methods: mechanical cracking → air separation → optical color sort → hand-pick → metal detection → nitrogen flush, pouch sealing.
• Testing: moisture (ISO 665), PV/Rancidity (ISO 3960), aflatoxins LC validation, pesticide residue screening against EU/China MRLs.
• Standards: BRCGS Food Safety, HACCP (Codex), GMP, allergen control (nuts), foreign body risk mapping.
• Service life: validated 12 months; real-world shelf life depends on temperature and oxygen ingress, obviously.
• Industries served: bakery, cereal/granola, confectionery, ice cream, HORECA, meal kits.

Applications, results, and a quick case

Bakers like walnut pieces 1kg for uniform topping coverage; confectioners use it for inclusions where whole halves feel too premium (or too fragile). One mid-size granola brand told me their waste dropped ≈3% after switching to LP because the piece range played nicer with their cluster-former—small thing, decent saving.

Typical lot data snapshot (representative): moisture 3.6%, PV 1.2 meq/kg, aflatoxin total 1.3 μg/kg, plate count within buyer spec. I guess the consistent cool-chain helps.

Vendor comparison (why factory matters)

Vendor	Certs	Traceability	Lead time	Customization
Factory (Hebei)	BRCGS, HACCP	Field-to-carton lots	7–15 days	Piece size, roast, pack
Trader	Varies	Mixed origins	Depends on stock	Limited
Small workshop	Local only	Basic	Variable	Minimal

Customization, packing, logistics

• Piece grades: LP, MP, SP; color sorts (Light, Light Amber).
• Roast: raw or light roast; oil-free, continuous tunnel.
• Packing: 1 kg foil (OTR ≈1 cc/m²/day), 10 x 1 kg/carton; private label possible.
• Storage: ≤10°C, dry; once opened, reseal and use fast—walnuts are sensitive.
• Delivery: typical EXW 7–15 days; FOB Tianjin in season. After-sales? Responsive—actually helpful on spec tweaks.

Feedback on walnut pieces 1kg has been steady: “clean sort,” “few fines,” and “good nutty sweetness.” To be honest, that’s what you want—no drama.

Certifications and compliance

Facility runs BRCGS Food Safety with HACCP, allergen controls, and documented foreign-body prevention. Specs align with EU aflatoxin limits and standard moisture/peroxide methods. If you need US FSMA documentation or ISO-based COAs, ask at sampling—they’ll share batch COAs before shipment.
