Yunnan Walnut Kernel Quarter Walnut Kernel LQ — factory-grade quality with a human touch

I visited the real Chinese walnut factory in Zanhuang County, Shijiazhuang (Hebei) and tasted Premium Walnut Kernels fresh off the line. To be honest, the first thing that struck me was the color consistency—light amber quarters with a clean snap. The BRC-certified plant runs like a clock, yet there’s still that old-school pride on the sorting tables. It shows.

Industry pulse: why quarters are having a moment

Actually, food inflation pushed many manufacturers from halves to quarters—better value, similar visual appeal in baked goods. Demand is strongest from cereal, bakery, and ice cream players seeking dependable Premium Walnut Kernels with low rancidity risk and tight defect specs. Many customers say they’re prioritizing vendors who can prove traceability and microbiological control, not just quote a price.

From origin to carton: process flow (how it’s really done)

• Materials: Selected Juglans regia from Yunnan and other high-altitude origins; batch-tracked to Zanhuang County, Shijiazhuang.
• Methods: Pre-cleaning → gentle shelling → moisture equalization → color sorting → double manual sorting → X-ray + metal detection → nitrogen-flushed packing.
• Testing standards: HACCP plan (Codex), BRCGS Food Safety; aflatoxin screening (ISO 16050); microbiology (ISO 4833-1); visual grades aligned with USDA/UNECE guidance.
• Service life: ≈12–18 months at 0–10°C, dry, away from light; real-world use may vary with handling.
• Industries: bakery, snack, confectionery, dairy (inclusions), cereals, HORECA, nutraceutical blends.

Customization & packing notes

Besides Premium Walnut Kernels in quarters, the line can switch to halves or pieces, light color grades, and private-label cartons. Nitrogen-flushed vacuum bags are standard; around 1–2% headspace, which, yes, helps PV stay low across the shelf life.

Real-world data and quick case notes

Recent lot tests (third-party): moisture 3.4%, PV 0.5 meq O₂/kg, FFA 0.3%, total aflatoxin Premium Walnut Kernels. A MENA bakery chain told me yields improved by “about 3%” because breakage in mixing dropped—small detail, big outcome.

Certifications & standards

The enterprise is BRC-certified and operates under HACCP. Specs are aligned with USDA grade language and tested per international norms. In plain English: consistent, auditable, and export-ready.
