Why Premium Walnut Kernels?
Premium walnut kernels distinguish themselves via strict raw material selection, advanced processing (vacuum/controlled air-dried), and rigorous food safety management (ISO/FDA-compliant). This results in kernels with:
- Lower moisture (enhanced shelf life and crunchiness)
- Aflatoxin control for health and export compliance
- Optimal size, color & minimum shell fragments
- Traceable production—required for top recipe/retail brands

7. FAQ: Expert Guide on Premium Walnut Kernels Technical Terms (7 FAQ)
- 1. What is the “Light Quarters” grade in premium walnut kernels?
- Light Quarters means kernels are split into quarters with a bright (extra light to light) color and minimal surface defects—ideal for bakery/culinary use needing uniform appearance and taste.
- 2. How is aflatoxin level controlled in walnut production?
- Aflatoxin is measured via HPLC or rapid test kits. Yunnan LQ applies EU/ISO 22241 limits (<4ppb), with each batch certified by third-party labs and internal HACCP/ISO protocols.
- 3. What is the benefit of vacuum packing for walnut kernels?
- Vacuum packaging with nitrogen flush minimizes oxidation and rancidity, ensuring shelf-life up to 18–20 months and better flavor/fatty acid stability.
- 4. Which ISO/FDA standards apply for premium walnut kernels?
- Key standards: ISO 9001:2015, ISO 22000 (food safety), FDA CFR 110/117 (US), HACCP, endorsed by major importers worldwide. Product safety and traceability depend on these systems.
- 5. What shelling ratio or “yield” means in this industry?
- Shelling ratio is the % of kernel weight per in-shell raw walnut; e.g., 57% means every 100kg in-shell yields 57kg kernels. Higher ratios reflect efficient, high-grade varieties and technology.
- 6. How do you verify “recipe ready walnut kernels” meet food industry norms?
- Recipe ready kernels must be laboratory-tested for aflatoxin, overall purity (>99.3%), microbial safety (TVC <1000cfu/g), and certified free of foreign matter per ANSI/ASTA standards.
- 7. Can kernel size, moisture, or aflatoxin level be customized for OEM customers?
- Yes. Size, moisture (
