7. FAQs: Technical Terms & Industry Practice
1. What defines "Light Halves" in walnut 1 kg without shell? [Grading]
Light Halves (also "Grade A halves") refer to unbroken walnut kernels with exceptionally light color and high oil content, meeting GB/T 20399-2021 class requirements for minimal imperfections and uniformity.
2. What are standard dimensions and sorting tolerances? [Size/Spec]
Halves must be ≥14mm at the widest point; quarters ≥7mm. Broken pieces ≤10% by weight permitted per ISO22000/HACCP grading.
3. How is food safety assured during processing? [Safety/ISO]
All lots are processed in BRC grade AA, ISO22000, and FDA CFR 110 compliant facilities. Each shipment is tested for total plate count, yeast/mould, Salmonella (negative), and Aflatoxin B1 (<2ppb).
4. What packaging is used and why? [Packaging]
Typically, vacuum-sealed or nitrogen-flushed 10–12.5kg PE food-grade bags are used to prolong shelf-life and prevent oxidation/contaminant contact, as per FDA and EU 10/2011/EU standards.
5. Can walnut no shell be used for allergen-free applications? [Allergen]
Yes, as long as the factory has both HACCP and GFCO allergen management, with no processing line overlap with other tree nuts (peanuts, almonds, cashews, etc.). Request COA for each lot.
6. What is the typical lead time and MOQ? [Supply Chain]
Standard orders (≥1000kg) are fulfilled in 7–12 days. Larger/seasonal orders (20MT+) may require contract lead time, with flexible logistics as per INCOTERMS 2020.
