Premium Wholesale Shelled Walnuts (Kernels) – Raw Extra Light & Light Bulk Supplier
Our farm-direct Shelled Walnuts (Juglans regia) represent the finest tier of commercial tree nuts. Harvested from high-altitude orchards with abundant sunshine and pure mountain water, our raw walnut kernels undergo gentle mechanical cracking, multi-stage optical color sorting, and X-ray foreign body detection. The resulting kernels feature a pale golden skin, crisp bite, mild natural sweetness without harsh astringency, and high nutritional density. They serve as a vital raw material for commercial baking, trail mix packaging, chocolate manufacturing, and plant-based dairy processing.
Why Source Wholesale Walnut Kernels From Us?
- Strict Color & Size Grading: Comprehensive range covering Extra Light Halves (80%+ Halves), Light Halves, Light Quarters, and Medium Pieces tailored for varied commercial applications.
- Advanced Optical & X-Ray Sorting: Automated multi-pass optical color selection and X-ray shell inspection ensure 99.9% shell-free purity and clean kernel presentation.
- Low Moisture & Oxidation Control: Moisture levels kept strictly under 5.0%, preventing rancidity, off-flavors, and free fatty acid elevation during maritime shipping.
- International Safety Accreditation: Fully certified under BRCGS, ISO22000, HACCP, USDA Organic, Halal, and Kosher quality standards.
Nutritional Excellence & Functional Health Benefits
Among botanical tree nuts, raw shelled walnuts stand out for their exceptional fatty acid spectrum and dense antioxidant matrix. Scientific evaluations confirm the valuable health profile of fresh Juglans regia kernels:
- High Essential Omega-3 (ALA): Provides approximately 9.0g of Alpha-Linolenic Acid per 100g, supporting cardiovascular function and anti-inflammatory pathways.
- Cognitive & Brain Support: Abundant polyphenols, gamma-tocopherol, and folate help protect neuronal membranes against oxidative fatigue.
- Heart-Healthy Lipid Profile: High ratio of polyunsaturated fatty acids (PUFAs) assists in regulating blood pressure and balancing LDL cholesterol.
- Culinary & Industrial Versatility: Excellent physical structure and oily crunch, ideal for breads, brownies, energy bars, and cold-pressed walnut oil extraction.

B2B Applications & Industrial OEM Manufacturing
Our raw and processed shelled walnuts cater to primary food processors and brand owners globally:
1. Commercial Baking & Confectionery
Extra Light and Light halves provide crisp texture and visual appeal in artisan sourdoughs, banana breads, brownies, and chocolate pralines.
2. Snack Mixes & Retail Packaging
Uniform 80%+ halves and quarters are ideal for high-end retail snack bags, dried fruit and nut trail mixes, and organic superfood lines.
3. Plant Oils & Beverage Processing
High oil yield pieces and quarters serve as a cost-effective matrix for cold-pressed extra virgin walnut oil and plant-based walnut milk drinks.
Packaging Options, Storage & International Logistics
Due to high polyunsaturated fat content, walnut kernels require precise protection against oxygen exposure and heat during international freight:
- Standard Industrial Bulk Packaging: 10 kg or 25 lb multi-layer vacuum foil bags flushed with food-grade nitrogen gas, enclosed in sturdy corrugated export cartons.
- OEM Private Label Retail Options: Nitrogen-flushed stand-up zipper pouches (200g, 500g, 1kg) or clear composite PET containers with custom artwork printing.
- Warehouse Storage Requirements: Store in cold storage ($0\text{–}5^\circ\text{C}$, relative humidity $<50\%$). Keep away from direct sunlight and volatile odorous products. Under cold storage, shelf life extends up to 18 months.
- Global Export Shipping: Shipped in reefer or temperature-monitored containers from major ports (Tianjin, Qingdao, or Shanghai), complete with Phytosanitary, Health, and COA documents.
Frequently Asked Questions (FAQ)
Q1: What is the difference between Extra Light (EL) and Light (L) walnut kernels?
Extra Light (EL) walnut kernels have a very pale, light golden skin color and a mild, non-bitter flavor, commanding a premium price for high-end retail and confectionery. Light (L) kernels are slightly darker golden-tan with the same rich nuttiness and nutritional value, offering a cost-effective option for commercial bakery and food manufacturing.
Q2: How do you protect bulk walnut kernels from rancidity during sea shipment?
We dehydrate the kernels to a low moisture level (≤ 5.0%) and vacuum seal them inside heavy-duty aluminum foil bags flushed with nitrogen gas. For long-distance sea transit across warm climatic zones, we strongly recommend temperature-controlled reefer container transport ($4\text{–}8^\circ\text{C}$) to prevent oil oxidation and Free Fatty Acid (FFA) elevation.
Q3: Can you provide third-party laboratory test reports for aflatoxins, heavy metals, and pesticides?
Yes. Every production batch undergoes rigorous third-party lab testing (SGS, Eurofins, or CIQ). We issue official Certificates of Analysis (COA) confirming that total aflatoxin levels are under 4.0 ppb, heavy metals meet global standards, and pesticide residues fully comply with EU MRL and US FDA import guidelines.
Q4: What is your Minimum Order Quantity (MOQ) and sample request procedure?
Our minimum order quantity for standard bulk 10kg cartons is 500 kg. For custom OEM private label pouches, the MOQ starts at 2,000 units per bag design. We gladly provide complimentary sample packages (250g–500g) for verified corporate buyers to inspect kernel color, size, moisture, and taste profile (buyer covers express courier freight).
