Walnut Protein Suppliers - Wholesale & Bulk

Nutrada lists GFSI-certified walnut protein suppliers with defatted grades containing ≥70% protein so procurement teams can compare specifications and request quotes directly. Find walnut protein suppliers offering full-fat and low-fat powder forms from China, California, and Chile.

Walnut Protein Types and Forms

Both grades contain vitamin E, ellagic acid, and melatonin. The defatted grade dominates B2B ingredient sales due to extended shelf life and higher protein density.

Walnut Protein Origin and Supply

China produces the majority of commercial walnut protein powder, leveraging its position as the world's largest walnut producer and offering competitive pricing for bulk grades.

California supplies premium-grade walnut protein from English walnut varieties, with consistent quality and established organic certification infrastructure supporting higher price positioning.

Chile, France's Grenoble region, and Turkey provide secondary supply sources, European walnut production is concentrated in mountain and foothill growing regions with cooler temperatures that support nut quality, though growing conditions vary considerably across origins.

Turkish suppliers focus primarily on domestic and Middle Eastern markets, while Chilean producers target North American buyers during the Northern Hemisphere's off-season harvest window.

Buyers evaluating nut-derived proteins often compare walnut protein alongside almond protein and cashew protein within the proteins category on Nutrada.

Bulk Walnut Protein

Walnut protein absorbs moisture rapidly above 65% relative humidity, requiring storage below 15°C in sealed containers to prevent rancidity. Defatted grades ship in 20-25kg multilayer kraft bags with polyethylene liners, stacked on 600-1000kg pallets for efficient handling. Ask suppliers for the peroxide value on the latest batch certificate before ordering, levels above 10 meq O₂/kg indicate oxidation that shortens shelf life below the stated 12-18 months for defatted grades.

Organic Walnut Protein

California holds the deepest organic walnut protein supply with dual USDA NOP and EU Organic certification available from established processors. China offers EU Organic certified walnut protein from certified walnut groves in Xinjiang and Yunnan provinces, though supply volumes remain limited compared to conventional grades. Turkish organic walnut protein targets the European market with EU Organic certification, while Chilean organic suppliers focus primarily on USDA NOP for North American buyers.

Walnut Protein Private Label

Consumer packaging includes 250g pouches, 500g resealable bags, and 1kg tins for retail protein powder brands. Private label MOQs typically start at 500kg per SKU due to specialized allergen handling requirements during packaging runs. Buyers must specify whether to highlight the omega-3 ALA content or antioxidant properties on the label before production starts, as these claims require different nutritional panel calculations.

Walnut Protein Manufacturers

Manufacturers concentrate in China's Shandong and Xinjiang provinces plus California's Central Valley for access to walnut processing infrastructure. Request batch-specific certificates of analysis showing protein content, peroxide values, and mandatory allergen declarations for tree nuts under both EU Regulation 1169/2011 and US FALCPA requirements.

Check microbiological reports for yeast, mold, and Salmonella limits, as walnut protein's residual oil content creates favorable growth conditions without proper processing controls.
