Nutrada lists GFSI-certified protein suppliers covering plant-based proteins and animal-based proteins in isolate, concentrate, and hydrolysate forms. Filter by protein type, processing form, protein percentage, certification, and MOQ to compare suppliers and request bulk wholesale quotes directly.
| Protein types | Plant-based (pea, rice, hemp, soy, faba bean, sunflower, pumpkin, oat, potato, lupin, chia, lentil, almond, cashew, walnut, mung bean, barley, watermelon seed, wheat, peanut), animal-based (whey, collagen) |
| Processing forms | Isolate (80-90%+ protein), concentrate (60-80%), hydrolysate |
| Functional forms | Powder, granules, textured (TVP) |
| Applications | Sports nutrition, meat alternatives, bakery, beverages, infant formula, dietary supplements |
| Certifications | GFSI (BRC, IFS, FSSC 22000), EU Organic, USDA NOP, non-GMO, Halal, Kosher, allergen-free facility |
| Packaging | 15, 20 and 25 kg kraft bags, food-grade drums, big bags (500-1000 kg) |
| Category | Proteins |
Suppliers on Nutrada cover plant-based proteins extracted from legumes, grains, seeds, and nuts, as well as animal-derived proteins including whey and collagen. The following protein types are available:
The processing form determines protein content, functionality, and cost. The table below covers the three main procurement forms available through suppliers on Nutrada:
| Form | Protein % | Best suited for |
| Concentrate | 60-80% | Bakery, meat analogues, cost-sensitive formulations |
| Isolate | 80-90%+ | Sports nutrition, beverages, high-protein bars |
| Hydrolysate | Variable | Infant formula, clinical nutrition, fast-absorbing sports formats |
For applications where taste or colour neutrality matters (beverages, dairy alternatives), confirm sensory profile alongside protein percentage. Pea protein isolate and rice protein concentrate are the most common pairing in plant-based blends targeting a complete amino acid profile.
Moisture content and microbiological load are the primary quality variables in bulk protein sourcing. Protein powders with moisture above 8% are susceptible to caking and microbial growth during storage; request a certificate of analysis confirming moisture, water activity (Aw), and total plate count alongside GFSI documentation. For allergen-sensitive formulations, confirm whether the processing facility handles soy, wheat, peanut, or milk proteins on shared lines, as facility-level cross-contact claims must align with your label declarations under EU Food Information Regulation 1169/2011.
Standard packaging is 20 to 25 kg kraft paper bags or food-grade drums. Big bag formats (500 to 1,000 kg) are available from larger manufacturers for high-volume production runs. Confirm particle size distribution if your process involves dry blending, as coarse and fine grinds behave differently in mixing and filling equipment.
EU Organic and USDA NOP certified options are available for most plant-based protein types on Nutrada, including pea, rice, hemp, sunflower, pumpkin, and chia. Organic certification is not available for all processing forms: organic isolates are less common than organic concentrates due to the additional extraction steps involved.
For whey and collagen, organic certification depends on the sourcing of the raw animal material and varies significantly by supplier. Confirm that both the raw material and the processing facility hold valid organic certifications before committing to any volume.
Private label protein formats range from single-ingredient powders in pouches and jars to custom blends for sports nutrition, meal replacement, and functional wellness applications. For multi-ingredient blends, define the protein source, processing form, and protein percentage in the product specification before requesting quotes, as these variables drive both formulation cost and label claims.
Suppliers on Nutrada offer private label services for both conventional and organic lines; MOQs typically start from 500 kg for standard formats and 1 MT or above for custom blends with flavouring and packaging.
Plant protein extraction is concentrated in Europe (pea protein from France and Belgium, potato protein from the Netherlands and Germany), Asia (soy and rice protein from China), and North America (soy and hemp protein from Canada and the US). Collagen and whey manufacturers are primarily based in Europe and South America, with Brazil and Argentina being major collagen sources.
GFSI-certified protein suppliers on Nutrada range from large commodity-scale manufacturers supplying isolates and concentrates to smaller specialty producers focused on single-origin proteins.
