What is Organic Pumpkin Seed Protein Powder?
Organic Pumpkin Seed Protein Powder is a clean-label, allergen-free, plant-based protein ingredient manufactured by ORGANICWAY. Derived from 100% organically cultivated pumpkin seeds (Cucurbita pepo), the seeds undergo cold-press oil extraction, leaving a nutrient-dense protein cake that is finely milled into a free-flowing, light green to greenish-brown powder available in two protein grades: ≥50% and ≥60% (dry basis).
Pumpkin seed protein stands out among plant proteins for its exceptional mineral content. It is a natural, concentrated source of zinc (immune function, protein synthesis), magnesium (muscle and nerve function), iron (oxygen transport and energy metabolism), phosphorus (bone health), and manganese (antioxidant enzyme function). This mineral profile makes pumpkin seed protein particularly valuable for sports nutrition, immune health, and micronutrient-enriched functional food formulations.
Nutritional & Functional Profile
Pumpkin seed protein contains all nine essential amino acids, with particularly notable levels of glutamic acid, arginine, leucine, and alanine. While lysine content is lower than animal proteins, the overall amino acid profile is more balanced than many plant proteins at equivalent processing levels. The powder also contains beneficial dietary fiber (15–25%) and healthy residual fats (10–15%) including oleic and linoleic fatty acids, contributing to satiety and overall nutritional value.

Formulation Notes
- Flavor: Mild, nutty, earthy — pairs naturally with chocolate, caramel, vanilla, peanut butter, and savory herb profiles. Suitable for both sweet and savory applications without strong flavor masking.
- Color: Natural light green to greenish-brown from chlorophyll and phytonutrients. For applications requiring neutral color, combine with lighter-colored proteins (rice, pea) or use pH-adjusted grades.
- Solubility: Best at pH 6.0–7.5; partially soluble (≥55%). Use high-shear mixing for beverage applications. Not recommended for use in clear or acidic (<pH 4.0) beverages without further processing.
- Mineral synergy: Pumpkin seed protein’s zinc + magnesium content can support “natural source of zinc” or “source of magnesium” label claims — verify against relevant regulatory thresholds for your market (e.g., EU Regulation 1924/2006 for nutrition claims).
- Protein blending: For complete amino acid profile, blend with pea or chickpea protein (25:75 ratio) to compensate for lower lysine.
FAQ
Q1: What is the protein content of your organic pumpkin seed protein powder?
A: Our organic pumpkin seed protein powder is available in two protein concentration grades: ≥50% and ≥60% protein by dry basis. The 60% grade is most commonly used in protein bars, supplements, and functional foods where a higher protein-to-weight ratio is required. The 50% grade is suited for applications where the natural fiber content (15–25%) is a desired nutritional attribute. Each batch is tested by AOAC 991.20 method, and a Certificate of Analysis is provided with every shipment.
Q2: Is pumpkin seed protein a complete protein?
A: Yes. Organic pumpkin seed protein contains all nine essential amino acids (histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine). While lysine is present at lower levels than animal proteins — making it a relatively limiting amino acid — the overall essential amino acid profile qualifies pumpkin seed protein as a complete protein source. For optimal amino acid balance in sports nutrition or clinical formulations, we recommend blending with pea or chickpea protein (25:75 pumpkin:pea ratio) to achieve lysine levels comparable to dairy protein quality.
Q3: What makes pumpkin seed protein stand out nutritionally?
A: Beyond protein content, organic pumpkin seed protein is exceptionally rich in key minerals: zinc (6–8 mg/100g, supporting immune function and protein synthesis), magnesium (280–340 mg/100g, supporting muscle and nerve function), iron (8–12 mg/100g, supporting oxygen transport), and phosphorus (~700–900 mg/100g, supporting bone health). These mineral levels can support regulatory nutrition claims in most markets (EU, US, Australia). Additionally, arginine — the dominant amino acid at ~4.8g/100g — has been studied for its role in vascular health and nitric oxide synthesis, offering sports nutrition differentiation claims.
Q4: Is your pumpkin seed protein allergen-free?
A: Yes. Pumpkin seeds are not listed as a food allergen under FDA’s Big 9 allergen regulation or EU Regulation 1169/2011 Annex II. Our organic pumpkin seed protein is naturally free from gluten, dairy, soy, peanuts, tree nuts, and sesame. It is processed in a dedicated allergen-free facility. This allergen profile makes it suitable for hypoallergenic formulations, multi-allergen-free product lines, and specialty dietary markets. Please request our allergen cross-contamination statement for full facility allergen status documentation.
Q5: What is the shelf life and how should pumpkin seed protein be stored?
A: Shelf life is 18–24 months from the manufacturing date when stored as directed. Store at temperatures ≤25°C in a cool, dry place with relative humidity below 60%. Keep sealed to prevent moisture absorption and oxidation of residual fatty acids. After opening, transfer to an airtight container and use within 30–60 days. For long-term storage or warehouse conditions in warm climates, nitrogen-flushed or vacuum-sealed packaging is recommended to minimize oxidative rancidity of the residual fat fraction (10–15%).
Q6: What is the minimum order quantity, lead time, and available documentation?
A: MOQ is 20 kg for sample and development orders, with no commitment to commercial volumes until product and formulation testing is complete. Standard lead time for commercial orders is 14–21 days from order confirmation. Documentation provided with each batch includes: COA (Certificate of Analysis), TDS (Technical Data Sheet), SDS (Safety Data Sheet), organic certificate, allergen cross-contamination statement, heavy metal test report, and pesticide residue test report. Kosher, Halal, and Non-GMO certificates are available on request.
