Our Pumpkin Seed Protein Powder is a functional plant-based ingredient derived from high-quality Cucurbita pepo seeds. Unlike standard market varieties that often present a dark green color and gritty texture, our proprietary cold-pressed extraction process yields a distinct Light Yellow Fine Powder.
This aesthetic advantage is critical for formulators. It allows for higher inclusion rates in vanilla, fruit, or neutral-flavored applications without negatively impacting the finished product’s visual appeal (no “muddy” or dark green cast).
As a dedicated manufacturer and exporter, we control the entire supply chain—from seed selection to final milling. This ensures a consistent amino acid profile and strictly controlled contaminant levels, making it an ideal clean-label ingredient for the global food, beverage, and dietary supplement industries.
We offer two distinct grades tailored for different processing environments. Use the table below to select the right specification for your formulation.
| Parameter | Specification A (60%) | Specification B (70%) | Test Method |
|---|---|---|---|
| Protein Content (Dry Basis) | ≥ 60.0% | ≥ 70.0% | Kjeldahl / Dumas |
| Appearance | Light Yellow Fine Powder | Light Yellow Fine Powder | Visual |
| Particle Size | 95% pass 80 Mesh | 98% pass 100 Mesh | GB/T 5507 |
| Moisture | ≤ 8.0% | ≤ 8.0% | GB 5009.3 |
| Ash | ≤ 9.0% | ≤ 8.0% | GB 5009.4 |
| pH (10% Solution) | 6.0 – 8.0 | 6.0 – 8.0 | pH Meter |
| Bulk Density | 0.35 – 0.55 g/ml | 0.40 – 0.60 g/ml | USP <616> |
| Heavy Metals (Pb) | < 1.0 ppm | < 1.0 ppm | ICP-MS |
| PAHs (Sum of 4) | < 10 ppb (EU Compliant) | < 10 ppb (EU Compliant) | GC-MS |
| Microbiology (TPC) | < 10,000 CFU/g | < 10,000 CFU/g | AOAC |
Safety is the primary concern for plant-based ingredients, particularly regarding environmental contaminants.
Strict PAHs Control (EU Standard) Polycyclic Aromatic Hydrocarbons (PAHs) are a known risk in pumpkin seed products due to improper drying. We utilize indirect heat drying and advanced filtration technologies to ensure our product meets stringent EU regulations (Sum of 4 PAHs < 10 ppb), eliminating contamination risks.
Heavy Metal Management Sourced from controlled growing regions away from industrial pollution, our seeds undergo regular third-party testing. We ensure Lead, Arsenic, Cadmium, and Mercury levels are consistently well below international limits (< 1.0 ppm for Lead).
Certifications & Statements
Alt Text: Comparison of pumpkin seed protein solubility in beverages vs bakery bars
The 70% specification is refined to reduce fiber content and improve particle size distribution (100 mesh).
The 60% specification retains a higher proportion of dietary fiber and complex carbohydrates.
Q: What is the main difference between 60% and 70% pumpkin seed protein?
A: The primary difference is purity and fiber content. The 70% grade is further processed to remove fiber, resulting in a finer powder (100 mesh) with better dispersibility for beverages. The 60% grade retains more fiber, making it ideal for texture improvement in bakery and bars.
Q: Is your pumpkin seed protein soluble in water?
A: It is highly dispersible rather than fully soluble (like whey isolate). Our 70% grade is milled to a fine mesh to ensure smooth suspension in plant milks and shakes without gritty sedimentation.
Q: How do you ensure the product does not contain high levels of PAHs?
A: We strictly control the drying and roasting temperatures during seed pre-treatment. Every batch is tested using GC-MS to ensure PAHs are compliant with EU regulations (<10 ppb) before release.
Q: Do you serve distributors or just end manufacturers?
A: We serve both. As a manufacturer, we offer flexible MOQs for trial orders and tiered pricing for full container loads for distributors and large brands.
