Pumpkin Seed Protein
Pumpkin Seed Protein is the seed-specific naming for protein isolate or concentrate extracted from Cucurbita pepo kernels, with typical protein content ranging from 60 to 75 percent.
It is the same base chemistry as pumpkin protein, but the seed-prefixed naming is preferred in label-friendly contexts and in raw, sprouted, or organic positioning.
The powder presents in shades from pale beige to deep green depending on hull retention, oil residue, and processing temperature.
We source bulk Pumpkin Seed Protein from top China manufacturers for our partners. The manufacturer is in Shaanxi. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
Pumpkin Seed Protein is graded by protein content, seed pretreatment, and colour.
Conventional concentrate at 60 to 65 percent protein covers most bakery and snack applications.
The 70 to 75 percent isolate grade serves sports nutrition, meal replacement, and clinical nutrition formats.
Raw and cold-pressed grades are processed below 45 degrees Celsius and command a premium in raw-foods and organic-vegan markets.
Sprouted pumpkin seed protein, produced by germinating seeds before pressing and milling, is positioned for whole-food and digestive-comfort claims.
Organic-certified material comes in 60, 65, and 70 percent protein versions, with traceable seed lots from Austria, China, and increasingly Eastern Europe.

How We Help Source Pumpkin Seed Protein
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Pumpkin Seed Protein out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Pumpkin Seed Protein together with other ingredients such as Collagen Peptide, Soy Protein Isolate and Fish Collagen Peptide into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Pumpkin Seed Protein is treated as a conventional food in the United States, the European Union, and Asia.
It is not a Novel Food in the European Union and does not require pre-market authorisation in the United States. Self-affirmed GRAS status is widely held by suppliers.
Organic certification under USDA NOP and EU 2018/848 is commonly available.
Kosher and Halal certificates are routinely issued. The ingredient is naturally vegan, gluten-free, and non-GMO when conventional seed stock is used.
Allergen declaration is not required in major jurisdictions, although suppliers should disclose shared-line risks with tree nuts, sesame, or peanut where applicable.
Manufacturing Process
Pumpkin Seed Protein production begins with hulled or partially hulled pumpkin seeds. Naked-seed cultivars such as Styrian pumpkin remain a preferred raw material because no dehulling is needed.
The seeds are cleaned, optionally roasted at low temperature for flavour development, and pressed mechanically to remove most of the oil.
The defatted press cake, holding 35 to 50 percent protein, is the starting point for further protein concentration.
For the concentrate grade, the cake is milled, sieved, and standardised. For higher-protein isolates, water or mild alkaline extraction is followed by isoelectric precipitation near pH 4.5, washing, neutralisation, and spray-drying.
Raw and cold-pressed grades skip thermal steps wherever possible and rely on mechanical separation and low-temperature drying.
