Introduction
Pumpkin Seed Extract is a concentrated botanical ingredient derived from the dried seeds of Cucurbita pepo L. through water/ethanol extraction and spray drying. It contains phytosterols, unsaturated fatty acids, proteins, amino acids, and essential minerals, including zinc, magnesium, and iron. Scientific studies have shown substantial phytosterol levels (128–2087 mg/100 g) with a unique Δ7-sterol profile and have demonstrated antioxidative, hypoglycemic, anticancer, antihypertensive, and anti-inflammatory activities.
Pumpkin Seed Extract Powder supplied by Huilin is manufactured under strict quality control, supported by full documentation including COA, MSDS, and batch traceability. We offer private label, OEM, and ODM services with competitive pricing and reliable supply chain support for bulk wholesale customers worldwide.

Process Flow
Pumpkin Seed Extract Powder is produced through a controlled hydroalcoholic extraction and spray drying process:
Key Process Steps:
- Sourcing – High-quality dried pumpkin seeds (Cucurbita pepo L.) are sourced from certified suppliers
- Cleaning & Dehulling – Seeds are cleaned and dehulled to remove impurities and unwanted components
- Extraction – Dehulled seeds undergo ethanol/water extraction to isolate bioactive compounds
- Filtration – Extract is filtered to remove particulate matter and insoluble residues
- Concentration – Extract is concentrated under reduced pressure to optimize active content
- Spray Drying – Concentrated extract is spray dried to produce a fine, free-flowing powder
- Quality Control – Each batch is tested for fatty acids, phytosterols, loss on drying, heavy metals, and microbial limits
- Packaging – Powder is packaged under controlled conditions in moisture-proof containers

Frequently Asked Questions (FAQ)
Q: Is Pumpkin Seed Extract Powder suitable for use in gummies or chewable tablets?
A: Yes, the powder is compatible with gummy and chewable tablet formats. Its mild nutty flavor and fine particle size allow for good incorporation. We recommend conducting small-scale trials to confirm texture and stability with your specific base formulation.
Q: Does Pumpkin Seed Extract Powder have a strong odor or taste?
A: The powder has a mild, characteristic nutty/seed-like odor and taste. It does not impart a strong or unpleasant flavor, making it suitable for blends where flavor masking is not a primary concern. For sensitive applications, flavor systems can be adjusted accordingly.
Q: Is this extract available in organic grade?
A: Organic-grade pumpkin seed extract is available upon request, subject to certification and sourcing availability. Please contact our sales team to discuss organic options for your specific requirements.
Q: What is the difference between pumpkin seed extract powder and pumpkin seed oil powder?
A: Pumpkin seed extract powder contains a broader range of water-soluble and alcohol-soluble bioactive compounds, including phytosterols, proteins, and minerals, in addition to fatty acids. Pumpkin seed oil powder is primarily a lipid-based ingredient focused on fatty acid content. Our extract powder provides a more comprehensive nutrient profile.
Q: Does the extract contain cucurbitacin or other bitter compounds?
A: Standard processing of pumpkin seed extract significantly reduces cucurbitacin content to non-bitter levels, resulting in a mild, palatable powder.
Q: Can this extract be used in beverage applications?
A: Yes, the powder can be incorporated into beverages. Due to its partial water solubility, it is best suited for suspension-type drinks or smoothie mixes rather than clear solutions. We recommend using a stabilizer system for ready-to-drink formats.
