Product Introduction
Premium Grape Seed Extract Powder 95% OPC | Antioxidant-Rich Botanical Ingredient for Nutraceuticals & Cosmetics
Grape Seed Extract Powder (≥95% oligomeric proanthocyanidins (OPC)) Pharmaceutical Grade Xi'an Yanxi Biotech Co., Ltd. Advanced water-ethanol extraction and chromatographic purification. As of 2010, we have a vertically integrated production system for premium Vitis vinifera L. seeds, which is ISO 22000, HACCP, Kosher and Halal certified, with heavy metal concentration below 10 ppm and microbial loads below 1,000 cfu/g. We export to over 100 nations, presenting 25 tonne ability monthly in 1kg foil luggage, 5kg containers and 25kg fibre drums, added within 72 hours from our temperature managed facilities.

Superior Bioactive Performance
Thru ORAC testing at third party laboratories, our product is 20× stronger than vitamin C and 50× stronger than vitamin E in antioxidant potency. The 95% minimum OPC concentration is targeted toward free radical scavenging, protection of collagen cross-linking and prevention of melanin synthesis.
Manufactured in GMP-certified facilities with patented low-temperature extraction technique, the powder is fully bioactive and has a 100% pass-through 80-mesh particle size for easy dissolution. Loss on drying is less than five% and ash content is max. Five%. Shelf stability is guarantyd for 2 years when saved under 25°C in sealed bins.

Versatile Application Solutions
This extract is a 300-500 mg daily-dose capsule used by formulators in dietary supplements for cardiovascular health and skin health support. In cosmetics, 0.5-3% concentrations increase anti-aging serums, UV protection creams and pigmentation-correcting products by decreasing tyrosinase activity and stabilising dermal elastin.
The powder is soluble in water (>95% at 25°C) and dispersible in ethanol, making it suitable for use in functional beverages, protein shakes, and topical emulsions. The neutral pH (4.5-6.5) maintains formulation stability and will not interfere with colour in clear liquid applications.
Grape seed extract powder is used by useful meals producers searching for clean-label antioxidants for top class chocolate, fortified drinks and electricity bars. Heat balance as much as eighty °C makes possible the pasteurisation without degradation of proanthocyanidin oligomers.
Rigorous Quality Assurance
HPTLC fingerprint validation of each batch of production confirms Vitis vinifera authenticity and excludes adulterants such as peanut skin or pine bark. Dual-method potency verification: Folin-Ciocalteu total polyphenol analysis and HPLC-GPC molecular weight distribution profiling.
ICP-MS screening with tight limitations of lead <3.0 ppm, arsenic <1.0 ppm, cadmium <1.0 ppm. Testing for pesticide residues in accordance with USP <561> and EU 396/2005. Testing for solvent residues verifies water-ethanol extraction, no methanol/acetone.
Facilities accredited by SGS are equipped with real-time environmental monitoring, automated CIP systems, and nitrogen-flushed packaging to prevent oxidative degradation. Each shipment includes a Certificate of Analysis, MSDS and allergies declarations.

FAQ
Q: What makes grape seed proanthocyanidins one of a kind from others?
A: Our extract only contains B-type oligomeric links, which are exclusive to Vitis vinifera, while peanut skin has A-type linkages. HPLC-GPC confirms excellent bioavailability with 70% dimers-tetramers.
Q: How does particle length have an effect on formulation performance?
A: Eighty mesh homogeneity allows for short hydration in bloodless water and eliminates nozzle clogging in high velocity encapsulation. In addition, smaller particles improve transdermal penetration of the cosmetic bases.
Q: Can this product be utilized in clean beverage structures?
A: Yeah. Our microfiltration technique eliminates haze-causing tannin polymers, giving <5 NTU turbidity in pH 3-7 solutions after 24-hour dissolution.
Q: What garage situations will preserve efficiency?
A: After each use, seal containers and keep at 15-25°C / 59-77°F with <60% relative humidity. No effect on flowability when stored refrigerated for 36 months.
