Premium Grape Seed Extract Powder – Standardized 98% Proanthocyanidins Solution for Nutraceuticals and Functional Foods

Shaanxi Zhenhuacui Biotechnology Co., Ltd. develops HPLC-standardized pharmaceutical-grade Grape Seed Extract powder with 98% proanthocyanidins from premium Vitis vinifera seeds using spray-drying technology. With over 10 years of plant extraction experience and cGMP-certified facilities, our purplish-red powder is extracted utilizing supercritical CO₂ to preserve OPCs and polyphenol profiles. We provide flexible MOQ starting at 1 kg and expedited 10-day delivery for stock items to capsule, beverage, and cosmetic formulators demanding consistent quality and confirmed efficacy for antioxidant-rich formulations.

Product Descriptions

Our product uses precise extraction and quality methods for optimal bioavailability. Our food-grade formulation is purified many times to ensure component composition and batch-to-batch uniformity.

This standardized extract undergoes heavy metal screening (Pb <3ppm, As <1ppm), pesticide residue testing per EC 396/2005, and microbiological validation ensuring Salmonella/E. coli absence.

Application Areas

Your formulation demands define our delivery formats. Powder blends right in:

Nutritional supplements: capsules and tablets for immunological and cardiovascular health.

Functional beverages that need pH-stable ingredients below 3.5 include liquid concentrates and antioxidant waters.

Product Description: Anti-aging serums and creams with free radical scavenging characteristics for skin suppleness.

The Nutraceutical Blends include pressed sweets and solid drink powders that promote metabolic and vascular health.

The water-soluble grade avoids sedimentation in clear liquids, whereas standard extracts are good for encapsulation and tablet compression and flow.

Benefits

Among the several advantages of our proanthocyanidin-rich extract are:

Superior Free Radical Neutralization Capability: Offers Superior Protection for Cellular Structures Against Oxidative Stress Compared to Vitamin E.

Reduces the risk of cardiovascular disease by promoting healthy blood pressure and endothelial function and collagen cross-linking.

As a defense against skin aging, it blocks the enzymes elastase and collagenase, which slows down collagen breakdown and makes skin more supple.

Superbly Safe: Compatible with a Wide Range of Formulations and Non-Toxic at Appropriate Doses.

The formulation is quite versatile, since it may be used in a wide variety of dosage forms without compromising stability or effectiveness.

Certificate

Multiple widely known certificates ensure regulatory compliance at our facility:

cGMP (Current Good Manufacturing Practice)

FSSC22000 (Food Safety System Certification)

ISO9001 (Quality Management System)

HACCP (Hazard Analysis Critical Control Points)

HALAL and KOSHER Certifications

Organic Certification

Quality Control

Ensuring purity is an essential part of every production stage. The quality system is built around four pillars:

TLC verifies botanical origin and detects adulteration using less expensive fillers, whereas HPLC determines proanthocyanidin content with an accuracy of ±2%.

Gas chromatography is used to ensure that solvent residue testing complies with USP <467>, which states that ethanol/methanol residues must be less than 5000 ppm.

Contaminant Screening: ICP-MS analysis verifies pesticide panels in accordance with international norms, as well as heavy metal restrictions (Mercury <0.1ppm, Cadmium <1ppm).

Microbiological Control: Methods certified by the AOAC ensure that there is no pathogen tolerance and a Total Plate Count below 10,000 cfu/g.

Keeping an eye on peroxide levels (<10 meq/kg) prevents oxidative degradation while it's being stored, guaranteeing its effectiveness all the way throughout its shelf life.

COA

Each batch delivers with a detailed Certificate of Analysis:

HPLC chromatogram demonstrating 98% proanthocyanidin potency

ICP-MS heavy metal test results

Microbiological safety data

Conduct solvent residue analysis.

Physical attributes (appearance, wetness, particle size)

The batch number and production date

Request third-party laboratory verification for regulatory filings and customer audits.

Packaging and Transportation

Product integrity depends on handling. Grape Seed Extract powder is packaged in fiber drums with double-lined polyethylene bags and desiccant packs to prevent moisture absorption.

Standard 25 kilogram barrels are for industrial manufacturing, whereas 1 kg samples test formulations. All package has batch identification markings and tamper-evident seals.

To maintain proanthocyanidin stability, DHL, FedEx, and SF Express transport temperature-controlled. Sea freight is better for big shipments than air freight, which takes 5–7 days.

R&D Results

Our research team evaluates therapeutic applications thru controlled investigations. Recent studies show:

Stability testing shows 98% potency retention after 24 months at 25°C when kept as specified without color shift or clumping.

Magnesium stearate, microcrystalline cellulose, and silicon dioxide in compressed tablets interact neutrally in compatibility testing.

Enzymatic alteration improves water solubility for clear beverages, lowering turbidity by 78% while retaining antioxidant capacity in fermentation engineering studies.

Exhibition

We visit worldwide trade exhibitions to promote innovation and network with industry partners. Our annual participation showcases new standardized extracts and bespoke formulation capabilities, offering innovative extraction technology and OEM/ODM services to North American markets. You may inspect samples and discuss unique needs with our technical staff on these platforms.

FAQ

Q1: How is your 98% specification different from lower-potency extracts?

A: Our HPLC-verified 98% proanthocyanidin concentration maximizes therapeutic efficacy per serving, decreasing dose and boosting formulation cost-efficiency compared to 85-90% grades.

Q2: Is your extract water-soluble for clear beverages?

A: Our water-soluble grade with increased filtration prevents haze formation in functional fluids below pH 3.5, making it ideal for transparent drink compositions.

Q3: How do you store without oxidation?

A: Using multi-layer packing with oxygen-absorbing desiccants and nitrogen flushing during drum closing can keep peroxide levels below 10 meq/kg for 24 months.

Q4: Do you provide allergen-free certification?

A: Our facility has separate manufacturing lines free from common allergies (gluten, soy, dairy, nuts) and approved cleaning methods between batches.

Q5: What lead time applies to custom specifications?

A: Standard extract ships 98% of stock within 10 days. Green channel acceleration is offered for urgent orders of custom potencies or co-extracts, which take 25 days.
