Grape Seed Extract FAQ
- ●
What is Grape Seed Extract Powder?
Grape Seed Extract Powder is a concentrated ingredient derived from the seeds of grapes (Vitis vinifera). It is highly valued for its rich concentration of bioactive compounds, primarily Polyphenols, including Oligomeric Proanthocyanidins (OPCs).
- ●
What are Proanthocyanidins (OPCs) and Polyphenols?
Polyphenols are a broad category of plant compounds known for their antioxidant activity. Proanthocyanidins (specifically OPCs) are a major type of polyphenol found abundantly in grape seeds. They are considered among the most potent antioxidants derived from grapes and are linked to various health benefits, particularly cardiovascular and circulatory support.
- ●
How is your Grape Seed Extract standardized (e.g., % OPCs, % Polyphenols)?
Our Grape Seed Extract is standardized to guarantee consistent levels of key active compounds. Common specifications include a minimum percentage of Total Polyphenols (e.g., 90%, 95% by UV) and/or Oligomeric Proanthocyanidins (OPCs) (e.g., 85%, 95% by UV or sometimes specified by HPLC methods). Please check the specific product COA.
- ●
How are the OPC and Polyphenol levels verified?
Total Polyphenols and Proanthocyanidins (OPCs) are commonly measured using UV-Vis spectrophotometry according to standardized methods. High-Performance Liquid Chromatography (HPLC) can also be used for more detailed profiling or specific OPC quantification. Verified results are reported on the Certificate of Analysis (COA).
- ●
What part of the grape (Vitis vinifera) is used?
This extract is specifically derived from the seeds of the grape (Vitis vinifera), as they are the most concentrated source of Proanthocyanidins (OPCs) compared to the skin or pulp.
- ●
What extraction methods are typically employed?
Extraction commonly involves using food-grade solvents, typically a hydroalcoholic mixture (water and ethanol), to efficiently isolate the polyphenols and OPCs from the ground grape seeds. The extract is then purified and dried into a powder.
- ●
What are the primary B2B applications for Grape Seed Extract Powder?
It is a highly popular ingredient in dietary supplements for antioxidant support, cardiovascular health, circulatory support (vein health), and skin health. It’s also used in functional foods, beverages, and cosmetic formulations for its potent antioxidant properties.
- ●
How does Grape Seed Extract differ from Grape Skin Extract?
While both contain beneficial compounds, Grape Seed Extract is exceptionally rich in Proanthocyanidins (OPCs). Grape Skin Extract is typically richer in other types of polyphenols like Resveratrol and Anthocyanins (which give red grapes their color).
- ●
Is your Grape Seed Extract tested for contaminants?
Yes, ensuring safety and purity is critical. Each batch undergoes rigorous testing for heavy metals (Lead, Arsenic, Cadmium, Mercury), pesticide residues, microbial limits (TPC, Yeast/Mold, E. coli, Salmonella), and residual solvents to meet international quality standards.
- ●
Is the manufacturing process GMP certified?
Yes, our Grape Seed Extract Powder is produced in facilities compliant with Good Manufacturing Practices (GMP), guaranteeing consistent quality, process control, safety, and traceability.
- ●
Do you offer certified Organic Grape Seed Extract?
Yes, certified Organic Grape Seed Extract options, sourced from organically grown grapes and processed according to organic standards, are often available. Please specify if you require the certified organic grade.
- ●
Are Halal or Kosher certifications available?
Halal and/or Kosher certifications are frequently available for our Grape Seed Extract. Please inquire with our sales team about the certification status for the specific product grade or batch.
- ●
What are the storage guidelines and shelf life?
Store the powder in a cool (below 25°C), dry place, protected from light and moisture, in its original tightly sealed container. Proanthocyanidins are relatively stable but benefit from proper storage. Typical shelf life is 24-36 months.
- ●
What is the appearance, taste, and solubility?
Grape Seed Extract Powder is typically a fine, reddish-brown to purplish-brown powder. It has a characteristic astringent and slightly bitter taste. Its solubility in water varies depending on the OPC concentration and processing but is generally moderate to good, often forming colloidal solutions.
- ●
Is Grape Seed Extract suitable for vegan/vegetarian products?
Yes, being derived entirely from grape seeds (plant source) and processed without animal inputs, our Grape Seed Extract Powder is fully suitable for vegan and vegetarian formulations.
- ●
What technical documentation do you provide to B2B buyers?
We provide comprehensive technical documentation including Certificates of Analysis (COA detailing OPC/Polyphenol content by UV/HPLC), Specification Sheets, MSDS, Allergen Statements, and relevant certifications (GMP, Organic, Halal, Kosher where applicable).
- ●
