European Bilberry Extract Guide Addresses Quality and Sourcing

Shaanxi Ruiwo Phytochem Co., Ltd. has published a guide for business-to-business (B2B) buyers of European bilberry extract (Vaccinium myrtillus L.), focusing on quality assessment and purchasing considerations. The company advises that a high anthocyanin content alone is insufficient to determine the extract's quality and suitability.

The guide highlights that European bilberry extract is derived from Vaccinium myrtillus L., a plant known for its rich concentration of anthocyanins. These compounds are responsible for the fruit's deep blue-purple color. Shaanxi Ruiwo Phytochem states that for optimal ingredient quality, buyers must evaluate botanical identity, anthocyanin profile, extraction process, analytical methods, stability, and batch consistency.

Distinctions are drawn between European bilberry (Vaccinium myrtillus) and cultivated blueberries (Vaccinium corymbosum), noting differences in both botanical classification and anthocyanin profiles. The company stresses the importance for buyers to ensure they procure the specified plant part and material, and that product specifications and analytical methodologies are clearly defined.

Buyers are advised to verify botanical identity (Vaccinium myrtillus L.), specify the required anthocyanin content and analytical method (requesting HPLC documentation), obtain a Certificate of Analysis (COA) for the specific batch, and consider contaminant testing for heavy metals, microbiological parameters, and pesticide residues, depending on the application. Stability factors such as moisture, light, temperature, oxygen, and packaging are also noted as critical for maintaining anthocyanin integrity.

European bilberry extract is utilized in dietary supplements and other botanical ingredient applications, often marketed for antioxidant properties and eye health support. Its applications span the food and dietary supplement industries.
