Blueberry extract
Blueberry extract suppliers and sourcing guide
Blueberry extract is made from the fruit of cultivated highbush blueberry (Vaccinium corymbosum) or wild lowbush blueberry (Vaccinium angustifolium). Fruit, juice concentrate or pomace is extracted with water or water-ethanol, often purified on resin to concentrate anthocyanins and other polyphenols, then spray dried. Brands buy it as powders standardized to anthocyanins or polyphenols; bilberry (Vaccinium myrtillus) is a separate ingredient.

Forms and grades of blueberry extract
Suppliers sell different products under the same name. Specify the one you need.
Anthocyanin-standardized extract
Resin-purified powder sold with a minimum anthocyanin percentage by a named HPLC or pH-differential method.
Polyphenol-standardized extract
Powder sold on total polyphenols by Folin-Ciocalteu, usually with a lower anthocyanin content than resin-purified grades.
Juice powder
Spray-dried juice or juice concentrate on a carrier, used for flavor and color more than for marker content.
Wild (lowbush) blueberry extract
Extract from Vaccinium angustifolium harvested in Maine and eastern Canada, sold separately from highbush extracts.
Organic
Extract from certified organic fruit, with the organic certificate tied to the lot.
What to check on the COA
Compare each result with your own specification when the lot arrives.
- Identity and adulteration (HPLC)
- Anthocyanin profile compared with blueberry references; added colorants or cheaper anthocyanin sources change the profile and are a known problem in berry extracts.
- Anthocyanin assay
- Total anthocyanins by HPLC or by the pH-differential method; results from the two methods are not interchangeable, so the COA should name the method.
- Heavy metals
- Lead, arsenic, cadmium and mercury by ICP-MS, checked against the buyer's limits and any Prop 65 exposure targets.
- Microbiology
- Total plate count, yeast and mold, E. coli or coliforms, and Salmonella.
- Pesticide residues
- Multi-residue pesticide screen, required for organic claims and commonly requested for conventional material.
- Physical tests
- Loss on drying, mesh or particle size, bulk density and, for extracts, the extract ratio, carrier and residual solvent.
Storage, lots and expiry
Storage and shelf life
Keep extract sealed in lined drums or foil bags in a cool, dry place away from light; anthocyanins degrade with heat, light and moisture, and the powder cakes once it picks up water. Reseal opened containers promptly. Shelf life or a retest date comes from the supplier's specification, with the anthocyanin assay repeated at retest.
Lots and expiry dates
Anthocyanin content varies with species, growing region and harvest, so check each lot's assay and method against your specification. Record whether the lot is highbush or lowbush, any carrier, and rotate stock first-expiry-first-out.
