Intended Use :

1. Applicability :

Authentication of selected Vaccinium species in dietary ingredients and dietary supplements

containing a single Vaccinium species using anthocyanin profiles.

2. Analytical Technique :

Any analytical technique(s) that measures the analytes of interest and meets the following

method performance requirements is/are acceptable.

3. Definitions :

Anthocyanins

Flavanoid phenolic compounds based on an oxonium ion ring structure (commonly pelargonidin, cyanidin, delphinidin, peonidin, petunidin, and malvidin), with one of the following substitutions at the 3, 5, or 7 site: simple sugars such as glucoside, arabinoside, or galactoside; oligosaccharides such as rutinoside, sambubioside, etc.; or acylation on sugar

with coumaric acid, acetic acid, etc.

Identification

Identification is the characterization of the substance being analyzed, including its chemical, mineral, or biological classification, as applicable. In many investigations the identity of the analyte is assumed

and the correctness of the assumption is merely confirmed.

Authenticity Panel

Authenticated materials to be used in the validation study for identity.
