The most apparent phytochemicals in these fruits are the anthocyanin pigments. Most anthocyanins are colorless at pH 4-6, and anthocyanin activity is reduced by heat, oxygen, ascorbic acid, light, and polyphenoloxidase. Anthocyanins in Vaccinium species are discussed in detail by Mazza and Miniati (1993). Other phe-nolics and flavonoids are present in varying amounts. Chlorogenic acid is the predominant phenolic compound in blueberries (Kader et al., 1996); benzoic acid is the primary phenolic in cranberry juice (Chen et al., 2001), and quercetin is found in most species as well. Berry flavonoid and phenolic composition differs greatly from that in leaves. Geographic and cultivar variations are significant in blueberries, while geographic differences may be less significant for cranberries.
