1.5. Flavonoids in cranberry juice (ID 1804)
The food constituent that is the subject of the claim is flavonoids in cranberry juice related to the following claimed effect: “antioxidativity”.
Flavonoids are polyphenolic substances naturally present in vegetables and fruits, and in their products. The group of flavonoids is large, with several hundred compounds belonging to subgroups of flavanones, flavonols, flavan-3-ols (such as proanthocyanidins), flavonones, isoflavonoids and anthocyanins. Cranberries typically contain high amounts of anthocyanins, flavonols and procyanidins (Kahkonen et al., 2001). The flavonoid content in cranberry juice is measurable by established methods, and conditions of use are provided for flavonoid content (5 mg/100 g). The amount and profile of flavonoids in cranberry juice vary according to the cranberry species (e.g. Vaccinium macrocarpon Aiton, Vaccinium oxycoccos L.), growing conditions and differences in the juice making procedure.
The only reference provided for the scientific substantiation of the claim which assessed the effects of cranberry juice consumption on markers of oxidative damage in humans did not provide a quantitative indication of the flavonoid content nor any qualitative information about the flavonoid profile in the cranberry juice used for the intervention (Ruel et al., 2005).
The Panel considers that the food constituent, flavonoids in cranberry juice, which is the subject of the claim, is not sufficiently characterised in relation to the claimed effect considered in this section.
The Panel concludes that a cause and effect relationship cannot be established between the consumption of flavonoids in cranberry juice and the claimed effect considered in this section.
Warunki i możliwe ograniczenia stosowania oświadczenia
Cranberry drink with flavonoid content of 5mg/100g.
The flavonoids in the cranberry drink come from the cranberry juice concentrate that is used in production of the drink. The drink has a 20% concentration of cranberry juice, so the flavonoid concentration is 20% of the flavonoid concentration in cranberry juice.
