1.7. Juice concentrate from berries of Vaccinium macrocarpon Aiton and Vaccinium vitis-idaea L. (ID 1125, 1288)
The food that is the subject of the health claims is a mixture of juice from American cranberry (Vaccinium macrocarpon Aiton) and lingonberry (Vaccinium vitis-idaea L.) related to the following claimed effect: defence against bacterial pathogens in the lower urinary tract.
According to the American Herbal Pharmacopeia and Therapeutic Compendium monograph (Upton, 2002), ―cranberry fruit‖ consists of the fresh or dried whole, crushed or powdered mature fruits of Vaccinium macrocarpon Aiton (American cranberry, large cranberry, bearberry). Vaccinium macrocarpon Aiton belongs to the genus Vaccinum of the family Ericaceae. Cranberry (Vaccinium macrocarpon Aiton) fruits contain anthocyanins, tannins, catechins, flavonol glycosides, proanthocyanidins, organic acids such as quinic, malic and citric acids, and sugars such as glucose and fructose (Blumenthal, 2003). Vaccinium vitis-idaea L. (lingonberry), also called ―European cranberry‖ or mountain cranberry, is a species closely related to Vaccinium macrocarpon Aiton.
From the information provided, the Panel notes that proanthocyanidins from cranberries and lingonberries have been indicated as being among the active constituents of the combination in relation to the claimed effect.
Only one human intervention study conducted with a juice product derived from berries of Vaccinium macrocarpon Aiton and Vaccinium vitis-idaea L. was provided (Kontiokari et al., 2001). The product used in the study was a 9.2 g juice concentrate containing 7.5 g juice concentrate from berries of Vaccinium macrocarpon Aiton and 1.7 g juice concentrate from berries of Vaccinium vitis-idaea L. diluted in 50 mL of water. No information was provided on the grade of concentration, on the proanthocyanidin content, on the proanthocyanidin profile or on any of the other compounds in the juice which was used for the intervention.
The Panel considers that the food, juice concentrate from berries of Vaccinium macrocarpon Aiton and Vaccinium vitis-idaea L., 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 a juice concentrate from berries of Vaccinium macrocarpon Aiton and Vaccinium vitis-idaea L. and the claimed effect considered in this section.
