1.5. Vitis vinifera L. (ID 2157)
The food that is the subject of the health claim is Vitis vinifera L. related to the following claimed effect: maintenance of normal venous blood flow.
Vitis vinifera L. is a liana which is cultivated for food use mainly for its fruits (i.e. grape).
The leaves of Vitis vinifera L. contain flavonoids (flavonols and anthocyans), tannins (catechins, procyanidins, ellagitannins) as well as hydroxycinnamic acid derivatives and, depending on the variety, different amounts of cyanogenic glycosides. The fruits contain tartaric acid, malic acid, anthocyans and tannins, as well as essential oils containing linalool, geraniol, nerol, α-terpineol and phenylethanol. In the skin of the fruits, trans-resveratrol and pterostilben, as well as dimers and oligomers, are found. The seeds of Vitis vinifera L. contain 6-20 % fat, of which around 55 % is linoleic acid and 37 % oleic acid, and are rich in oligomeric procyanidins (Blaschek et al., 2008).
The proposed conditions of use for this claim refer to the fruits, leaves and seeds, which are to be consumed in various forms and amounts, as well as to a specific leaf extract for which the flavonol content is given and the main flavonols were identified (i.e. quercetin-3-O-ß-D-glucuronide and quercetin-3-O-ß-glucoside). The references provided were related to extracts from red vine leaves, grape skin and grape seeds, respectively. In addition, monographs on Vitis vinifera L. and reviews on the effects of polyphenolic flavonoids were provided.
The Panel notes that from the information in the consolidated list and the references provided it is unclear to which specific preparation of Vitis vinifera L. the claim refers.
The Panel considers that the food, Vitis vinifera L., which is the subject of the claim, is not sufficiently characterised.
The Panel concludes that a cause and effect relationship cannot be established between the consumption of Vitis vinifera L. and the claimed effect considered in this section.
