Vitis vinifera spp. Vinifera: Dry grape extract (mixture of seed and skin extract)

What it is. Dry grape extract (Vitis vinifera spp. vinifera), a mixture of seed and skin extracts as defined by the Council of Europe. It is characterised by a polyphenol content (expressed as catechin equivalent) and a proanthocyanidin content, together with a low water content.

What it is for. Sensory additive of functional group 2b (flavouring compounds), incorporated into feed as a premixture after being placed on the market as a preparation. It is generally used for its aromatic properties linked to grape phenolic compounds. It is authorised for all animal species except dogs.

Points to watch. The composition is defined by minimum thresholds for polyphenols, proanthocyanidins and anthocyanins/anthocyanidins, and a maximum water content threshold, as set out in the regulatory annex. Its identification and quantification rely on specific analytical methods (HPLC-UV, spectrophotometry); the natural variability of the extract should be taken into account during formulation.
