Description
What it is. Substance aromatic preparation derived from Quercus robur L. / Q. pedunculata Ehrh. oak wood, obtained as an english creosote extract (CAS 71011-28-4). It is characterised by compounds typical of wood pyrolysis/extraction giving a smoky, woody flavour profile.
What it is for. This type of oak wood extract is generally used as a flavouring additive in feed, intended to influence palatability and organoleptic characteristics of the diet. As a sensory additive of category flavouring compounds, it would be used at low inclusion levels across species, without a specific nutritional function.
Points to watch. As a group 2b flavouring substance, it falls under additive-specific rules; no maximum inclusion level is given here and none should be assumed. Variability between extraction batches and compliance with the authorised specification and purity criteria should be checked before use.
