Due to its volatile composition, a functional flavouring is fragile and feed manufacturing processes can be harsh (heat treatment, pressure, …). There are different situations, which require adapted technologies to ensure that a flavouring meets the specific needs for which it was developed. Developing a flavouring adapted to the feed according to its manufacturing constraints, the targeted animal species and physiological stages, or the necessary persistence, requires a high level of expertise and an in-depth knowledge of the sensory molecules, their associations and concentrations.
