Provided is a method for preparing high oil content fish feed pellets. The method comprises extruding a mixture of basic components for forming the matrix of fish feed pellets together with an additive which is solid under ambient conditions into porous pellets. The additive is a lipid or a fatty acid. Oil is then absorbed into the thus formed porous pellets to prepare the high oil content fish feed pellets. It is preferred that the additive is either a hydrogenated oil derived from animal or plant origin, or a lipid emulsifier such as a mono-, di- or tri-glyceride. The resulting pellets, which may include up to 50 % by wt. of oil, suffer very little oil leakage during storage and in use.
L'invention concerne un procédé pour préparer des granules de nourriture pour poissons à forte teneur en huile. Ce procédé consiste à extruder un mélange de composants de base pour former la matrice des granules avec un additif solide à température ambiante, et produire des granules poreux. Cet additif est un lipide ou un acide gras. L'huile est ensuite absorbée dans les granules poreux ainsi formés pour préparer les granules de nourriture pour poissons à forte teneur en huile. De préférence, l'additif est une huile hydrogénée d'origine animale ou végétale, ou un émulsifiant lipide tel qu'un mono-, di- ou triglycéride. Les granules ainsi obtenus, qui peuvent comprendre jusqu'à 50 % en poids d'huile, perdent très peu d'huile lors de leur stockage ou de leur utilisation.
