Fremgangsmåte for å produsere fiskeforpellets med høyt oljeinnhold

摘要

A method for preparing high oil content fish feed pellets 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.
