Abstract
A method for recovering fish oil from aquatic biomass under cold conditions, the method comprising the steps of; providing an aquatic biomass; producing a minced aquatic biomass by mincing the aquatic biomass; providing an aqueous suspension of the minced aquatic biomass by mixing and/or homogenizing the minced aquatic biomass in an aqueous solution; adjusting the pH of said aqueous suspension to an extreme high pH or an extreme low pH; separating the aqueous suspension into a supernatant comprising a lower density emulsion fraction substantially comprising oil, aqueous solution and emulsified proteins, and a higher density fraction comprising substantially solubilized proteins, and optionally a pellet comprising collagenous components; collecting the lower density emulsion fraction; separating the lower density emulsion fraction into an oil phase and an aqueous phase; and collecting the oil from said oil phase.
