1. A solid product composition, comprising:
at least one salt of a cation derived from lysine with an anion derived from a polyunsaturated omega-3 fatty acid, said solid product composition formed by:
admixing an aqueous, an aqueous-alcoholic or an alcoholic solution of a starting composition comprising at least one polyunsaturated omega-3 fatty acid component and a lysine composition, and subjecting a resulting admixture to spray drying conditions subsequently, thus forming the solid product composition comprising at least one salt of a cation derived from lysine with an anion derived from a polyunsaturated omega-3 fatty acid;
wherein the solid product composition has a solvent content of less than 5 wt %, and
wherein at least 90 wt % of the solid product composition consists of one or more salts of cations derived from lysine with anions derived from one or more polyunsaturated omega-3 fatty acids and other fatty acids.
