Abstract

A solid product composition includes at least one salt of a cation derived from lysine with an anion derived from a polyunsaturated omega-3 fatty acid. The solid product composition is formed by (i) providing a starting composition containing at least one polyunsaturated omega-3 fatty acid component; (ii) providing a lysine composition; and (iii) admixing an aqueous, an aqueous-alcoholic or an alcoholic solution of starting composition and lysine composition, and subjecting resulting admixture to spray drying conditions subsequently, thus forming the solid product composition containing at least one salt of a cation derived from lysine with an anion derived from a polyunsaturated omega-3 fatty acid.
