The present invention relates to processes for increasing the stability of compositions comprising polyunsaturated omega 6 fatty acids against oxidation. The processes comprise the following steps: (i) providing a starting composition comprising at least one polyunsaturated omega 6 fatty acid component (ii) providing a lysine composition (iii) admixing aqueous aqueous alcoholic or alcoholic solutions of starting composition and lysine composition and subjecting resulting admixture to spray drying conditions subsequently thus forming a solid product composition comprising at least one salt of a cation derived from lysine with an anion derived from a polyunsaturated omega 6 fatty acid the product composition exhibiting a solvent content SC selected from the following: SC < 5 wt% SC < 3 wt% SC < 1 wt% SC < 0.5 wt%. Compositions obtainable by such spray drying processes and use of such compositions for the manufacture of food nutritional and pharmaceutical products are further comprised by the present invention.
