<;p>; THE PRESENT INVENTION REFERS TO PROCESSES TO INCREASE THE STABILITY OF COMPOSITIONS COMPRISING OMEGA-6 POLYINSATURATED FATTY ACIDS AGAINST OXIDATION. THE PROCESSES INCLUDE THE FOLLOWING STAGES: (I) PROVIDE A STARTING COMPOSITION THAT INCLUDES AT LEAST ONE OMEGA-6 POLYINSATURATED FATTY COMPONENT; (II) PROVIDE A COMPOSITION OF LYSINE; (III) MIXING AQUEOUS, AQUEOUS-ALCOHOLIC OR ALCOHOLIC SOLUTIONS OF STARTING COMPOSITION AND COMPOSITION OF LYSINE,AND SUBSEQUENTLY SUBMIT THE RESULTING MIXTURE TO CONDITIONS OF DRYING BY SPRAYING, FORMING ASIacute; A SOUND SOLID PRODUCT COMPOSITION INCLUDING AT LEAST ONE SALT OF A CATISO DERIVED FROM LYSINE WITH AN ANIOATIC DERIVED FROM A POLYINSATURATED FATTY ACID: THE COMPOSITION OF THE PRODUCT IT PRESENTS A CONTENT OF SOLVENT SC SELECTED FROM THE FOLLOWING: SC? 5% BY WEIGHT, SCnbsp; ? 3% BY WEIGHT, SCnbsp; ? 1% BY WEIGHT,SC? 0.5% BY WEIGHT. nbsp; THE COMPOSITIONS OBTAINABLE THROUGH SUCH SPRAY DRYING PROCESSES AND THE USE OF SUCH COMPOSITIONS FOR THE MANUFACTURE OF FOOD, NUTRITIONAL AND PHARMACEUTICAL PRODUCTS ARE PRESENTLY UNDERTAKEN BY THE PRESENT >;<;p>;LA PRESENTE INVENCIÓ;N SE REFIERE A PROCESOS PARA AUMENTAR LA ESTABILIDAD DE COMPOSICIONES QUE COMPRENDEN Á;CIDOS GRASOS OMEGA-6 POLIINSATURADOS CONTRA LA OXIDACIÓ;N. LOS PROCESOS COMPRENDEN LAS SIGUIENTES ETAPAS: (I) PROPORCIONAR UNA COMPOSICIÓ;N DE PARTIDA QUE COMPRENDE AL MENOS UN COMPONENTE Á;CIDO GRASO OMEGA-6 POLIINSATURADO; (II) PROPORCIONAR UNA COMPOSICIÓ;N DE LISINA; (III) MEZCLAR SOLUCIONES ACUOSAS, ACUOSO-ALCOHÓ;LICAS O ALCOHÓ;LICAS DE COMPOSICIÓ;N DE PARTIDA Y COMPOSICIÓ;N DE LISINA, Y SOMETER POSTERIORMENTE LA MEZCLA RESULTANTE A CONDICIONES DE SECADO POR PULVERIZACIÓ;N, FORMANDO ASÍ; UNA COMPOSICIÓ;N DE PRODUCTO SÓ;LIDO QUE COMPRENDE AL MENOS UNA SAL DE UN CATIÓ;N DERIVADO DE LISINA CON UN ANIÓ;N DERIVADO A PARTIR DE UN Á;CIDO GRASO OMEGA-6 POLIINSATURADO
