The invention provides a process for powdering highly unsaturated fatty acid esters of ascorbic acid which are pasty and problematic in physical properties by a simple and easy means; highly unsaturated fatty acid esters of ascorbic acid which are improved in stability by powdering; and compositions containing the powdered highly unsaturated fatty acid esters of ascorbic acid. Specifically, a process for powdering a highly unsaturated fatty acid ester of ascorbic acid as represented by the general formula (I): RCO - A [wherein RCO- is acyl derived from a highly unsaturated fatty acid; and A is an ascorbic acid residue bonded through an -O- linkage resulting from an hydroxyl group of ascorbic acid], characterized by mixing a highly unsaturated fatty acid ester of ascorbic acid as represented by the general formula (I) with an aqueous solution of a water-soluble filler to form an emulsion and dehydrating and drying the emulsion by a spray drying method.
L'invention porte: sur un procédé de pulvérisation par un moyen simple et facile d'esters gras de l'acide ascorbique dont la pulvérisation améliore la stabilité; sur des compositions contenant lesdits esters gras; et spécifiquement sur un procédé de pulvérisation d'un ester gras de l'acide ascorbique de formule générale (I): RCO - A [dans laquelle: RCO- est un acyle dérivant d'un acide gras fortement insaturé; et A est un résidu de l'acide ascorbique fixé par une liaison O- résultant d'un groupe hydroxyle de l'acide ascorbique], et caractérisé par le mélange d'un ester gras de l'acide ascorbique de formule générale (I) avec une solution aqueuse d'une charge hydrosoluble pour former une émulsion; et déshydratation et dessiccation de l'émulsion par un procédé de séchage par atomisation
