A process for preparing granules, the process comprising the steps of: a) preparing an oil-in-water emulsion comprising i. a hydrophobic active substance, wherein the hydrophobic active substance is a flavour or a fragrance; ii. a water soluble biopolymer having a molecular weight below 100 KDa and devoid of emulsifying properties, wherein the water-soluble biopolymer: - is selected from the group consisting of dextrins, maltodextrins and corn-syrup, and - is used in an amount of from 10 to 70% by weight, relative to the total weight of the emulsion; iii. hydrophilic solid particles that are insoluble in water; and iv. water; wherein the solid particles are selected from the group consisting of - silicon oxides; - metal oxides, hydroxides, salts of inorganic or organic acids and their mixtures; - silver nanoparticles; - magnesium and aluminium silicates; - latexes; - dietary fibers such as microcrystalline cellulose, lignin and chitin; - humic acid; - enteric polymers; and wherein the emulsion does not comprise a biopolymer chosen in the group consisting of gum Arabic, gelatine, modified starch and modified cellulose; b) spray-drying the emulsion obtained in step a) so as to obtain granules. a) preparing an oil-in-water emulsion comprising i. a hydrophobic active substance, wherein the hydrophobic active substance is a flavour or a fragrance; ii. a water soluble biopolymer having a molecular weight below 100 KDa and devoid of emulsifying properties, wherein the water-soluble biopolymer: - is selected from the group consisting of dextrins, maltodextrins and corn-syrup, and - is used in an amount of from 10 to 70% by weight, relative to the total weight of the emulsion; iii. hydrophilic solid particles that are insoluble in water; and iv. water; wherein the solid particles are selected from the group consisting of - silicon oxides; - metal oxides, hydroxides, salts of inorganic or organic acids and their mixtures; - silver nanoparticles; - magnesium and aluminium silicates; - latexes; - dietary fibers such as microcrystalline cellulose, lignin and chitin; - humic acid; - enteric polymers; and wherein the emulsion does not comprise a biopolymer chosen in the group consisting of gum Arabic, gelatine, modified starch and modified cellulose; i. a hydrophobic active substance, wherein the hydrophobic active substance is a flavour or a fragrance; ii. a water soluble biopolymer having a molecular weight below 100 KDa and devoid of emulsifying properties, wherein the water-soluble biopolymer: - is selected from the group consisting of dextrins, maltodextrins and corn-syrup, and - is used in an amount of from 10 to 70% by weight, relative to the total weight of the emulsion; - is selected from the group consisting of dextrins, maltodextrins and corn-syrup, and - is used in an amount of from 10 to 70% by weight, relative to the total weight of the emulsion; iii. hydrophilic solid particles that are insoluble in water; and iv. water; - silicon oxides; - metal oxides, hydroxides, salts of inorganic or organic acids and their mixtures; - silver nanoparticles; - magnesium and aluminium silicates; - latexes; - dietary fibers such as microcrystalline cellulose, lignin and chitin; - humic acid; - enteric polymers; and b) spray-drying the emulsion obtained in step a) so as to obtain granules.
