WATER- AND FAT-SOLUBLE MICRONUTIENT-STABILISED PARTICLES WITH AN ENTERIC POLYMER BARRIER

Particulate formulations containing one or more micronutrients such as iron supplements such as ferrous sulfate, fat or oil soluble vitamins such as vitamin A, D, and E, water soluble vitamins such as B vitamin family, and other micronutrients have been developed. These formulations resist oxidation and loss of bioactivity during processing, storage and cooking. The particles include one or more enteric polymers such as pH-sensitive polymers. To prevent oxidation, the iron supplements are encapsulated by a polymer such as hyaluronic acid ("HA"), preferably in a ratio of iron:HA of between 1:4 and 1:10), or mixed with a compound such as vitamin C. The resulting mixture is then dispersed in a solution of a enteric polymer, and manufactured using techniques such as spray drying or spinning disc atomization into particles into particles.
