AI Technical Summary
Existing encapsulation methods for biologically active substances like polyunsaturated fatty acids in foods are inadequate due to instability, incompatibility with food, and poor shelf life, particularly in high-temperature processing and long-shelf-life products, leading to oxidation and unpleasant odors.
Development of stable, food-grade microcapsules with a polymeric shell impermeable to water and oil, encapsulating active substances like polyunsaturated fatty acids, ensuring retention and controlled release.
The microcapsules maintain the integrity and biological activity of encapsulated substances, providing stability and controlled release, suitable for various food products without altering taste or odor, and suitable for vegetarian and vegan diets.
