Multi component controlled release system for oral care, food products, nutraceutical, and beverages

This invention describes a system for releasing flavors or active ingredients in a sequence. It works by encapsulating ingredients within tiny, water-repelling nanospheres made of specific waxes, which are then themselves enclosed within larger, moisture-sensitive microspheres. When the product is consumed, the outer microspheres dissolve first, followed by a slow release from the inner nanospheres, providing a prolonged or changing flavor experience in food products.

Why it matters: Since 2003, advancements in food-grade nano- and micro-encapsulation technologies have made complex multi-layer release systems more efficient and scalable. This could make the precise, sequential flavor delivery described in the claims more economically viable for food products today.
