Patent ID: 6887493

Claim:
A food product comprising a plurality of solid nanospheres formed of a hydrophobic material, said hydrophobic material is selected from the group consisting of carnauba wax, candelilla wax, and mixtures thereof, each of said solid hydrophobic nanospheres encapsulated an effective amount of a first active agent contained therein, said plurality of nanospheres being homogenously dispersed within a moisture sensitive microsphere, said microsphere is formed of a moisture sensitive matrix material, said moisture-sensitive matrix material is selected from the group consisting of water soluble synthetic polymers, water dispersible synthetic polymer, starch derivative, natural gum, polysaccharide, protein, hydrocolloid and mixtures thereof, wherein said microsphere dissolves upon contact with said moisture to provide a burst of said nanospheres or said microsphere swells or softens to slowly release said nanospheres and said nanospheres release said active agent continuously thereafter for an extended period of time.
