Abstract
A new delivery system for zinc compounds and the process for its preparation is disclosed, which has use in a variety of products including comestibles such as chewing gum compositions, confections, pharmaceuticals, food products such as vitamin preparations, dentifrice compositions and throat lozenges. More particularly, this invention relates to a process for preparing a zinc compound delivery system comprised of a zinc core material coated with a first hydrophilic coating comprising a hydrocolloid material and a second hydrophobic coating selected from the group consisting of fats, waxes and mixtures thereof. The delivery system provides enhanced masking of the bitter flavor characteristic of zinc compounds, as well as reduced grittiness with retained stability at the elevated temperatures of product formulation.
