Abstract:
A capillary feed marking instrument capable of producing edible colored indicia directly on a food substrate, said marking instrument comprising:an elongated, hollow, cylindrical body having a front end and a rear end a reservoir within said hollow cylindrical body for holding a quantity of an edible coloring liquid: a quantity of an edible coloring liquid disposed within said reservoir; a marking tip extending from said front end and communicating with said reservoir for producing a colored indicia on said food substrate; and a cap removably mounted on said front end of said marking instrument to cover said marking tip when not in use;said marking tip comprising a fibrous tip which allows said edible coloring liquid to be deposited by capillary action onto said food substrate,said edible coloring liquid comprising from about 90% to about 95% of a carrier solution, at least one edible dye in concentrations of from about 1.0% to about 10.0% by weight of said carrier solution, and at least one preservative in concentrations of from about 0.5% to 1.0% by weight of said carrier solution,wherein the viscosity and surface tension of said edible coloring liquid are sufficient to enable said liquid to be drawn out of said marking tip by capillary action and easily deposited onto said food substrate when said marking tip is contacted to said food substrate.
