Abstract
Alcohol water-based, edible ink formulations comprising scalenohedral calcium carbonate particles are provided. The calcium carbonate particles can act as a white pigment to impart white color properties to the edible ink formulations which provide improved print quality and durability. The edible ink formulations can be printed onto a variety of surfaces, including the surfaces of food products such as confectionery products and snack food products.

An edible ink formulation, comprising scalenohedral calcium carbonate particles present in an amount of from about 10 wt-% to about 30 wt-%, an alcohol present in an amount of from about 30 wt-% to about 55 wt-%, an aqueous solvent, and a binder,
- wherein the alcohol aqueous solvent comprises a high molecular weight alcohol selected from the group consisting of 1-butanol, 3-methyl-1-butanol (isoamyl alcohol), 2-butanol, and hexanol and a low molecular weight alcohol selected from the group consisting of isopropanol, 1-propanol, and ethanol on wt-% basis in a ratio of from about 7:1 to about 10:1,
- wherein the binder is selected from hydroxypropylmethylcellulose (HPMC), hydroxypropylcellulose (HPC), methyl cellulose, polyvinyl pyrrolidone, and sodium carboxymethylcellulose (NaCMC), and
- wherein the edible ink formulation, when applied as a film, exhibits a print durability score of less than 70.
An edible ink formulation, comprising scalenohedral calcium carbonate particles present in an amount of from about 10 wt-% to about 30 wt-%, an alcohol present in an amount of from about 30 wt-% to about 55 wt-%, an aqueous solvent, and a binder,
- wherein the alcohol aqueous solvent comprises a high molecular weight alcohol selected from C4, C5, and C6 alcohols and a low molecular weight alcohol selected from C2 and C3 alcohols on wt-% basis in a ratio of from about 7:1 to about 10:1, each of which is different from a diol,
- wherein the binder is selected from hydroxypropylmethylcellulose (HPMC), hydroxypropylcellulose (HPC), methyl cellulose, polyvinyl pyrrolidone, and sodium carboxymethylcellulose (NaCMC), and
- wherein the edible ink formulation, when applied as a film, exhibits a print durability score of less than 70.
