Edible print substrates and methods of making and using the same
The embodiments disclosed herein relate to edible print substrates. The edible print substrates can include one or more starches, celluloses, dextrins, sugars, humectants or plasticizers, or emulsifiers, or combinations thereof. In certain instances, the edible print substrates include maltodextrin having a DE of between about 5 and about 20. The edible print substrates can also include glycerine. The edible print substrates can be formed into single layer and multi-layer constructions.
1. An edible print substrate, comprising:
a base layer comprising a base formulation, the base formulation comprising
between 15% and 40% by weight of one or more starches,
between 3% and 20% by weight of one or more celluloses,
between 10% and 24% weight of a dextrin and/or a maltodextrin having a DE of between 5 and 15,
between 10% and 30% by weight of one or more low melting point lipids, the one or more low melting point lipids each having a melting point of 95° F. or lower, and
between 1% and 8% by weight of one or more high melting point lipids, the one or more high melting point lipids each having a melting point of 158° F. or higher; and
a print layer comprising a coating formulation, the coating formulation comprising
between 15% and 40% by weight of one or more starches,
between 3% and 20% by weight of one or more celluloses, and
one or more of a corn syrup, corn syrup solids, a sweetener, or a sugar;
wherein the base layer is less absorbent to moisture and colorants than the print layer.
2. The edible print substrate of claim 1 , wherein the one or more starches of the base formulation comprises at least one of a tapioca starch, a corn starch, a wheat starch, a rice starch, a potato starch, or a derivative thereof.
3. The edible print substrate of claim 1 , wherein the one or more celluloses of the base formulation comprises at least one of a microcrystalline cellulose or a carboxymethyl cellulose.
4. The edible print substrate of claim 1 , wherein the base formulation further comprises an emulsifier.
5. The edible print substrate of claim 1 , wherein a thickness of the edible print substrate is between 100 microns and 250 microns.
6. The edible print substrate of claim 1 , wherein the base formulation further comprises a coloring agent.
7. The edible print substrate of claim 1 , wherein the base formulation further comprises a preservative.
8. The edible print substrate of claim 1 , wherein a pH of the base layer is between 4 and 5, and a pH of the print layer is between 6.5 and 7.5.
9. The edible print substrate of claim 1 , wherein the base formulation comprises between 14% and 20% by weight of the dextrin and/or maltodextrin.
10. The edible print substrate of claim 1 , further comprising:
an intermediate layer comprising an intermediate formulation, the intermediate formulation comprising
a starch,
a cellulose,
a low melting point lipid, the low melting point lipid having a melting point of 95° F. or lower,
a high melting point lipid, the high melting point lipid having a melting point of 158° F. or higher,
a dextrin and/or a maltodextrin having a DE of between 5 and 15, and
a humectant or plasticizer.
11. The edible print substrate of claim 1 , wherein the one or more low melting point lipids of the base formulation comprises at least one of a shortening or a coconut oil.
12. The edible print substrate of claim 1 , wherein the one or more high melting point lipids of the base formulation comprises calcium stearate.
13. A method of forming a multi-layer edible print substrate, comprising:
depositing a base formulation onto a carrier to form a base layer, wherein the base formulation comprises
between 15% and 40% by weight of one or more starches,
between 3% and 20% by weight of one or more celluloses,
between 10% and 24% by weight of a dextrin and/or a maltodextrin having a DE of between 5 and 15,
between 10% and 30% by weight of one or more low melting point lipids, the one or more low melting point lipids each having a melting point of 95° F. or lower,
between 1% and 8% by weight of one or more high melting point lipids, the one or more high melting point lipids each having a melting point of 158° F. or higher, and
a humectant or plasticizer; and
depositing a coating formulation to form a print layer, wherein the coating formulation comprises
between 15% and 40% by weight of one or more starches,
between 3% and 20% by weight of one or more celluloses,
one or more of a corn syrup, corn syrup solids, a sweetener, or a sugar, and
a humectant or plasticizer;
wherein the base layer is less absorbent to moisture and colorants than the print layer.
14. The method of claim 13 , further comprising depositing an intermediate formulation to form an intermediate layer wherein the intermediate formulation comprises:
a starch;
a cellulose;
a low melting point lipid, the low melting point lipid having a melting point of 95° F. or lower;
a high melting point lipid, the high melting point lipid having a melting point of 158° F. or higher;
a dextrin and/or a maltodextrin having a DE of between 5 and 20; and
a humectant or plasticizer.
