APPARATUS AND METHOD FOR PRODUCING A THREE-DIMENSIONAL FOOD PRODUCT
A freeform fabrication system for the production of an edible three-dimensional food product from digital input data is disclosed. Food products are produced in a layer-by-layer manner without object-specific tooling or human intervention. Color, flavor, texture and/or other characteristics may be independently modulated throughout the food product. In addition, in some cases, the food products may further undergo one or more post-processing steps.
1 . A method for making an edible component comprising:
depositing successive layers of a food material according to digital data that describes the edible component; and
applying to one or more regions of the successive layers of food material one or more edible binders that bond the food material at said one or more regions to form said edible component,
wherein the food material comprises 25-75% by weight polysaccharide and 25-75% by weight monosaccharide and/or disaccharide, based on the total weight of the food material.
2 . The method of claim 1 , wherein the polysaccharide comprises a starch or modified starch.
3 . The method of claim 2 , wherein the modified starch is a modified food starch.
4 . The method of claim 1 , wherein the polysaccharide comprises maltodextrin.
5 . The method of claim 1 , wherein the monosaccharide and/or disaccharide comprises fructose, glucose, sucrose, or a combination thereof.
6 . The method of claim 1 , wherein the monosaccharide and/or disaccharide comprises confectioner's sugar.
7 . The method of claim 1 , wherein the monosaccharide and/or disaccharide comprises fructose.
8 . The method of claim 1 , wherein the food material further comprises 1-30% by weight sugar alcohol, based on the total weight of the food material.
9 . The method of claim 8 , wherein the sugar alcohol comprises one or more of glycerol, erythritol, xylitol, mannitol, sorbitol, inositol, volemitol, isomalt, maltitol, and lactitol.
10 . The method of claim 1 , wherein the edible component exhibits a flexural strength between about 0.5 MPa and about 2.0 MPa, when measured according to ASTM D790.
11 . The method of claim 1 , wherein the food material further comprises one or more flavorants.
12 . The method of claim 1 , wherein the digital data describes sequential cross-sectional layers of the edible component, the cross-sectional layers comprising a plurality of voxels.
13 . The method of claim 12 , wherein the sequential cross-sectional layers are generated from CAD data.
14 . The method of claim 12 , wherein the plurality of voxels vary in food material composition, color, flavor, or a combination thereof.
15 . The method of claim 1 , wherein one or more edible binders are applied to one or more regions of each of the successive layers of food material.
16 . The method of claim 1 , wherein unbound food material supports the edible component during formation of the edible component.
17 . The method of claim 1 further comprising infiltrating the edible component with an infiltrant.
18 . A method for making an edible component comprising:
depositing successive layers of a food material according to digital data that describes the edible component; and
applying to one or more regions of the successive layers of food material one or more edible binders that bond the food material at said one or more regions to form said edible component,
wherein the food material comprises 1-25% by weight seed crystals.
19 . The method of claim 18 , wherein the seed crystals comprise cocoa butter seed crystals.
20 . The method of claim 18 , wherein the cocoa butter seed crystals have a Type V crystal structure.
