Enclosing materials in natural transport systems
An edible composition, particularly an edible transport system, comprising an edible substance and a cross-linked matrix encapsulating the edible substance, the cross-linked matrix comprising (1) at least one edible polymer and edible particles or (2) a plurality of edible polymers.
1. An edible composition, comprising:
an edible substance;
a first edible polymer membrane encapsulating the edible substance; and
a second edible polymer membrane encapsulating the first edible polymer membrane,
wherein the first edible polymer membrane is comprised of at least one different edible polymer than the second edible polymer membrane, and wherein the first edible polymer membrane and the second edible polymer membrane form a melded interface;
wherein the melded interface comprises an electrostatic attraction between the first edible polymer membrane and the second edible polymer membrane; and wherein the edible substance is fully solid, partially solid, or viscous.
2. The edible composition of claim 1 , wherein the melded interface forms a moisture-retaining barrier layer.
3. The edible composition of claim 2 , wherein the moisture-retaining barrier layer retains moisture content of the edible substance.
4. The edible composition of claim 3 , wherein the first edible polymer membrane or the second edible polymer membrane has a moisture content of about 85%.
5. The edible composition of claim 4 , wherein the first edible polymer membrane or the second edible polymer membrane forms a moisture barrier, wherein the first edible polymer membrane or the second edible polymer membrane is substantially insoluble in water or other aqueous solution.
6. The edible composition of claim 1 , further comprising a separate and distinct edible barrier layer between the first edible polymer membrane and the second edible polymer membrane.
7. The edible composition of claim 1 , wherein, the edible substance comprises at least one of a liquid, powder, a gel, a foam, a solid, and combinations thereof.
8. The edible composition of claim 1 , wherein the first edible polymer membrane and the second edible polymer membrane each comprise a hydrocolloid selected from the group consisting of an alginate, an agar, a starch, a gelatin, carrageenan, xanthan gum, gellan gum, galactomannan, gum arabic, a pectin, a milk protein, a cellulosic, a carboxymethylcellulosic, a methylcellulosic, gum tragacanth and karaya, xyloglucan, curdlan, a cereal β-glucan, soluble soybean polysaccharide, a bacterial cellulose, a microcrystalline cellulose, chitosan, inulin, an emulsifying polymer, konjac mannan/konjac glucomannan, a seed gum, and pullulan.
9. The edible composition of claim 1 , wherein the edible substance is ice cream, frozen yogurt or gelato.
10. The edible composition of claim 1 , wherein the first edible polymer membrane, the second edible polymer membrane and/or the melded interface contain particles.
