Claims
- 1. A barrier for inhibiting moisture migration in a multi-domain food system comprising at least one hydrocolloid, wherein the barrier is placed between regions of differing water activity.
- 2. The barrier according to claim 1 wherein the at least one hydrocolloid is selected from the group consisting of cold water swelling starches, carageenan, gums, methylcellulose, propylene glycol alginate and pectin.
- 3. The barrier according to claim 1 wherein the at least one hydrocolloid is a water swellable hydrocolloid.
- 4. The barrier according to claim 1 wherein the at least one hydrocolloid is at least one cold water swellable starch.
- 5. The barrier according to claim 1 wherein the at least one hydrocolloid is at least one cold water swellable edible powder.
- 6. The barrier according to claim 5 wherein the at least one hydrocolloid is a blend of at least two cold water swellable edible powders.
- 7. The barrier according to claim 5 wherein the particle size of the powder is less than about 150 microns.
- 8. The barrier according to claim 5 wherein the at least one cold water swellable edible powder is a modified cold water swellable starch.
- 9. The barrier according to claim 5 wherein the at least one cold water swellable edible powder is a blend of at least two modified cold water swellable starch.
- 10. The barrier according to claim 1 further comprising one or more components selected from the group consisting of films, adhesive agents, flow aides, lipids, waxes, proteins and coatings.
- 11. A food system having reduced moisture migration between a region of higher water activity and a region of lower water activity, the food system comprising a moisture barrier having water swellable material.
- 12. The food system according to claim 11 wherein the water swellable material is at least one hydrocolloid.
- 13. The food system according to claim 12 wherein the at least one hydrocolloid is at least one starch.
- 14. The food system according to claim 13 wherein the at least one starch is at least one modified cold water swellable starch.
- 15. The food system according to claim 11 wherein the water swellable material is at least one cold water swellable starch.
- 16. The food system according to claim 11 wherein the water swellable material is a blend of at least two cold water swellable starches.
- 17. A method of inhibiting moisture migration in a food system comprising the step of applying a hydrocolloid containing barrier between regions of differing water activity.
- 18. The method according to claim 17 wherein the hydrocolloid containing barrier is comprised of at least one cold water swellable powder.
- 19. The method according to claim 17 further comprising the step of placing the hydrocolloid containing barrier in solution prior to application of the barrier between the regions.
- 20. The method according to claim 17 further comprising the step of applying the hydrocolloid containing barrier as a powder between the regions of differing water activity.
