Various aspects of the disclosure relate to food comprising (i) an outer layer comprising flour or dough and (ii) a filling comprising a gel filling comprising a gelling agent selected from one or both of carrageenan and low methoxyl pectin, in which the gel filling is a thermally-reversible gel. Food comprising such gel fillings can be vegetarian or vegan and advantageously allow the re-solidification of the gelling agent following heating to reform the gel filling in the heated food.

  • Claim: 1. A food, comprising: an outer layer comprising a flour or dough; and a filling comprising a gel filling, wherein: the outer layer partially or completely surrounds the gel filling; the gel filling comprises a gelling agent, a cation, and water; the gelling agent comprises one or both of carrageenan and low methoxyl pectin; when the gelling agent comprises carrageenan, then the gel filling comprises the carrageenan at a concentration of at least 0.1 percent and no greater than 2 percent by mass; when the gelling agent comprises low methoxyl pectin, then the gel filling comprises the low methoxyl pectin at a concentration of at least 0.3 percent and no greater than 5 percent by mass; the gel filling comprises a liquid phase and a solid phase, in which the liquid phase is dispersed within the solid phase; the liquid phase comprises a majority of the water of the gel filling; the solid phase comprises a majority of the gelling agent of the gel filling; and the gel filling is a thermally-reversible gel because both (i) the gel filling can be heated to partition the gelling agent from the solid phase to the liquid phase such that the liquid phase is no longer dispersed within the solid phase, and (ii) the heated gel filling can then be cooled to partition the gelling agent from the liquid phase to the solid phase such that the liquid phase again becomes dispersed within the solid phase.
  • Claim: 2. The food of claim 1, wherein the gelling agent comprises carrageenan, and the gel filling comprises the carrageen at a concentration of at least 0.2 percent and no greater than 1 percent by mass.
  • Claim: 3. The food of claim 1, wherein the gelling agent comprises low methoxyl pectin, and the gel filling comprises the low methoxyl pectin at a concentration of at least 0.5 and no greater than 3 percent by mass.
  • Claim: 4. The food of claim 1, wherein the cation is calcium, and the gel filling comprises the calcium at a concentration of at least 200 parts per million and no greater than 0.15 percent by mass.
  • Claim: 5. The food of claim 1, wherein the cation is magnesium, and the gel filling comprises the magnesium at a concentration of at least 400 and no greater than 0.3 percent by mass.
  • Claim: 6. The food of claim 1, wherein the cation is potassium, and the gel filling comprises the potassium at a concentration of at least 400 and no greater than 0.3 percent by mass.
  • Claim: 7. The food of claim 1, wherein the gel filling comprises locust bean gum at a concentration of at least 500 parts per million and no greater than 0.6 percent by mass.
  • Claim: 8. The food of claim 1, wherein the filling comprises one or more solid food ingredients selected from fruits, vegetables, nuts, and meats.
  • Claim: 9. The food of claim 1, wherein the food is vegan because the food lacks any ingredient that is an animal product.
  • Claim: 10. The food of claim 1, wherein (i) the gel filling can be heated to a temperature of 100 degrees Celsius to partition the gelling agent from the solid phase to the liquid phase such that the liquid phase is no longer dispersed within the solid phase; (ii) the heated gel filling can then be cooled at a temperature of 21 degrees Celsius over a period of time to partition the gelling agent from the liquid phase to the solid phase such that the liquid phase again becomes dispersed within the solid phase; and the period of time is no greater than 15 minutes.
  • Claim: 11. A method to prepare a heated food for consumption, comprising: providing a food according to claim 1; heating the food to partition the gelling agent from the solid phase to the liquid phase such that the liquid phase is no longer dispersed within the solid phase; and cooling the heated food to partition the gelling agent from the liquid phase to the solid phase such that the liquid phase again becomes dispersed within the solid phase.
  • Claim: 12. The method of claim 11, wherein heating the food comprises: steaming the food; cooling the heated food comprises cooling the heated food at a temperature of at least 18 degrees Celsius and no greater than 27 degrees Celsius; the heated food is cooled over a period of time that is sufficient to partition the gelling agent from the liquid phase to the solid phase such that the liquid phase again becomes dispersed within the solid phase; and the period of time is no greater than 15 minutes.
  • Claim: 13. A method to prepare a food, comprising: dissolving a cation in an aqueous solution to produce a stock solution; dissolving a gelling agent in the stock solution to produce a gel solution, wherein the stock solution is maintained at a temperature of at least 35 degrees Celsius while the gelling agent is dissolved in the stock solution; cooling the gel solution to produce a gel filling; preparing a filling from the gel filling, wherein the filling comprises a portion of the gel filling and optionally one or more solid food ingredients; and covering the filling with an outer layer comprising a flour or dough to produce either the food or a manufacturing intermediate from which the food is prepared, wherein: the gelling agent comprises one or both of carrageenan and low methoxyl pectin; when the gelling agent comprises carrageenan, then the gelling agent is dissolved in the stock solution such that the gel filling comprises the carrageenan at a concentration of at least 0.1 percent and no greater than 2 percent by mass; when the gelling agent comprises low methoxyl pectin, then the gelling agent is dissolved in the stock solution such that the gel filling comprises the low methoxyl pectin at a concentration of at least 0.3 percent and no greater than 5 percent by mass; the method is performed such that the gel filling comprises a liquid phase and a solid phase, in which the liquid phase is dispersed within the solid phase; the method is performed such that the liquid phase comprises a majority of the water of the gel filling; the method is performed such that the solid phase comprises a majority of the gelling agent of the gel filling; and the method is performed such that the gel filling is a thermally-reversible gel because both (i) the gel filling can be heated to partition the gelling agent from the solid phase to the liquid phase such that the liquid phase is no longer dispersed within the solid phase, and (ii) the heated gel filling can then be cooled to partition the gelling agent from the liquid phase to the solid phase such that the liquid phase again becomes dispersed within the solid phase.
  • Claim: 14. The method of claim 13, wherein the gelling agent comprises carrageenan, and the gelling agent is dissolved in the stock solution such that the gel filling comprises the carrageen at a concentration of at least 0.2 percent and no greater than 1 percent by mass.
  • Claim: 15. The method of claim 13, wherein the gelling agent comprises low methoxyl pectin, and the gelling agent is dissolved in the stock solution such that the gel filling comprises the low methoxyl pectin at a concentration of at least 0.5 and no greater than 3 percent by mass.
  • Claim: 16. The method of claim 13, wherein the cation is calcium, and the cation is dissolved in the aqueous solution such that the gel filling comprises the calcium at a concentration of at least 200 parts per million and no greater than 0.15 percent by mass.
  • Claim: 17. The method of claim 13, wherein the cation is magnesium, and the cation is dissolved in the aqueous solution such that the gel filling comprises the magnesium at a concentration of at least 400 and no greater than 0.3 percent by mass.

  • Claim: 20. The method of claim 13, wherein the gel filling can be heated to a temperature of 100 degrees Celsius to partition the gelling agent from the solid phase to the liquid phase such that the liquid phase is no longer dispersed within the solid phase; (ii) the heated gel filling can then be cooled at a temperature of 21 degrees Celsius over a period of time to partition the gelling agent from the liquid phase to the solid phase such that the liquid phase again becomes dispersed within the solid phase; and the period of time is no greater than 15 minutes.
