Packaged frozen food, method for thawing packaged frozen food, method for manufacturing packaged frozen food, and packaging container

Abstract

This invention provides packaged frozen foods suitable for heating and thawing, even for frozen foods where the preferred degree of heating varies depending on the part of the food, as well as a method for thawing packaged frozen foods, a method for manufacturing packaged frozen foods, and a packaging container. [Solution] The packaged frozen food according to the present invention is a packaged frozen food that is heated and thawed before being consumed, and comprises a first portion that requires heating during thawing and a second portion that requires heating to a lower degree than the first portion or does not require heating at all, and a cold storage agent installed corresponding to the second portion, which is capable of absorbing and / or reflecting microwaves and is a cooled liquid composition and / or gel composition.

Claims

1. A frozen food having a first portion that requires heating during heating and thawing, and a second portion that requires heating to a lower degree than the first portion or does not require heating at all, A packaged frozen food that is heated and thawed for consumption, comprising a coolant containing a cooled liquid composition and / or gel composition, which is installed in correspondence with the second part and is capable of absorbing and / or reflecting microwaves.

2. The packaged frozen food according to claim 1, wherein the cold storage agent is solidified.

3. The packaged frozen food according to claim 1, wherein the cold storage agent contains water.

4. Furthermore, it has a food carrier that supports the frozen food, The frozen food is arranged such that the second portion is in contact with a part of the food carrier. The packaged frozen food according to claim 1, wherein the cold storage agent is arranged in contact with the surface opposite to the portion of the food carrier that the second portion of the food carrier is in contact with.

5. Furthermore, the packaged frozen food according to claim 4, further comprising a cold storage agent carrier for supporting the cold storage agent, wherein the cold storage agent is disposed between the food carrier and the cold storage agent carrier.

6. The packaged frozen food according to claim 4, wherein the food carrier has a food carrier portion that has a recess capable of carrying the frozen food and a convex portion that is in the direction opposite to the frozen food.

7. Furthermore, it has a cold storage agent carrier for supporting the cold storage agent, The packaged frozen food according to claim 6, wherein the cold storage agent carrier has a recess in a portion corresponding to the protrusion of the food carrier.

8. The packaged frozen food according to claim 1, wherein the frozen food is frozen sushi.

9. A method for thawing a packaged frozen food, comprising heating the packaged frozen food according to any one of claims 1 to 8.

10. A method for manufacturing packaged frozen food, comprising simultaneously cooling a pre-freezing food having a first portion that requires heating when frozen and a second portion that requires heating to a lower degree than the first portion or does not require heating, and a refrigerant, which is a liquid composition and / or gel composition installed corresponding to the second portion and capable of absorbing and / or reflecting microwaves.

11. A packaging container for packaging frozen food that is to be heated and thawed before consumption, and which has a first portion that requires heating and a second portion that requires a lower degree of heating than the first portion or does not require heating, A food carrier having a food carrier portion for supporting the frozen food, It comprises a coolant carrier that carries a coolant obtained by cooling a liquid composition and / or a gel composition, The food carrier is configured such that the second portion of the frozen food comes into contact with the food carrier portion. The cold storage agent carrier is configured such that the cold storage agent comes into contact with the food carrier from the side opposite to the frozen food, in a packaging container.

12. The packaging container according to claim 11, wherein the food carrier has a food carrier portion that has a recess so as to be able to carry the frozen food, and a convex portion that is formed in the direction opposite to the frozen food.

13. The packaging container according to claim 12, wherein the cold storage agent carrier has a recess serving as a cold storage agent carrier in a portion corresponding to the protrusion of the food carrier.
