Abstract
A method of preserving food in a supercooled state, wherein food is packed inside a container with no head space, and then converted to a supercooled state by a cooling step in which the food is cooled from a temperature higher than the freezing point to a temperature below the freezing point at a cooling rate exceeding −0.5° C./h but no more than −5.0° C./h.
Claims4
A method of preserving food in a supercooled state comprising:
- filling food in a container to a level to form a fill level in the container, and transversely sealing the food-containing container beneath the food fill level so that the food is sealed in the container with no head space;
- and then
- converting the food, sealed in the container, to a supercooled state by cooling said food in said sealed container, containing no head space, from a temperature higher than the freezing point of the food to a temperature below the freezing point of the food at a cooling rate exceeding 0.5° C./h, but no more than 5.0° C./h,
- said supercooling state being achieved without the application of pressure.

A method of preserving food in a frozen state comprising:
- filling food in a container to a level to form a fill level in the container, and transversely sealing the food-containing container beneath the food fill level so that the food is sealed in the container with no head space
- converting the food, sealed in the container, to a supercooled state by cooling said food in the sealed container, containing no head space, from a temperature higher than the freezing point of the food to a temperature below the freezing point of the food at a cooling rate exceeding 0.5° C./h, but no more than 5.0° C./h;
- said supercooled state being achieved without the application of pressure;
- and then
- converting the supercooled food in said supercooled state to a frozen state by disturbing said supercooled state of the food in the sealed container, said supercooled state being achieved without the application of pressure.
