Abstract
Perishable products, such as food products, can be preserved by cooling to temperatures below their freezing point without ice crystallization. In some embodiments, the perishable product is cooled to temperatures below the freezing point of water while a pulsed electric field and oscillating magnetic field are applied to the product. Apparatus for supercooling perishable products are also provided and include a pulsed electric field generator and an oscillating magnetic field generator.
Claims20
A method of preserving a perishable product in a container comprising the steps of:
- supercooling the perishable product by lowering the temperature to a temperature within the range of about 0° C. to about −20° C. while applying an oscillating magnetic field to the perishable product without applying a pulsed electric field;
- and
- maintaining the perishable product in the supercooled state while continuing to apply the oscillating magnetic field to the perishable product.
A method of preserving an organ in a supercooled state without freezing comprising cooling the organ to a temperature below 0° C. while applying an oscillating magnetic field without applying a pulsed electric field and subsequently maintaining the organ at the temperature while continuing to apply the oscillating magnetic field.
