A system for supercooling a product is provided, the system comprising: a chamber containing a supercooling medium; and disruptors that emit sound waves, ultrasound waves, and/or electromagnetic waves in the chamber; wherein during a cooling cycle the chamber reaches a cooling temperature below 0° C. and during a warming cycle the chamber reaches a warming temperature greater than the cooling temperature. The supercooling system may be used to supercool perishable products below freezing to extend shelf life and freshness of the products. Other embodiments of the supercooling system, and methods for its use, are described herein.
