[8] Birdseye's original cryogenic freezing approach using immersion in liquid nitrogen is still ...

The short freezing prevents formation of large ice crystals in the product's cells, which destroys the membrane structures at the molecular level. [2] [3] This makes the product keep its shape, colour, smell and taste after defrost, to a far greater extent.
