An apparatus for providing a liquid-gas entrained cryogen mixture onto a food product includes a first pipe through which is provided a flow of liquid cryogen; a second pipe through which is provided a flow of gaseous cryogen, the second pipe in fluid communication with the first pipe at a mixing region; and a pulsing valve disposed at an interior of the second pipe upstream of the mixing region, the pulsing valve adapted for releasing the gaseous cryogen into the liquid cryogen at select intervals of time to provide a pulsating flow of the liquid-gas entrained cryogen mixture downstream of the mixing region for contacting the food product. A related method is also provided.
