Description
Liquid nitrogen smoking freezes protein surfaces instantly while infusing smoke flavor, preserving texture and extending shelf‑life.
Technical
The technique relies on the rapid vaporization of liquid nitrogen at –196 °C, which absorbs 199 kJ kg⁻¹ of latent heat and super‑cools the food surface. This creates a sub‑zero environment that traps volatile smoke compounds within the matrix, reduces water activity below 0.3, and suppresses microbial growth while maintaining protein integrity.
