Prevention of Pale, Soft, Exudative Porcine Muscle Through Partial Freezing with Liquid Nitrogen Post‐Mortem a

SUMMARY Liquid nitrogen (L‐N 2 ) treatment over a wide range of immersion rates was studied to determine the effectiveness of this treatment in controlling the development of pale, soft, exudative muscle as well as improving other muscle properties. The L‐N 2 treatment was extremely effective in preventing the development of pale, soft, exudative muscle regardless of whether subsequent equilibration was at ‐18 or 4°C. Most of the immersion periods lowered physiological conditions at the onset of rigor, and only the severe immersion rates showed evidence of thaw rigor.
