The use of high hydrostatic pressure (HHP) on fresh beef causes a deleterious effect on red colour. A beef product
subjected to HHP exhibiting acceptable colour and microbiological stability was developed; the process requires
as a first step the immersion in a preservative solution containing ascorbic acid, sodium nitrite, and sodium
chloride. Desirability functions were used to optimise the composition of this solution in order to maintain the
colour attributes minimising the concentration of sodiumnitrite. The productwas packed in lowgas permeability
film before HHP treatment. The effect of the applied pressure (300, 600 MPa) on quality parameters (colour,
texture) was analysed. The stability of the product during storage at 4 °C was determined by microbial counts,
colour, texture, and exudate. The combination of treatments provided acceptable colour and microbiological
stability during four and six weeks of refrigerated storage after the product has been subjected to 300 and
600 MPa, respectively.
