The mean value of these five sensory properties was evaluated as overall acceptability. A trained panel using a Karlshrue-based scale divided into three degrees of deterioration and each degree with an associated sensory description evaluated the burgers (Wittig de Penna, 1981). The degrees go from one for the worst quality to three for the best quality. The panel consisted of 7–10 members from the Southern Regional Centre, INTI Mar del Plata/CIC.
