dc.description | World meat consumption reveals a clear preference for pork (36%) and beef (23%), which reveals
global dietary patterns. Meat quality depends largely on genetic factors such as breed, which will
determine tenderness, juiciness and flavor. Genetic crossbreeding can condition the texture and
composition of the meat derived, affecting lactic acid production and final pH. Before slaughter,
the desensitization of animals, either by means of electrical or compressed air systems, aims to
minimize animal stress and ensure humane treatment. These practices seek to maintain high
standards in the meat industry, where correct handling from the beginning to the maturation and
refrigeration phase is essential to avoid problems such as PSE and DFD meat, and to ensure
quality meat. In beef, a high pH (pH < 5.8) makes the meat tougher, while a pH of 5.5 improves
tenderness. On the other hand, in pork, a low pH (< 5.5) can facilitate the appearance of PSE
meats; but if the pH is medium (5.5-5.6), it improves tenderness and flavor. On the other hand,
temperature control at very low values (0-4°C) stimulates meat maturation, preserves flavor and
prevents denaturation of all proteins. Control of these parameters is essential to ensure the final
quality of the meat, preserving the freshness, texture and flavor desirable to consumers. | es_ES |

dc.description.abstract | El consumo mundial de carne revela una clara preferencia por las carnes de porcino (36%) y de
vacuno (23%), lo que pone de manifiesto patrones alimentarios globales. La calidad de la carne
depende en gran medida de factores genéticos como la raza, que determinará la terneza,
jugosidad y sabor los cruces genéticos puede condicionar la textura y la composición de la carne
derivada, afectando la producción de ácido láctico y el pH final. Antes del sacrificio, la
insensibilización de los animales, ya sea mediante sistemas eléctricos o por aire comprimido,
persigue minimizar el estrés animal y asegurar un trato humanitario. Estas prácticas procuran
mantener unos elevados estándares en la industria cárnica, donde el manejo correcto desde el
principio hasta la fase de maduración y refrigeración es primordial para evitar problemáticas como
la carne PSE y DFD, para asegurar una carne de calidad. En la carne de vacuno, un pH alto (pH
< 5,8) confiere un endurecimiento a la carne, mientras que un pH de 5,5 mejora la terneza. En
cambio, en la carne de porcino un pH bajo (< 5,5) puede facilitar la aparición de las carnes PSE;
pero si el pH es medio (5,5-5,6), mejora la terneza y el sabor. Por otro lado, el control de la
temperatura a unos valores muy bajos (0-4°C) estimula la maduración de la carne, conserva el
sabor y evita la desnaturalización de todas las proteínas. Es esencial el control de estos
parámetros para asegurar la calidad final de la carne, preservando la frescura, la textura y el
sabor deseables para los consumidores | es_ES |
