The present research was developed in the laboratory of meat unas. The aims were to determine the capacity of water retention and the ph in fresh meat (cra), defrosted (crad), and cooked (crac), at different temperatures in the meat of beef, pork, chicken, sheep, rabbit and paco fish. as well as to produce sausage with the meat that has better water retention capacity and to evaluate the emulsion stability (ee) and capacity of water retention of the sausage (crae). We analyzed the capacity of water retention in fresh meat, defrosted and cooked (at 77, 82 and 87 °c). The data was expressed by the media ± sem, we used variance analyses of complete design at random (Dca) and the tukey test (p<0,05). The best capacity of water retention in fresh meat corresponded to paco fish cra i (25 %) and cra ii (17,333 %) and Ph (6,39), in defrosted meat corresponded to sheep crad (0,357 %) and ph ...
