The mangrove crab (Ucides cordatus) is an important resource of mangroves which occurs in almost all in the Brazilian coast and it is notable for its considerable commercial value. The meat is usually wrapped in plastic wrap and its treatment is in a handmade way, in places where are not licensed by the Federal Inspection Service (SIF) and without the minimum hygienic control. In these places the animal’s death, done by hand, contributes to a possible contamination of the meat. In this experiment were analized 50 crabs purchased live in the outdoor market in Fortaleza, Ceara which were used during the six months of the experiment, two monthly samples. This work intends to benefit the crab meat according to Good Manufacturing Practices (GMP), using two other methods of processing: heat shock (CT) and electric shock to the system of restraint and killed by electric shock (SIAC). This machine paralyzes the animal with the application of electric pulses with controlled force and time. Thus it was evaluated the yields of meat extracted with both methods of slaughter and loss of weight due to cooking. The total average yield according to the method of slaughter, each month of the experiment, presented in percentage terms the following values respectively: CT - animal fresh weight 25.34, 23.28, 24.63, 25.38, 26, 29, 26.19% CT - 27.18 animal cooked weight, 24.81, 26.32, 26.99, 27.81, 27.74%, SIAC - animal fresh weight 26.56, 26.01 , 26.32, 25.77, 27.54, 26.97% and SIAC - animal cooked weight 28.35, 27.77, 27.69, 27.19, 28.95, 28.21%. In relation to average yields of meat extracted from the three segments pereiopod (PP), forceps or chelae (PQ) and carapace (C) separately crabs killed on the machine SIAC showed significant differences in yield of meat obtained from the segment PQ which may have favored its best performance in relation to slaughter CT, did not lose their legs during cooking which sometimes occurred with CT slaughter. Finally, the mean weight loss by cooking according to the methods of slaughter during the experiment showed similar, respectively CT - 6.68, 6.20, 6.32, 5.94, 5.38, 5.97% and SIAC - 5.26, 5.29, 4.97, 5.22, 4.91, 4.43% without no significant difference between the methods of slaughter, a phenomenon probably caused by the standardization process.
