Embodiment 1

[0016] A kind of humane slaughtering and processing method that can improve the eating quality of tilapia fillets is as follows: 1) Temporary cultivation: fresh and alive tilapias are put into temporary cultivation ponds for temporary cultivation, and the weight ratio of water and fish in the temporary cultivation ponds is not low At 3:1, the water temperature does not exceed 25°C, and the compressed air or oxygen is continuously fed into the holding tank; and the generated foam is removed in time, and the holding time is not less than 3 hours; 2) Carbon dioxide suffocation: after the holding is over , stop feeding compressed air or oxygen into the holding pool, and instead feed carbon dioxide gas. The flow rate of carbon dioxide gas per 100 liters of water is controlled at 5 liters per minute, and the continuous feeding time is 10 minutes. After the ventilation is over, Luo Fei When the fish is in a comatose state with its abdomen facing up and its tail can only swing slightly...

Embodiment 2

[0018] A kind of humane slaughtering and processing method that can improve the eating quality of tilapia fillets is as follows: 1) Temporary cultivation: fresh and alive tilapias are put into temporary cultivation ponds for temporary cultivation, and the weight ratio of water and fish in the temporary cultivation ponds is not low At 3:1, the water temperature does not exceed 25°C, and the compressed air or oxygen is continuously fed into the holding tank; and the generated foam is removed in time, and the holding time is not less than 3 hours; 2) Carbon dioxide suffocation: after the holding is over , stop feeding compressed air or oxygen into the holding pool, and instead feed carbon dioxide gas. The flow rate of carbon dioxide gas per 100 liters of water is controlled at 50 liters per minute, and the continuous feeding time is 2 minutes. After the ventilation is over, Luo Fei When the fish is in a comatose state with its abdomen facing up and its tail can only swing slightly...

Abstract

The invention discloses a slaughtering and processing method capable of improving the edible quality of a tilapia mossambica fillet. The humanistic slaughtering and processing method comprises the following steps: temporarily fostering the alive tilapia mossambica; introducing carbon dioxide into a temporary fostering pond, so that the tilapia mossambica is chokey and narcose; slantwise cutting the bottom abdomen between two gills and a tilapia mossambica body to the heart in one step; and putting the tilapia mossambica into cold water to bleed. The invention has the advantages that the humanistic slaughtering and processing method of the temporarily-fostered alive tilapia mossambica comprises the following steps: leading the tilapia mossambica to be chokey by the carbon dioxide; and slaughtering, bleeding and cooling, wherein the whole slaughtering procedure is operated under a moderate status, the intense stress reaction of the tilapia mossambica can be avoided, the glycolysis speedof the sugar in the muscular tissue of the tilapia mossambica can be reduced, and the phenomena such as the fast reduction of the PH value of the tilapia mossambica, the fast degradation of the nucleotide and the like can be avoided, so that the edible quality of the tilapia mossambica fillet is improved, and the quality guarantee period of the tilapia mossambica fillet is prolonged.

Description

technical field [0001] The invention belongs to the technical field of aquatic product processing. Specifically, it is a slaughtering and processing method that can improve the eating quality of tilapia fillets. Background technique [0002] my country is the largest tilapia breeding and processing country in the world. At present, the slaughtering method of tilapia in my country is mainly to pick up the tilapia after temporary breeding, press the head tightly, and then kill the tilapia on the bottom between the gills and the body of the fish on both sides. The method of directly slaughtering and bleeding by inserting a knife in the abdomen to the heart, and then putting it into the water, the tilapia struggled fiercely during the whole slaughter process, resulting in the rapid fermentation of sugar in the body and the production of a large amount of lactic acid, which caused the pH value of the fish to drop rapidly; The adenosine triphosphate in the fish is also rapidly degr...
