Problems solved by technology

Our country is relatively backward in the color development technology of fish fillets. Usually, the finished fish fillets are placed in plastic bags, and then filled with a large amount of carbon monoxide gas. On the one hand, this operation method is not conducive to the safety of the operator. The operation process must go through two-step sterilization, and the amount of carbon monoxide is large, the color of the fish fillets is uneven, and it is easy to be infected with microorganisms again, which affects the export of products. The cost of using foreign technology is too high. Therefore, it is an urgent problem to study the color development technology suitable for the processing of tilapia fillets in my country

Embodiment 1

[0017] Fill the tank with water, adjust the temperature of the tank to be basically the same as the temperature of the aquaculture water environment, put the tilapia in the tank, put the fish and water into the tank at a weight ratio of 1:3, and keep it for 5 minutes; first put carbon monoxide gas into the tank , the rate of carbon monoxide and air per liter of water is 1.5mL / min, the gas introduced is mixed by the air-water mixing pump, the ventilation time is 10min, and then the air is changed to 3min, and the ventilation volume requires the same carbon dioxide. After the ventilation is finished, the tilapia is taken out, sliced ​​and sterilized to make colored tilapia fillets.

Embodiment 2

[0019] Fill the tank with water, adjust the temperature of the tank to be basically the same as the temperature of the aquaculture water environment, put the tilapia in the tank, put the fish water into the tank with a weight ratio of 1:2.5, and keep it for 3 minutes; first pass carbon monoxide gas into the tank , the rate of carbon monoxide and air per liter of water is 1.25mL / min, the gas introduced is mixed by the air-water mixing pump, the ventilation time is 12min, and then the air is changed to 5min, and the ventilation volume requires the same carbon dioxide. After the ventilation is finished, the tilapia is taken out, sliced ​​and sterilized to make colored tilapia fillets.

Embodiment 3

[0021] Fill the tank with water, adjust the temperature of the tank to be basically the same as the temperature of the aquaculture water environment, put the tilapia in the tank, put the fish and water into the tank at a weight ratio of 1:3, and keep it for 5 minutes; first put carbon monoxide gas into the tank , the rate of carbon monoxide and air per liter of water is 1.0mL / min, the gas introduced is mixed by the air-water mixing pump, the ventilation time is 15min, and then the air is changed to 5min, and the ventilation volume requires the same carbon dioxide. After the ventilation is finished, the tilapia is taken out, sliced ​​and sterilized to make colored tilapia fillets.

Abstract

The tilapia fillet coloring process includes the following steps: filling water into water trough, regulating the water temperature to basically the same as that in cultivating environment, and setting tilapia inside the water trough; introducing CO and air successively through a gas-water mixing pump to mix homogeneously for 13-20 min; and cutting tilapia, sterilizing and making tilapia fillet. The said coloring process adopts live body coloring technology, and has reduced excessive CO gas on the worker, decreased sterilizing times, and raised coloring effect.

Description

technical field [0001] The invention relates to a color development method in the process of processing fish fillets, in particular to the application of the color development technology in the processing of tilapia fillets. Background technique [0002] In recent years, my country's tilapia industry has developed rapidly, and has formed a good breeding and processing production system, becoming a highly competitive aquatic product with international competitiveness. According to statistics, in 2004, the output of tilapia in my country reached 897,000 tons, ranking first in the world, and the export volume reached 87,000 tons. The global consumption of tilapia is on the rise and it is gaining popularity internationally. According to the statistical data analysis of the United States Department of Agriculture, the import volume of frozen tilapia fillets accounts for about 32% of the total import volume of tilapia products in the United States, and the market share of tilapia...
