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

Example Embodiment

[0016] Example 1

[0017] Fill the tank with water, adjust the temperature of the tank to be basically the same as the temperature of the culture water environment, put the tilapia into the tank, put the fish water in a weight ratio of 1:3, and temporarily raise it for 5 minutes; first pass the carbon monoxide gas into the tank , The carbon monoxide and air flow rate per liter of water is 1.5mL / min, the gas is mixed by a gas-water mixing pump, the ventilation time is 10 minutes, and the air is changed to 3 minutes. The ventilation volume requires the same carbon oxide. After the aeration, the tilapia is taken out, cut into pieces, and sterilized to make colored tilapia fillets.

Example Embodiment

[0018] Example 2

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

Example Embodiment

[0020] Example 3

[0021] Fill the tank with water, adjust the temperature of the tank to be basically the same as the temperature of the culture water environment, put the tilapia into the tank, put the fish water in a weight ratio of 1:3, and temporarily raise it for 5 minutes; first pass the carbon monoxide gas into the tank , The carbon monoxide and air flow rate per liter of water is 1.0mL / min, the gas is mixed by a gas-water mixing pump, the ventilation time is 15 minutes, and the air is changed to 5 minutes. The ventilation volume requires the same carbon oxide. After the aeration, the tilapia is taken out, cut into pieces, 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...
