Embodiment 1
[0023] A method for degrading histamine in aquatic products, comprising the following steps:
[0024] a) Clean the fresh tuna and cut it into pieces, and keep it fresh at low temperature; use an automatic fish washing machine with a water temperature of 4-10°C, automatically spray the conveyor belt with tap water, and pick out miscellaneous fish and sundries at the same time, and clean the fish body Less than 10,000 bacteria;
[0025] b) Immerse the cleaned tuna fish pieces in the treatment solution, and then pass through the ozone and then vibrate ultrasonically. The concentration of ozone is 2.5ppm, the temperature of the treatment solution is 0°C, and the treatment time is 40min; take it out, drain it and put it in an insulating bag, and carry out The high-voltage pulsed electric field was treated for 35 minutes, the pulse time of the high-voltage pulsed electric field was 1s, the pulse frequency was 55Hz, and the electric field strength was 45kV / cm; the treatment solution ...

[0028] A method for degrading histamine in aquatic products, comprising the following steps:
[0029] a) Clean the fresh skipjack tuna and cut it into pieces, and keep it fresh at low temperature; use an automatic fish washing machine with a water temperature of 4-10°C, automatically spray the conveyor belt with tap water, and pick out miscellaneous fish and sundries at the same time, and clean the fish The total number of bacteria is less than 10,000;
[0030] b) Immerse the cleaned bonito pieces in the treatment solution, and pass through the ozone and then ultrasonically vibrate. The concentration of ozone is 3.2ppm, the temperature of the treatment solution is 2°C, and the treatment time is 50min; take it out, drain it and put it in an insulating bag. Carry out the high-voltage pulsed electric field treatment for 45min, the pulse time of the high-voltage pulsed electric field treatment is 1s, the pulse frequency is 64Hz, and the electric field strength is 48kV / cm; 28 part...
Embodiment 3
[0033]A method for degrading histamine in aquatic products, comprising the following steps:
[0034] a) Clean the fresh mackerel and cut it into pieces, and keep it fresh at low temperature; use an automatic fish washing machine with a water temperature of 4-10°C, automatically spray the conveyor belt with tap water, and pick out miscellaneous fish and sundries at the same time, and clean the fish The total number of bacteria is less than 10,000;
[0035] b) Immerse the cleaned mackerel fish pieces in the treatment solution, and pass through the ozone and then ultrasonically vibrate. The concentration of ozone is 4ppm, the temperature of the treatment solution is 5°C, and the treatment time is 60min; after taking it out, drain it and put it into an insulating bag, and carry out The high-voltage pulsed electric field was treated for 50 minutes, the pulse time of the high-voltage pulsed electric field was 1s, the pulse frequency was 75Hz, and the electric field strength was 55kV...
