Embodiment 1

[0026] (1) Sprinkle ice and pack in the box: After the fresh large yellow croaker is fished out from the net cage, put it lightly in a polystyrene foam box with a thickness of 2.0cm and a size of 55cm×45cm×35cm (the size of the box). The large yellow croakers are stacked staggeredly on a layer of ozone ice, and the fish capacity accounts for 80% of the tank capacity, and the ice should be spread evenly, and the ice cannot be removed. Among them, the ozone content in the ozone ice is 5 mg / Kg, the particle size of the ozone ice is 0.3-0.5 cm, and the thickness of each layer of ozone ice is 1.2-1.5 cm.

[0027] (2) Washing with ice water: After the large yellow croaker is transported to the processing base, take the large yellow croaker out of the foam box and wash it with clean ice water at 0-1°C to remove the surface mucous membrane. When handling, the fish should be supported with both hands and handled with care.

[0032] (1) Sprinkle ice and pack in the box: After the fresh large yellow croaker is fished out from the net cage, put it lightly in a polystyrene foam box with a thickness of 2.0cm and a size of 55cm×45cm×35cm (the size of the box). The large yellow croakers are stacked staggeredly on a layer of ozone ice, and the fish capacity accounts for 90% of the tank capacity, and the ice should be spread evenly, and the ice cannot be removed. Among them, the ozone content in ozone ice is 8 mg / Kg, the particle size of ozone ice is 0.3-0.5 cm, and the thickness of each layer of ozone ice is 1.2-1.5 cm.

[0033] (2) Washing with ice water: After the large yellow croaker is transported to the processing base, take the large yellow croaker out of the foam box and wash it with clean ice water at 0-1°C to remove the surface mucous membrane. When handling, the fish should be supported with both hands and handled with care.

Abstract

The invention discloses a pseudosciaena crocea ice temperature fresh-keeping method, which comprises the steps of: ice spreading box loading, ice water cleaning, fluidized ozone ice pre-cooling, heat insulation box loading and ice temperature storage. The ozone ice and the fluidized ozone ice are sequentially adopted, the dual effects of lowering the fish body temperature and inhibiting the germ propagation are realized, further, the ice temperature storage is adopted, the freezing of the pseudosciaena crocea in the storage process is avoided, the original flavor and the fresh degree of the pseudosciaena crocea are more perfectly maintained, the quality guarantee period of the pseudosciaena crocea is greatly prolonged, and the pseudosciaena crocea is still fresh after being stored for 21 days.

Description

technical field [0001] The invention belongs to the field of processing aquatic products, and in particular relates to a method for keeping large yellow croaker fresh at ice temperature. Background technique [0002] Large yellow croaker belongs to the order Perciformes, and belongs to the family Scrotoaceae. It is commonly known as yellow croaker, also known as yellow croaker, big fresh, big yellow flower. one. It has a very important position in the ocean fishery in the western Pacific Ocean, and now it is one of the six famous and high-quality aquatic products that our country has a high reputation and competitiveness in the international market. It is also the largest seawater fish cultured in my country and one of the eight most advantageous export farmed aquatic products in China. Ningde, Fujian is the main production area of ​​large yellow croaker in my country, and its output accounts for more than 70% of the total amount of large yellow croaker in the country. ...
