7. Deep processing technical procedures
7.1 Fish processing
- Fish processing shall comply with the requirements in Table 1.
- Table 1: Technical requirements for fish processing
- Stun and bleed: Use a head-strike method to stun and bleed live crispy-flesh tilapia.
- During bleeding, cut the gill arteries of the fish with a sharp knife on the operating table and immerse the fish in a running water bleeding tank, stirring occasionally to ensure that most blood drains out. The bleeding time should be controlled within 20–40 minutes.
- Scaling: Use high-pressure water, brush-roll equipment, or other methods to scale the fish. For areas where the pectoral fins are difficult to scale, manual scaling and individual inspection should be conducted. After scaling, rinse the fish with clean water.
- Disinfection: Disinfect the fish within 10 minutes at a water temperature below 10°C. After disinfection, rinse with clean water and proceed to the next process.
- Filleting: When filleting, wear disinfected gloves, cut accurately to avoid cuts or crumbles, and place the fillets on the conveyor belt promptly for trimming. Pay attention to the yield of finished products during filleting.
- Trimming: Remove fins, membranes, blood stains, residual organs, fish bones, or other parts that affect appearance and food safety from the fillets. After trimming, visually inspect and pay attention to the yield of finished products.
- Sorting: Separate unqualified fillets with visib
