Embodiment 1

[0019] ⑴ Fish roe raw materials are removed and kneaded: fresh fish roe should be kept at 0-5°C during transportation. After the fish roe is removed, it is kneaded into granules. Be careful not to use too much force to prevent the fish roe from being crushed. Two times of kneading, 80%-90% of the first kneading, and the remaining 10%-20% of the second kneading, can improve the quality and yield of the finished product.

[0020] ⑵ Cleaning and sorting: Wash the kneaded fish roe at a water temperature of 0-3°C and sort to remove fine impurities.

[0021] (3) Ozone treatment: Use ozone water with a concentration of 3.0mg / L at 0-3°C to sterilize the treated fish roe for 8 minutes.

[0022] ⑷ Cleaning with ice water: After ozone disinfection treatment, wash the fish roe with ice water at 0-3 ℃ until the water is clean.

[0023] ⑸ Cold and fresh blending: Wash and drain the fish roe in ice water and transfer them to a freezer at -1.5-0°C, add compound seasoning liquid and soak fo...
