Embodiment 1
[0041] 1) Purchase 50 kg of tilapia leftovers from tilapia fillets produced by the tilapia manufacturer, remove the viscera, blood stains and other inedible parts of the raw fish at an ambient temperature of 10°C, and wash them with 0°C ice water 2 times;
[0042] 2) Under the ambient temperature of 5-10°C, chop the raw materials into 3-4cm and 1-2cm wide pieces of broken fish bones;
[0043]3) Rinse the broken fish bones in dilute saline water for 3 times and drain the water. The mass ratio of the broken fish bones to dilute saline water is 1:4;
[0044] 4) At an ambient temperature of 5-10°C, use a wet-process ultrafine pulverizer to pulverize the fishbone pieces rinsed in the above step 3) into fishbone pulp, and the pulverization fineness is 60 mesh;
[0045] 5) Adjust the pH value of the fish bone pulp to 4.5 with a 5% lactic acid solution by mass fraction; at the same time, adjust the water mass content in the fish bone pulp to 85% by adding water;
[0046] 6) Divide t...
Embodiment 2
[0052] 1. Purchase 50 kg of red drum fish fillets left over from red drum fish fillets produced by the red drum fish manufacturer. Remove the viscera, blood stains and other inedible parts of the raw fish at an ambient temperature of 10°C and wash them with 0°C ice water. 2 times;
[0053] 2. Under the ambient temperature of 5-10°C, chop the raw materials into 3-4cm and 1-2cm wide pieces of broken fish bones;
[0054] 3. Rinse the broken fish bones in dilute saline water for 3 times and drain the water. The mass ratio of the broken fish bones to dilute saline water is 1:6;
[0055] 4) At an ambient temperature of 5-10°C, use a wet-process ultrafine pulverizer to pulverize the fish bone pieces rinsed in the above step 3) into a fish bone slurry with a pulverization fineness of 100 mesh;
[0056] 5) Adjust the pH of the fish bone slurry to 3.5 with a lactic acid solution with a mass fraction of 10%; at the same time, use a dehydrator to adjust the water mass content in the fish...
