Embodiment 1
[0027] A preparation method for tuna bone powder, comprising the steps of:
[0028] (1) Raw material pretreatment: select tuna bone raw materials with bright white color and no peculiar smell, rinse them repeatedly under drinking water, drain and set aside;
[0029] (2) Softening of fish bones: The washed tuna bones are treated with subcritical water combined with microwave, and the fish bones are soaked in subcritical water at 110°C for 10 minutes. The fish bones and subcritical water are mixed according to the ratio of material to liquid at 1:5. Then dry it at 70°C, and then treat it with 550w ultrasonic wave for 1.2min to obtain softened fish bones for later use;
[0030] (3) Deodorization of fish bones: mix the softened fish bones with 6.7% deodorization agent by mass evenly, let it stand for 20 minutes, rinse it with running water 4 times after the end, and get the deodorization fish bones for use (the deodorization agent is prepared as follows Preparation method: accord...
Embodiment 2
[0035] A preparation method for tuna bone powder, comprising the steps of:
[0036] (1) Raw material pretreatment: select tuna bone raw materials with bright white color and no peculiar smell, rinse them repeatedly under drinking water, drain and set aside;
[0037] (2) Fish bone softening: The washed tuna bone is treated with subcritical water combined with microwave, and the fish bone is soaked in subcritical water at 100°C for 10 minutes. The fish bone and subcritical water are mixed according to the ratio of material to liquid at 1:4. Then dry at 60°C, and then supplemented with 500w ultrasonic treatment for 2.0min, to obtain softened fish bones for later use;
[0038] (3) Deodorization of fish bones: Mix the softened fish bones with 10.0% deodorization agent by mass evenly, let it stand for 10 minutes, rinse with running water 3 times after the end, and get the deodorization fish bones for use (the deodorization agent is prepared as follows The method is prepared: accord...
Embodiment 3
[0043] A preparation method for tuna bone powder, comprising the steps of:
[0044] (1) Raw material pretreatment: select tuna bone raw materials with bright white color and no peculiar smell, rinse them repeatedly under drinking water, drain and set aside;
[0045] (2) Softening of fish bones: The washed tuna bones are treated with subcritical water combined with microwave, and the fish bones are soaked in subcritical water at 120°C for 30 minutes. The fish bones and subcritical water are mixed according to the material-to-liquid ratio of 1:6. Then dry at 80°C, and then use 600w ultrasonic treatment for 0.5min to soften the fish bones for later use;
[0046] (3) Deodorization of fish bones: Mix the softened fish bones with 10.0% deodorization agent by mass evenly, let it stand for 10 minutes, rinse it with running water 5 times after the end, and get the deodorization fish bones for use (the deodorization agent is prepared as follows Preparation method: according to the prop...
