Example Embodiment
[0017] Example 1
[0018] 1. Decalcification of fish scales: (1) Removal of fish silver substances: Treat the fish scales with a tissue masher for 5 minutes to remove the fish silver substances indicated by the fish scales; (2) Acid decalcification: use hydrochloric acid to decalcify the fish scales. The liquid ratio is 1:20, the concentration of hydrochloric acid is 0.5 mol / L, and the decalcification time is 1 h; (3) Cleaning: remove the decalcification solution and wash the fish scales until neutral.
[0019] 2. Preheating of ultrasonic equipment: set the parameters of ultrasonic equipment, set the power of ultrasonic equipment to 200 W, set the temperature to 60 °C, start the equipment heating device, and preheat for 30-40 min to reach the temperature required for the reaction.
[0020] 3. Efficient preparation of fish scale gelatin: place the beaker containing the decalcified bighead carp scales and distilled water in the ultrasonic reactor, start the ultrasonic generating...
