Embodiment 1
[0033] 1. Preparation of fish-derived collagen antioxidant peptides:
[0034] 1) Pre-treatment: Clean the fish scale raw material, soak it in 0.1mol / L NaOH solution with a mass ratio of material to liquid of 1:20, rinse it with tap water until the pH is neutral (about 10 times), and then rinse it with distilled water for 3 times ;
[0035] 2) Decalcification: Soak fish scale raw materials in 0.4mol / L HCl solution with a material-to-liquid mass ratio of 1:20, stir with a magnetic stirrer for 90 minutes, rinse with tap water until the pH is neutral (about 10 times), and then use Rinse with distilled water 3 times;
[0036] 3) Boil in water: add fish scale or fish bone raw material and water with a mass ratio of 1:1 to the high-pressure dipping tank on the instantaneous pressure-changing extraction tank, and pressurize the high-pressure dipping tank by 8-10kgf / cm through the air pump 2 , soak for 2 hours; put the material in the high-pressure dipping tank into the low-pressure ...
Embodiment 2
[0050] 1. Preparation of fish-derived collagen antioxidant peptides:
[0051] 1) Pre-treatment: Clean the fish bone raw material, soak it in 0.1mol / L NaOH solution with a mass ratio of material to liquid of 1:20, rinse it with tap water until the pH is neutral (about 10 times), and then rinse it with distilled water for 3 all over;
[0052] 2) Decalcification: Soak fishbone raw materials in 0.5mol / L EDTA solution with a material-to-liquid mass ratio of 1:5 for 5 days, adjust the pH to 7.0-7.8 with NaOH, replace the EDTA solution every 24 hours, and rinse with tap water pH to neutral (rinse about 10 times), then rinse with distilled water 3 times, then soak for 24 hours in 10% isopropanol solution with a mass ratio of material to liquid of 1:20, and then rinse with tap water to neutral pH (rinse About 10 times), then rinse with distilled water 3 times;
[0053] 3) Poaching: Add water with a mass ratio of 1:2 between fishbone raw material and liquid to liquid into the high-pre...
Embodiment 3
[0066] 1. Preparation of fish-derived collagen antioxidant peptides:
[0067] 1) Pre-treatment: Clean the fish scale raw material, soak it in 0.1mol / L NaOH solution with a mass ratio of material to liquid of 1:20, rinse it with tap water until the pH is neutral (about 10 times), and then rinse it with distilled water for 3 times ;
[0068] 2) Decalcification: The fish scale raw material is soaked in a 0.4mol / L HCl solution with a mass ratio of material to liquid of 1:20, and at the same time stirred with a magnetic stirrer for 90 minutes, then rinsed with tap water to neutral pH (rinsed about 10 times), and then used Rinse with distilled water 3 times;
[0069] 3) Boil in water: Add water with a ratio of 1:1.5 of fish scale raw material to liquid to liquid into the high-pressure dipping tank on the instantaneous pressure-changing extraction tank, and pressurize the high-pressure dipping tank by 8-10kgf / cm through the air pump 2 , soaked for 1.5 hours; put the material in the...
