Embodiment 1
[0027] A method for extracting collagen in fish skin by low-dose irradiation, comprising the following steps:
[0028] (1) Take fresh fish skin or fish skin leftovers after processing fish meat, wash it with water, and then grind it to make fish skin and meat;
[0029] (2) Soak the minced fish skin and meat in the deodorizing solution at 10 ℃ for 4 hours, rinse and dry to make fish skin dry powder. The deodorizing solution is preferably prepared by the following process: 10 g of astragalus, 8 g of Boil 4.5 g of ginger and 6 g of fennel seeds in 400 g of water, then filter, add 50 g of edible vinegar, 50 g of rice wine, and 12 g of honey to the filtrate and stir evenly;
[0030] (3) adding water to the dry fish skin powder and adjusting the pH value of the solution to 5.5 to prepare a fish skin material solution with a mass concentration of 45%;
[0031] (4) Transfer the fish skin material liquid into a transparent glass, add glyceride hydrolase and flavor enzyme, and then pla...
Embodiment 2
[0038] A method for extracting collagen in fish skin by low-dose irradiation, comprising the following steps:
[0039] (1) Take fresh fish skin or fish skin leftovers after processing fish meat, wash it with water, and then grind it to make fish skin and meat;
[0040] (2) Soak the minced fish skin and meat in the deodorizing solution at 20 °C for 5 hours, rinse and dry to make fish skin dry powder. The deodorizing solution is preferably prepared by the following process: 12.5 g of astragalus, 10 g of Boil 5 g of ginger and 7 g of fennel seeds in 450 g of water, then filter, add 65 g of edible vinegar, 65 g of rice wine, and 14 g of honey to the filtrate and stir evenly;
[0041] (3) adding water to the dry fish skin powder and adjusting the pH value of the solution to 6.5 to prepare a fish skin material solution with a mass concentration of 50%;
[0042] (4) Transfer the fish skin material liquid into a transparent glass, add glyceride hydrolase and flavor enzyme, and then pla...
Embodiment 3
[0049] A method for extracting collagen in fish skin by low-dose irradiation, comprising the following steps:
[0050] (1) Take fresh fish skin or fish skin leftovers after processing fish meat, wash it with water, and then grind it to make fish skin and meat;
[0051] (2) Soak the minced fish skin and meat in the deodorizing solution at 30 °C for 6 hours, rinse and dry to make fish skin dry powder. The deodorizing solution is preferably prepared by the following process: 15 g of astragalus, 12 g of Boil 5.5 g of ginger and 8 g of fennel seeds in 500 g of water, then filter, add 80 g of edible vinegar, 80 g of rice wine, and 16 g of honey to the filtrate and stir evenly;
[0052] (3) adding water to the dry fish skin powder and adjusting the pH value of the solution to 7.5 to prepare a fish skin material solution with a mass concentration of 55%;
[0053] (4) Transfer the fish skin material liquid into a transparent glass, add glyceride hydrolase and flavor enzyme, and then p...
