Embodiment 1
[0038] Weigh 1000 parts of dry collagen and add it to 8000 parts of water. After swelling for 50 minutes at room temperature, it is placed in a water bath at about 50°C and continuously stirred for about 40 minutes to obtain a collagen solution with a mass fraction of approximately 11.11%. At the same time, weigh 10 parts of modifier (3 parts dialdehyde starch with 90% aldehyde group content and 7 parts dialdehyde methyl cellulose with 74% aldehyde group content) and add it to 990 parts of water at around 25℃. Stir for about 8 hours to obtain a modifier solution with a mass fraction of about 1%. At 40℃, blend in the ratio of modifier to collagen dry weight ratio of 1:100, and keep stirring for about 30 minutes to obtain a modified collagen stock solution with a concentration of about 10% based on the dry collagen weight. . Add plasticizer to the original solution of modified collagen according to the ratio of plasticizer (blended at a ratio of propylene glycol to xylitol dry w...
Embodiment 2
[0040] Weigh 2000 parts of dry collagen and add it to 97500 parts of water. After swelling for 30 minutes at room temperature, it is placed in a water bath at about 40°C and continuously stirred for about 30 minutes to obtain a collagen solution with a mass fraction of about 2.01%. Weigh 10 parts of modifier (2 parts of dialdehyde starch with 90% aldehyde group, 5 parts of dialdehyde cellulose with 87% aldehyde group, and dialdehyde ethyl cellulose with 82% aldehyde group 3 parts) was added to 490 parts of water, and continuously stirred at about 25°C for about 12 hours to obtain a modifier solution with a mass fraction of about 2%. At 50°C, blend in a ratio of modifier to collagen dry weight ratio of 1:200, and keep stirring for about 45 minutes to obtain a modified collagen stock solution with a concentration of about 2% based on the dry collagen weight. . Add the plasticizer to the original solution of modified collagen at a ratio of plasticizer (blended at a 2:1 ratio of f...
Embodiment 3
[0042] Weigh 1500 parts of dry collagen and add it to 46500 parts of water. After swelling at room temperature for 35 minutes, place it in a water bath at about 50°C and continuously stir for about 30 minutes to obtain a collagen solution with a mass fraction of about 3.125%. Weigh 30 parts of modifier (7 parts dialdehyde starch with 90% aldehyde group content, 9 parts dialdehyde cellulose with 85% aldehyde group content, 14 parts dialdehyde sodium alginate with 83% aldehyde group content ) Adding to 1970 parts of water, stirring continuously for about 10 hours at 25°C, to obtain a modifier solution with a mass fraction of about 1.5%. At 40°C, blend in a ratio of 1:50 between modifier and collagen by dry weight. Stir continuously for about 45 minutes to obtain a modified collagen stock solution with a concentration of about 3% based on the weight of dry collagen. . Add plasticizer to the original solution of modified collagen according to the ratio of plasticizer (blended at a...
