[0017] First weigh 1000g of pigskin, put it in the refrigerator, freeze at -20°C for 10 hours, take it out after freezing, thaw at room temperature for 10 hours, cut the thawed pigskin into pieces, and cut the pieces according to the mass ratio of 1:10 Put the pigskin into 10% sodium hydroxide solution by mass fraction and soak for 30 hours, replace the sodium hydroxide solution every 8 hours, filter after soaking, and wash the filter residue with deionized water until the washing liquid is neutral. Put it in an oven and dry at 80°C for 5 hours to obtain a dried product; add the above dried product to anhydrous ether at a mass ratio of 1:5, soak for 10 hours and then filter to collect the filter residue, and then collect it at a mass ratio of 1:5 Add the filter residue in n-butanol and soak for 12h, take out the filter residue after soaking, and wash it 5 times with deionized water, press the mass ratio of 1:20, add the filter residue after washing in 10% acetic acid solution b...
