Embodiment Construction
[0010] Take 1000g of commercially available hemp stingers pickled with three alums, drain, soak in 2-5 times the amount of deionized water, and change the water every 2-3 hours until the content of sodium chloride in the soaking water is lower than 1.5 Up to ppm (chloride ion test was negative). The soaked desalted jellyfish adjusts the pH to 5.8-6.8 (the optimum pH of a special composite collagenase), and digests it at 38-40°C (the optimum temperature of the collagenase) for 12-16 hours to obtain a clarified The transparent liquid is the hydrolyzed collagen solution; the hydrolyzed collagen solution is freeze-dried to obtain 20 g of hydrolyzed collagen powder solid with a purity of more than 95% and peptides with a molecular weight below 3000 accounting for more than 85%.
