[0018] Example 1
[0019] A method for preparing chondroitin sulfate by ultra-high pressure micro-jet ultrafiltration, the steps are as follows:
[0020] 1. Pretreatment: Put the cartilage raw material into boiling water and boil it for 10 minutes, remove the fat and meat residue, air dry and crush, and pass through an 80 mesh sieve to obtain cartilage powder;
[0021] 2. Ultra-high pressure micro-jet lye extraction: Add 8% NaOH solution by volume to cartilage powder. The mass ratio of cartilage powder to NaOH solution is 1:60. Place the mixture of cartilage powder and NaOH solution at room temperature. The extraction is carried out in the ultra-high pressure micro-jet extractor, the pressure is 180MPa, the extraction time is 80min, and the filtrate obtained by filtration is extraction liquid one;
[0022] 3. Enzymatic hydrolysis: adjust the pH of the extract obtained in step 2 to 8 with hydrochloric acid, add trypsin according to the enzyme mass and solution volume ratio of 1.0:5000,...

[0027] Example 2
[0028] A method for preparing chondroitin sulfate by ultra-high pressure micro-jet ultrafiltration, the steps are as follows:
[0029] 1. Pretreatment: Put the cartilage raw material into boiling water and boil for 8 minutes, remove oil and meat residue, air dry and crush, and pass through a 60-mesh sieve to obtain cartilage powder;
[0030] 2. Ultra-high pressure micro-jet lye extraction: Add 4% NaOH solution in volume percentage to cartilage powder. The mass ratio of cartilage powder to NaOH solution is 1:50. Place the mixture of cartilage powder and NaOH solution at room temperature. The extraction is carried out in the ultra-high pressure micro-jet extractor, the pressure is 80MPa~120MPa, the extraction time is 30min~60min, and the filtrate obtained by filtration is extraction liquid one;
[0031] 3. Enzymatic hydrolysis: adjust the pH of the extract obtained in step 2 with hydrochloric acid to 5, add trypsin according to the enzyme mass and solution volume rati...
