Summary: | The invention discloses a preparation method of anti-crosslinking gelatin, which comprises the following steps: S1, selecting a gelatin extraction raw material, carrying out fragmentation treatment, and washing with water; S2, soaking the raw materials in an acid solution with the pH value of 0.8-3 or an alkali solution with the pH value of 11-13; S3, washing the raw materials with water, the acid solution or the alkali solution in sequence, and neutralizing the raw materials until the pH value is 6.5-8.0; S4, extracting gelatin: adding the raw materials into a gelatin extraction pot, adding 50-80 DEG C warm water to immerse the raw materials, boiling out the raw materials until the concentration of a gelatin solution reaches 2-5%, and extracting the gelatin solution for 6 times; S5, taking 40-60% of the gelatin solution in S4, adding the acid solution or the alkali solution to control the pH value to be 1-3 or 11-13, soaking, neutralizing, washing with water, filtering with an ultrafiltration membrane to obt |
