1. the preparation method of a fish gelatin macromolecular material is characterized in that comprising the following steps:

  • 1) raw materials pretreatment;

    take fish-skin, fish scale as raw material, soak with the sodium hydroxide solution that contains tensio-active agent and oxygenant, then rinsing is clean, adds pure water, with polycarboxylic acid, the pH of solution is adjusted to 5~

    6, then blends into the extraction raw material of gelatin;

    2) add proteinase inhibitor and protein thermal denaturation protective material in the raw material that the extraction of gelatin;

    in step

         1) pre-treatment is good, heat up and extract gelatin solution;

    3) gelatin solution that drying;

    with step

         2) obtains adopts and filters impurity such as removing melanochrome, and cooled and solidified is pulverized after cryodrying, is prepared into fish gelatin macromolecule material powder.
