Embodiment 1
[0018] A preparation method of active probiotic gelatin sponge, comprising the following steps:
[0019] (1) At room temperature, take 37%~40% formaldehyde solution and add distilled water to make 10% formaldehyde solution;
[0020] (2) Take 8 parts by mass fraction of gelatin and add 120 parts by mass fraction of distilled water at 38°C, after fully dissolving, stir and foam to obtain a gelatin solution;
[0021] (3) Continue to stir the foamed gelatin solution, and add 10 parts by mass fraction of 10% formaldehyde solution while stirring to obtain a small and uniform gelatin foam;
[0022] (4) Take 2 parts of bacterial powder composed of lactic acid bacteria, bacillus, yeast or several active probiotics and add them to the gelatin foam while stirring to obtain a small and uniform active probiotic gelatin foam;
[0023] (5) Rapidly freeze-dry the obtained active probiotic gelatin foam at -20°C~-40°C to obtain active probiotic gelatin sponge;
[0024] (6) Cut the active prob...
