A sponge protein hydrolysate is produced using sponge skeleton fibers (sponginnfibers) refined from sponges as the raw material, by carrying out hydrolysis using annacidic solution, in which the pH is adjusted to 1 using an electrolytic acidic water with anpH of less than 2.5 and oxidation-reduction potential of more than 1,000 mV mixednwith an acid, to reduce the molecular weight of sponge proteins to less than 5,000. |
