(57) [Summary] [Purpose] To efficiently extract collagen from blowfish skin. [Structure] The skin of live blowfish is boiled down in an alcohol-containing aqueous solution having a deodorizing and sterilizing function like shochu in a boiling state to extract collagen, and the obtained collagen is stirred in water with vegetable gelatin and boiled. While preserving a corrosion inhibitor such as granular potassium sorbate for storage, add powdered agar to this boiling collagen solution, continue to boil and boil, then cool to semisolid. State. Cosmetics, fragrances for bath salts, and additives for foods are selectively blended with the corrosion inhibitor according to the use as collagen. |
