Medical students and non-medical entrepreneurs, this might be a good business opportunity. Read to end.
In Fortaleza, Brazil, doctors faced a major problem — a shortage of human and pig skin for treating severe burns. Researchers at the José Frota Institute and the Federal University of Ceará (UFC) turned to an unexpected local resource: tilapia, one of Brazil’s most common fish.
When they examined tilapia skin, they found it contains large amounts of collagen types I and III, the same proteins in human skin that are vital for healing and tissue repair. Tilapia skin is strong, elastic, and readily available, making it ideal as a biological dressing.
How It’s Made Safe for Human Use
Cleaning and Scaling: Skins are washed, scaled, and defatted to remove all residues.
Chemical Disinfection: Soaked in chlorhexidine to eliminate bacteria, fungi, and viruses.
Glycerol Preservation: Immersed in sterilized glycerol for hours to preserve flexibility and disinfect deeper layers.
Sterile Packaging and Gamma Irradiation: Vacuum-sealed and sterilized using Cobalt-60 gamma rays to ensure complete microbial elimination.
After processing, the skin is odorless, infection-free, and can be stored for up to two years under refrigeration.
How It Works on Patients
When applied to burn wounds, the tilapia skin acts as a biological bandage that adheres naturally, forms a moist protective barrier, reduces pain, prevents infection, and speeds up healing by transferring collagen. It can stay in place for up to ten days, reducing the need for painful dressing changes.
Patients treated with tilapia skin reported faster recovery, less pain, and fewer scars. Because tilapia is cheap and abundant, this innovation offers a low-cost, effective burn treatment now gaining global attention.
