PRODUÇÃO DE GELATINA EXTRAÍDA DE BEXIGA NATATÓRIA DE PEIXE: UMA REVISÃO NARRATIVA

Abstract

Global fish consumption has increased worldwide, primarily driven by consumers’ growing concern for healthy diets that provide high-quality protein. With the rising demand for fish, there has consequently been an expansion in industrial processing and in the volume of by-products generated, including skins, scales, bones, heads, and swim bladders. When improperly discarded, these residues may cause significant environmental impacts. For this reason, in recent years the scientific community has undertaken studies exploring the use of such by-products for gelatin extraction, demonstrating that these alternative sources are promising for application across multiple sectors, including the food, pharmaceutical, and biomedical industries.Accordingly, the present study aimed to conduct a narrative review of articles published between 2015 and 2024 addressing gelatin production from fish swim bladders. A total of eight articles were selected from the SCOPUS, PubMed, and Web of Science databases. The characterization of the extracted gelatin and the methodologies employed in the selected studies are presented herein.
