The limitations of fish gelatin (FG) in terms of weak gelling properties, low gel strength, and inability to set at room temperature. By investigating the impact of furcellaran (FUR), a gelling agent, the study offers a solution to enhance FG’s functional properties, making it a more viable alternative to traditional animal-based gelatin. The findings suggest that FUR improves the texture, gel strength, and thermal stability of FG, which is crucial for a wide range of applications in the food and pharmaceutical industries. This could lead to the development of more sustainable, plant-based gelling agents, offering ethical and environmental benefits. Additionally, the study enhances the understanding of the molecular interactions between FG and FUR, providing a foundation for further innovations in gelation technology and the creation of improved, multifunctional gel-based products.
