Özet

The increasing demand for sustainable seafood products has driven research into innovativeapproaches for utilizing fish processing by-products. This study investigates the potential of microbialtransglutaminase (MTGase) in producing restructured fish fillets from processing residues. Fillets wereprepared by collecting and refining fish processing by-products, adjusting enzyme concentrations, andapplying optimized processing techniques. Three sample groups were analyzed for their texturalproperties: a control group (without enzyme), 4% MTGase treatment, and 7% MTGase treatment.The results demonstrated significant improvements in cohesiveness, hardness, and elasticity in MTGase-treated samples compared to the control, emphasizing the enzyme’s effectiveness in restructuring fishprotein matrices. These findings highlight MTGase as a promising tool for enhancing the texture andfunctionality of seafood by-products, contributing to sustainable and value-added seafood production The increasing demand for sustainable seafood products has driven research into innovative approaches for utilizing fish processing by-products.
