Special Issue Information

Dear Colleagues,

Seafood flavor, freshness, and nutritional value are critical factors that shape consumer preferences and market competitiveness. This Special Issue, titled “Advanced Innovations in Seafood Processing, Preservation, and Bioactive Compounds”, focuses on recent breakthroughs that enhance the sensory, nutritional, and functional qualities of aquatic products. Emphasis is placed on novel processing and preservation technologies, such as high-pressure treatment, pulsed electric fields, and cold plasma, which maintain delicate flavor profiles and inhibit spoilage. Advances in enzymatic hydrolysis and fermentation have also been explored for generating marine-derived bioactive peptides and flavor-active compounds that contribute to umami and aroma enhancement. In addition, intelligent packaging systems and natural antioxidants or antimicrobial agents are discussed as tools for extending shelf life while preserving desirable sensory attributes. By integrating omics-based flavor characterization, green extraction, and biorefinery approaches, this Issue encourages interdisciplinary studies that connect food chemistry, biotechnology, and marine resource sustainability to achieve premium-quality seafood with enriched flavor and health-promoting properties.

Myofibrillar protein (MP) aggregation in solutions with NaCl concentrations below 0.3 M results in poor solubility. Ultrasound-assisted glutaminase treatment (UGT) was applied to improve MP solubility in a low-salt solution (containing 0.1 M NaCl). The solubility increased with ultrasonic power and time, peaking at 44.34% (480 W, 15 min) and reaching 61% after UGT. Subsequently, the effect of post-sonication heat treatment (60 °C, 30 min) on the physicochemical and structural characteristics of ultrasound-enzyme treated MP (UEMP), prepared under specific ultrasonic conditions (480 W, 20 min), was systematically investigated. The findings revealed that UEMP exhibited higher hydrophobicity, sulfhydryl content, and turbidity, but reduced particle size, ζ-potential, and fluorescence, suggesting disulfide disruption and exposure of hydrophobic residues. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis revealed weakened high-molecular weight bands and intensified low-molecular weight bands. Fourier-transform infrared spectroscopy confirmed these structural rearrangements, with a blue-shifted amide A band and decreased amide I intensity. Heating further increased the hydrophobicity and fluorescence without altering the size, ζ-potential, or molecular weight. The red shift in the amide A band suggests reinforced local ordering. Rheology analysis showed non-Newtonian shear-thinning behavior, which was unchanged by UGT or heating. Collectively, UGT with moderate heating enhances MP solubility and thermal stability by disrupting stabilizing bonds and modulating the structure. Full article
