This research was to evaluate the effects of gelatin (G) active coating containing eugenol/beta-cyclodextrin (beta CD) emulsions combined with superchilling (-0.9 degrees C) on physicochemical, microbiological, and organoleptic properties of Chinese seabass samples during 30 days of storage. Results showed that seabass samples dipped in G-beta CD coatings containing 0.15% or 0.3% eugenol combined with superchilling could significantly lower the total volatile basic nitrogen, K value, total viable count, H2S-producing bacteria, Pseudomonas spp. and Psychrophilic counts, and free fatty acids. Further, G-beta CD coatings containing eugenol with superchilling (-0.9 degrees C) were more effective in retarding the water migration by low field NMR and MRI results, maintaining quality of seabass during storage according to organoleptic evaluation results.
