The effects of modified atmosphere packaging (MAP) in combination with superchilling (−1.3 °C) on the physicochemical properties, flavor retention, and organoleptic evaluation of turbot samples were investigated during 27 days storage. Results showed that high-CO2 packaging (70% or 60% CO2) combined with superchilling could reduce the productions of off-flavor compounds, including total volatile basic nitrogen (TVB-N) and ATP-related compounds. Twenty-four volatile organic compounds were determined by gas chromatography–mass spectrometry (GC/MS) during storage, including eight alcohols, 11 aldehydes, and five ketones. The relative content of off-odor volatiles, such as 1-octen-3-ol, 1-penten-3-ol, (E)-2-octenal, octanal, and 2,3-octanedione, was also reduced by high-CO2 packaging during superchilling storage. Further, 60% CO2/10% O2/30% N2 with superchilling (−1.3 °C) could retard the water migration on the basis of the water holding capacity, low field NMR, and MRI results, and maintain the quality of turbot according to organoleptic evaluation results during storage

“…In our previous research [24], the eugenol concentration used in the present research was 1.5% (v/v) and the microencapsulated emulsion was prepared according to Li et al [79]. A total of 150 µL eugenol and 750 mg β-cyclodextrin (β-CD) were stirred mechanically in a beaker and then 5 g Tween-80 was added to make them homogeneously dispersed.…”

The purpose of this research was to explore the fresh keeping effect of modified atmosphere packaging (MAP) with different gas ratios combined with gelatin active coatings containing eugenol on Chinese sea bass stored at −0.9 °C for 36 days. The results showed that MAP3 (60% CO2/10% O2/30% N2), together with gelatin active coatings containing eugenol, could prevent water loss, which maintained high field NMR, MRI, and organoleptic evaluation results. This hurdle technology could also effectively delay the bacterial reproduction, protein degradation, and alkaline accumulation, so it showed the lowest K value, total volatile basic nitrogen, free amino acids, total viable count, Pseudomonas spp., and H2S-producing bacteria, which better maintain the quality of sea bass.

“…Sea bass contains high protein and moisture contents. Therefore, it is highly perishable from endogenous enzymatic activities, protein oxidation, and microbial growth (Li, Peng, Mei, & Xie, 2020). Sea bass should be stored at 4 °C to keep the quality and freshness.…”

This project aimed to evaluate the effects of gallic acid (GA) and protocatechuic acid (PA) grafted onto chitosan (CS) on the improved quality of sea bass (Lateolabrax japonicus) during refrigerated storage. The incorporation of GA and PA onto CS (CS‐g‐GA and CS‐g‐PA) were achieved by the carbodiimide‐mediated grafting procedure. Samples were treated with different solutions (deionized water [CK], 1% CS [m/v], 1% CS‐g‐GA [m/v], and 1% CS‐g‐PA [m/v]) for 10 min, which were then stored at 4 °C. Microbiological quality, including total viable counts (TVC), psychrophilic bacterial counts (PBC), Pseudomonas bacterial counts, and H2S‐producing bacterial counts were measured. Physicochemical parameters, including pH, total volatile basic nitrogen (TVB‐N), thiobarbituric acid (TBA) value, water holding capacity (WHC), and K value, were measured. The changes in protein characteristics, including sulfhydryl groups (SH), Ca2+‐ATPase activity, sodium dodecyl sulfate‐polyacrylamide gel electrophoresis (SDS‐PAGE), and tertiary structure of protein were analyzed periodically, along with texture profile analysis (TPA). The results demonstrated that the CS copolymers treatment exhibited better preservation effects. The CS‐g‐GA and CS‐g‐PA treatments could significantly inhibit the growth of microorganisms and retard the increase of pH, TVB‐N, TBA, WHC, and K‐value during refrigerated storage compared with the CK and CS groups. Additionally, the CS‐g‐GA and CS‐g‐PA treatments could delay the protein oxidation by keeping a higher SH level and Ca2+‐ATPase activity. The CS copolymers treatment could also extend the shelf life for another 6 days compared with that of CK. As a result, CS copolymers can be employed in a promising method for the preservation of sea bass. Practical Application The incorporation of gallic acid and protocatechuic acid onto chitosan (CS‐g‐GA and CS‐g‐PA) showed superior antioxidant and antimicrobial activities when applied on sea bass. The CS‐g‐GA and CS‐g‐PA coatings could maintain the quality and freshness of refrigerated sea bass. Additionally, this research could provide a theoretical basis for the application of graft copolymers on the preservation of aquatic products.
