“…In previous studies, nucleotides catabolism monitoring has been mainly used in fish storage to reflect the freshness (Hong et al ., 2017), and barely applied to freshwater shrimp. There might be three pathways for nucleotide degradation in aquatic products: (i) adenosine triphosphate (ATP) → adenosine diphosphate (ADP) → adenosine monophosphate (AMP) → adenosine (AdR) → inosine (HxR) → hypoxanthine (Hx), (ii) ATP → ADP → AMP → AdR → adenine (Ad), (iii) ATP → ADP → AMP → inosine monophosphate (IMP) → HxR → Hx (Wang et al ., 2007). During fish storage, the IMP pathway is predominant.…”

Effects of refrigerated (3.5 AE 0.5 °C), iced (0 AE 0.5 °C) and superchilled (−3.0 AE 1.0 °C) storage on quality of crayfish (Procambarus clarkii) were evaluated by monitoring the water migration, microbial contamination, biogenic amines accumulation, and nucleotides catabolism during 21 days. The results indicated that superchilling was effective in accelerating the rate of water migration and reducing total volatile basic nitrogen, trimethylamine, total viable bacteria, Enterobacteriaceae and psychrotrophic bacteria of crayfish. Meanwhile, significant (P < 0.05) lower putrescine, cadaverine and tyramine contents were observed in superchilled sample (SS), whereas histamine concentrations were at lower levels (0.76-2.31 μmol g −1 ) in all treatments. In addition, the predominant nucleotides degradation pathway in crayfish was the conversion of inosine monophosphate, which was accumulated massively (3.74 µmol g −1 ) in SS at the end of storage. According to the dynamic changes of inosine and hypoxanthine contents, the shelf life of SS was prolonged to 15 days.

“…These problems are magnified by the way this species is still predominantly stored, that is whole, under ice [ 13 ]. The ice storage is considered to be a useful way of prolonging the shelf life, preserving the original quality of seafood but, at the same time, may lead to the development of unacceptable features [ 14 ]. This method of storage makes the product very sensitive to its initial metabolic state which may compromise not only quality attributes for fresh consumption, but also the technological properties of fish during further industrial processing [ 15 ].…”

Metabolomics as a Powerful Tool for Molecular Quality Assessment of the Fish Sparus aurata

The molecular profiles of perchloric acid solutions extracted from the flesh of Sparus aurata fish specimens, produced according to different aquaculture systems, have been investigated. The 1H-NMR spectra of aqueous extracts are indicative of differences in the metabolite content of fish reared under different conditions that are already distinguishable at their capture, and substantially maintain the same differences in their molecular profiles after sixteen days of storage under ice. The fish metabolic profiles are studied by top-down chemometric analysis. The results of this exploratory investigation show that the fish metabolome accurately reflects the rearing conditions. The level of many metabolites co-vary with the rearing conditions and a few metabolites are quantified including glycogen (stress indicator), histidine, alanine and glycine which all display significant changes dependent on the aquaculture system and on the storage times.

BACKGROUND Depuration is an important process performed to ensure the safety of oyster consumption, and the effect of salinity stress on physiological and ecological characteristics of oyster remains unknow. In this study, the simulated depuration of Crassostrea gigas was performed with the salinities varying from ±10% to ±20% away from that of production area (26, 28, 32, 35, and 38 g L–1), as well as respiratory metabolism, glycolysis, lipolysis, and apoptosis were analyzed. RESULTS (i) The oxygen consumption rate, ammonia discharge rate and enzyme activities related to respiratory metabolism were decreased significantly at salinities of 38 g L–1, indicating that salinity stress triggered the abnormal respiratory metabolism of C. gigas, further, glycolysis was enhanced. (ii) Glycogen decomposition, lactic acid increase, and fatty acid composition modifications were caused by adenosine monophosphate (AMP)‐activated protein kinase (AMPK) ‐mediated during salinity stress. (iii) There was a clear decrease of the condition index and meat yield of C. gigas after 72 h of depuration, especially in salinity 38 g L–1. (iv) Salinity stress would lead to the increase of cytochrome c levels, then cause apoptosis of C. gigas, while heat shock protein 70 (HSP70) would interfere with this process. CONCLUSION Salinity stress had a significant effect on the physiological and ecological response of C. gigas during the depuration process, including respiratory metabolism, glycolysis, lipolysis, and apoptosis. In general, the low depuration salinity fluctuation (±10%) is helpful to maintain quality of C. gigas, as well as the optimal depuration time was 48 h. © 2021 Society of Chemical Industry.
