Studies have shown that storing pre-rigor frozen fish at subzero temperatures before thawing might suppress pH drop after thawing in some migratory fish. Therefore, the mechanisms involved in pH maintenance and the effects on the quality of fish muscle were investigated here. Frozen spotted mackerel (Scomber australasicus) was stored at -10°C for 1-10 d (hereinafter referred to as “-10°C treatments”). pH, water retention, and the changes in primary metabolite concentrations were investigated in the frozen and thawed muscles. When the -10°C treatment lasted for 5 d or longer, the thawed muscle maintained a min. pH of 6.2, and the water-retention and water-reabsorption capacities of the frozen-thawed spotted mackerel muscle of -10°C treatment samples increased compared with the control sample. In the -10°C treatments, NAD (NAD) was consumed and glycolytic intermediate products accumulated in the frozen muscle. This result suggests anaerobic glycolysis was inhibited. The results of this investigation indicate that -10°C treatments before thawing may increase the meat quality in frozen spotted mackerel. This study involved multiple reactions and reactants, such as ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate (cas: 1094-61-7Related Products of 1094-61-7).
((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate (cas: 1094-61-7) belongs to amides. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. In simple aromatic amides, fragmentation occurs on both sides of the carbonyl group. If a hydrogen is available in N-substituted aromatic amides, it tends to migrate and form an aromatic amine and the loss of a ketene.Related Products of 1094-61-7
