This study evaluated the effect of different concentrations (20, 40 and 60 mg/L) of 3-aminobenzoic acid ethyl ester methanesulfonate (MS-222) on the quality changes in turbot during simulated transport in water. The results showed that the ammonia nitrogen content in the transportation water of each sample increased significantly, and the dissolved oxygen level decreased. The dissolved oxygen content in MS-222-treated samples was higher than that of control group (CK) samples. For turbot flesh quality, simulated transport in water led to a decrease in moisture, fat and protein contents in all samples. The MS-222-treated turbot samples showed higher pH values, glycogen contents, springiness and chewiness values and lower lactic acid contents comparing with the CK samples during simulated transport in water. In addition, the fresh and bitter amino acids in the muscle of turbot increased in each treatment group compared to the non-transported fish at the end of the simulated transport. The results showed that MS-222 treatment could retard the turbot transport stress and improve the quality of turbot during simulated transport in water.

Hydrazine Solution

O-Glycans from pig gastric mucin were released by beta-elimination in 0.2 M triethylamine and 50% aqueous hydrazine solution. The released glycan hydrazides were isolated using Centricon 10 separators, brought to their reducing form and reductive by labelled with p-aminobenzoic acid ethyl ester (ABEE). Labelled products were fractionated into neutral and acid fractions on a Bio-Gel P4 column, calibrated with a mixture of dextran oligosaccharides, labelled according to the same procedure.
