Free amino acids have been shown to function as
osmoregulators in crustaceans,8,24 and they also are
a major contributor to the flavor of seafoods.25–27
Therefore, changes in environmental salinity
might possibly be used to produce freshwater
shrimp with different flavor characteristics. In
addition, the amino acid composition and concentration
in the muscle of shrimp may affect muscle
quality. In this study, the metabolic pools of free
amino acids in low salinity species contributed to
intracellular osmolarity, which resulted in lower
food qualities and poorer flavor.
