Comparative of quality of wild-captured and farmed Sebastes schlegeli

In order to find out the quality differences of Sebastes schlegeli in different living conditions, the primary nutrients, textural and FTIR properties of wild-captured and farmed Sebastes schlegeli were compared and analyzed. The results showed that the moisture content of wild-captured Sebastes schlegeli was significantly higher than farmed ( p < 0.01) , while the contents of crude protein and crude fat of wild-captured Sebastes schlegeli were significantly lower than farmed ( p < 0.05) .The contents of total amino acids and essential amino acids and delicious amino acids of wild-captured Sebastes schlegeli were significantly higher than farmed ( p < 0.05) . The essential amino acids index ( EAAI) of wild-captured Sebastes schlegeli was higher than farmed.The contents of MUFA, ARA and EPA of wild-captured Sebastes schlegeli were significantly higher than farmed ( p < 0.05) , while the contents of DHA were significantly lower than farmed ( p < 0.05) . The adhesiveness of wild-captured Sebastes schlegeli was significantly lower than farmed ( p < 0.05) , while the springiness and chewiness of wild-captured were significantly higher than farmed ( p < 0.05) . There were obvious differences in the characteristic peaks of fatty acids in the FTIR. It was a validation on significant differences of fatty acids composition between wild-captured and farmed Sebastes schlegeli.The results indicated that, there were significant differences on the basic nutrients, amino acids, fatty acids and textural properties of Sebastes schlegeli in different living conditions.These could be used as basic information and reference in order to study on quality evaluation and grading.
