生姜提取液处理过的草鱼在储藏过程中 POV值、TBARS值、LOX酶活的变化规律以及处理前后草鱼挥发性成分的变化情况。实验结果显示,生姜提取液能有效抑制草鱼脂肪 POV值、TBARS值、LOX酶活性的增加,并且经生姜提取液处理后草鱼中由脂肪氧化裂解产生的葵醛、1-辛烯-3-醇等腥味物质均检测不到。综上所述,生姜提取液能够通过抑制草鱼脂肪氧化来脱除草鱼的腥味物质。
In this study,the peroxide value,thiobarbituric reactive substances value,the lipoxygenase activi-ty and the volatile components of grass carp before and after pretreatment by ginger extract were deter-mined.The results showed that ginger extract could inhibit the increase of peroxide value,thiobarbituric re-active substances value,the activity of lipoxygenase of grass carp in the process of storage.The fishy smell components(decanal,1-octen-3-ol)that were produced by fat decomposition were undetected.Therefore, the inhibiting effects of lipid oxidation might play an important role for fishy smell elimination.
