从烤鳗下脚料中提取测定牛磺酸的研究

Study on extracting and measuring taurine from the eel scraps

建立了用光度法测定烤鳗下脚料中牛磺酸的含量,加标回收试验的结果表明,该法的回收率达93%,相对标准偏差为2.4%,可用于水产品中牛磺酸含量的准确测量。从下脚料中提取牛磺酸的工艺流程设计合理,方法简便。从烤鳗下脚料中提取牛磺酸的方法不仅为烤鳗下脚料的综合利用研究提供了新的途径,而且可作为其它水产原料中牛磺酸提取测定的方法。

The method of extraction and measurement of taurine from eel scraps was established.The concentration of taurine in the eel scraps was measured by spectrophotometry,and the results of the spiked tests—the recovery of 93%and the RSD2.4%,indicated that the method was accurate.The process of extracting taurine from eel scraps was desig ned properly and simply.The method of extraction and measurement of taurine can be used for the full utilization of eel scraps and other aquatic products.
