鱼露是潮汕地区独具特色的调味品,又叫鱼酱油及水产酱油,是潮汕地区常用的调味佳品。鱼露主要以近海海捕鲜负为原料,经发酵精制而成。随着广东沿海地区的工业发展,海洋重金属污染问题较普遍,建立一种能高效、快速、准确测量水产品中多种微量元素含量的方法显得尤为重要。目前对于元素的测定有采用分光光度法、原子吸收法、阳极溶出伏安法、示波极谱法等。这些方法大都具有操作复杂、灵敏度低、检测速度慢、结果偏差大等缺点。
Fish sauce is a unique flavor of Chaoshan region condiments, also known as fish sauce soy sauce and soy sauce, Chaoshan region is commonly used condiment. Fish sauce is mainly fresh seafood as raw material, the refined by fermentation. With the industrial development in the coastal areas of Guangdong and the heavy metal pollution problems in the sea are more common, it is particularly important to establish a method that can efficiently, rapidly and accurately measure the content of trace elements in aquatic products. At present there are spectrophotometric determination of the elements, atomic absorption spectrometry, anodic stripping voltammetry, oscillopolarography and so on. Most of these methods have the disadvantages of complex operation, low sensitivity, slow detection speed and large deviation of results.
