Preliminary Research of Geographical Origin Traceability of Crassostrea hongkongensisbased on Inorganic Elements Analysis
摘要
Abstract
Abstrct:This work aims at assessing the feasibilityof geographical origin traceability ofCrassostrea hongkongensis through inorganic element traceability technology. Total 20 kinds of inorganic elements inCrassostrea hongkongensis from 7 different place ( Shantou, Huidong, Zhuhai, Taishan, Yangjiang, Zhanjiang and Qinzhou ) was analysed by ICP-MS. Principal component analysis ( PCA ) and cluster analysia ( CA ) were used to analyse the results of inorganic elements inCrassostrea hongkongensis, which can further distinguish the origins ofCrassostrea hongkongensis. Four principal components were extracted from the standardized data, the results of cluster analysis showed that theCrassostrea hongkongensis from 7 different origins were classified into 5 groups. TheCrassostrea hongkongensis from Shantou and Huidong were identified into one cluster, whereas that from Qinzhou and Zhanjiang were identified as another, and Yangjiang, Zhuhai, Taishan were successfully distinguished. The contents of inorganic elements inCrassostrea hongkongensisfrom different origins could be used for geographical origin traceability.关键词
