Abstract:The origin and season are important basis for judging the quality of abalone. Inductively coupled plasma mass spectrometry(ICP-MS) was used to determine the content of 16 inorganic elements in the samples from different habitats and seasons. The inorganic element database of Haliotis discus hannai was established and combined with cluster analysis for 18 wrinkles. The abalone samples were divided into regions to explore the feasibility of traceability of inorganic elements to traceability of the origin of Haliotis discus hannai. The results showed that the abdomen of the Haliotis discus hannai disk was rich in trace elements required by the human body, and the content and type of inorganic elements were affected by the season and the growth environment. The content of elements in summer and autumn was generally higher than that in winter and spring, and the content of Fe in autumn was ten. Times or even a hundred times higher than the other three seasons. The results of cluster analysis showed that the classification was significantly correlated with the origin and sea area distribution of the Haliotis discus hannai samples, but the effect of identifying the origin was related to the season.
