A method for constructing a sea cucumber origin tracing model based on element content and stable isotope and a method for identifying sea cucumber origin

By measuring the C, N, H, and O elements and stable isotopes of sea cucumbers and combining them with a linear discriminant analysis (LDA) model, the problem of insufficient accuracy in tracing the origin of sea cucumbers in existing technologies has been solved, achieving efficient and accurate origin identification.

Abstract

The application provides a sea cucumber origin tracing model construction method and a sea cucumber origin identification method based on element content and stable isotopes, and relates to the technical field of aquatic product origin tracing. 13 C, δ 15 N, δ 2 H and δ 18 O values of the sea cucumber samples from different origins are determined to obtain determination data of the sea cucumber samples from different origins; linear discriminant analysis is performed with the determination data as independent variables and the origins as observation variables to obtain an LDA model, and the LDA model is a sea cucumber origin tracing model. The technical scheme provided by the application can efficiently and accurately realize sea cucumber origin tracing, and has the advantages of simple operation, low cost, accurate classification results, strong interpretability and the like, and has high application value and popularization prospect.
