Embodiment Construction

[0031] The technology of the present invention will be described in detail below through specific examples, but not limited thereto.

[0032] Embodiments of the present invention are as follows:

[0033] The present invention selects the stable isotope ratio and element and multi-element content as the characteristic fingerprint information of bayberry origin traceability, is mainly based on different isotope compositions mainly affected by environment, topography, climate, soil, biological metabolism type etc. and different fractionation occurs, reflecting Different regions and dietary information, the content of mineral elements is mainly related to the composition and content of mineral elements in the soil environment, water, waste and air, and there are differences in the environment between different regions. Using PCA-LDA joint analysis, the origin traceability database of bayberry was established to identify the origin of bayberry. All data analysis in this embodiment...

Abstract

The invention discloses a Myrica rubra original place tracing method based on stable isotope ratio and multi-element. The method comprises: collecting and pre-processing Myrica rubra samples from different places; subjecting the samples to analysis of the stable carbon, the nitrogen isotope ratio, the stable oxygen, the hydrogen isotope ratio and the multi-element; for the data of the Myrica rubra samples from known areas, using the mode featuring the combination of the PCA method and the LDA method to analyze the data obtained from the Myrica rubra samples from known areas; establishing an original place tracing model to judge the original place of the samples; and using the data obtained from the Myrica rubra samples from unknown areas to be inputted into the original place tracing model to make the analysis and judgment so as to obtain the original place tracing for the Myrica rubra samples from unknown areas. For the first time, the invention adopts the technology featuring the combination of the principal component analysis with the linear judgment to establish a Myrica rubra original place tracing method.

Description

technical field [0001] The invention belongs to the technical field of bayberry origin traceability, and in particular relates to a method for traceability of bayberry origin based on stable isotope ratios and multi-elements. Background technique [0002] Red bayberry is a characteristic fruit in southern my country. Its fruit is bright in color, sweet and sour, and has high nutritional value. Zhejiang, Jiangsu, Fujian and other provinces are the main production areas in China. Among them, bayberry in Zhejiang Province is rich in varieties, high in quality, widely cultivated and large in area. It has become a very competitive fruit for forest farmers in mountainous areas to get rid of poverty and become rich. [0003] Stable isotopes, as the characteristic fingerprint information of the origin traceability of agricultural products, are mainly based on the natural fractionation effect of isotopes. Different isotope compositions are mainly affected by environment, terrain, cli...
