Geographical origin tracing identification method for geographical indication mandarin fishes

Abstract

The invention discloses a geographical origin tracing identification method for geographical indication mandarin fishes. The method comprises the following steps: firstly preparing to-be-detected mandarin fish muscle solution, determining contents of seven mineral elements, namely Ca, Mg, Ti, V, Fe, Se and Rb, in the to-be-detected mandarin fish solution by utilizing an inductively coupled plasmaemission spectrometer and an inductively coupled plasma source mass spectrometer, substituting a determination result into a mandarin fish Fisher function discrimination model, and determining a geographical origin of to-be-detected mandarin fishes by comparing the size of the mandarin fish Fisher function discrimination model. The method disclosed by the invention firstly builds the mandarin fishFisher function discrimination model for three geographical origins, namely Lianhuanhu in Heilongjiang, Qiupu in Anhui and Echeng in Hubei, accuracy is 100% when the discrimintation model is utilizedfor identifying the geographical origin of the mandarin fishes, discrimination accuracy is high, stability is good, repeatability is high, system error is small, and rapid geographical origin tracingidentification on the geographical indication mandarin fishes from different geographical origins is realized, so that the method disclosed by the invention has better practical guiding significanceand extensive popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of authentic attribute discrimination of geographical indication aquatic products. More specifically, it relates to a method for identifying origin traceability of geographical indication mandarin fish. Background technique [0002] Geographical indication agricultural products, as the quality and quality proof of specific products, have unique advantages that other similar products do not have. With a new round of consumption upgrades, landmark products prefixed with place names have established a high reputation and reputation, and at the same time brought very considerable benefits, promoting the development of the regional economy. However, in recent years, with the increase in the value of landmark products, landmark products have been repeatedly violated, and many behaviors such as wrong goods and fake products have not only directly violated the rights and interests of consumers, but also affected th...

AI Technical Summary

Problems solved by technology

Although these types of mandarin fish have been certified as geographical indications, the protection and traceability of their origin is still in the blank stage of technology, and no research on the origin traceability and identification of freshwater fish such as mandarin fish with geographical indications has been reported. As a result, the market and Consumers are also unable to form an effective judgment on these geographical indication mandarin fish products
