Gannan navel orange identification method and system and storage medium

Abstract

The invention discloses a Gannan navel orange identification method and system and a storage medium. The Gannan navel orange identification method comprises the following steps: acquiring navel orange sample sets of multiple producing areas, and dividing the multiple producing areas into Gannan navel orange producing areas and non-Gannan navel orange producing areas; obtaining a navel orange near infrared spectrum set corresponding to each navel orange sample set; establishing a true and false navel orange discrimination model by adopting a partial least square discrimination method; constructing a navel orange producing area classification model for each producing area by adopting a principal component analysis method; and acquiring near infrared spectrum data of the navel oranges to be detected, and inputting the near infrared spectrum data into the true and false navel orange discrimination model and the navel orange origin classification models for identification. According to the invention, identification is carried out based on near infrared spectrum modeling, and compared with a traditional identification mode, the method has the advantages of rapidness, no damage, no pollution, stability, reliability and the like. After the portable near-infrared spectrometer is combined, any navel orange sample in the market can be analyzed, and the purposes of producing area attribution and authenticity identification are achieved.

Description

technical field [0001] The invention belongs to the field of fruit detection, and in particular relates to a Gannan navel orange identification method, system and storage medium. Background technique [0002] Gannan navel orange has been listed as one of the eleven major agricultural products in the country, and has won the title of "Chinese Famous Fruit". Gannan navel orange, as the only product in Jiangxi Province, was shortlisted for the list of geographical indication products negotiated by the Ministry of Commerce and the General Administration of Quality Supervision, Inspection and Quarantine between the China-EU Geographical Indication Agreement. The Gannan navel orange is large in shape, bright orange red, clean and beautiful, with an edible rate of 85%. [0003] However, precisely because of the advantages of Gannan navel oranges, the phenomenon of confusing Gannan navel oranges with navel oranges from other regions has begun to appear on the market. After obtainin...
