Abstract

The invention discloses a rapid modeling method for navel orange sugar content detection based on the spectral peak area of ​​hyperspectral transmission technology, and relates to the technical field of non-destructive detection of internal quality of fruits. This method is: ① Obtain the semi-transmission hyperspectral spectrum of the navel orange sample; ② determine the sugar content of the navel orange sample by chemical method; ③ select the average hyperspectral spectrum of the navel orange sample; ④ calculate the peak area of ​​the hyperspectral spectrum; , for quality testing. The present invention is based on hyperspectral technology and collects hyperspectral spectra of navel orange samples in a semi-transmission manner, which can effectively obtain internal quality information of navel oranges and improve the detection level and efficiency of fruit internal quality; the modeling method has high modeling efficiency and high accuracy, and the model operation The speed is fast, and the internal quality index of the sugar content of the fruit can be quickly detected, and the internal quality of the fruit can be evaluated.

Description

technical field [0001] The invention relates to the technical field of non-destructive detection of fruit quality, in particular to a rapid modeling method for navel orange sugar detection based on the spectral peak area of ​​hyperspectral transmission technology. Background technique [0002] my country is a big fruit producing country, and its output ranks first in the world all the year round, accounting for about 19% of the world's total fruit output. The fruit industry is developing rapidly, showing an upward trend every year. The fruit industry has developed into a pillar industry for farmers in many parts of our country to generate income, and it has greatly promoted and developed agriculture and the economy. Although my country is a large fruit producing country, the overall export volume is still very small, and it is not a strong country in fruit trade. Citrus fruit is the largest fruit in the world. my country's citrus production ranks third among countries in th...
