Method for fast detecting indexes of white granulated sugar through near infrared spectrum

Abstract

The invention belongs to the technologies in the technical field of saccharose detection, and particularly relates to a method for fast detecting indexes of white granulated sugar through a near infrared spectrum. A near-infrared spectrograph is utilized for measuring the near infrared spectrum of a sample, measured spectroscopic data is processed through the chemometric technology, a white granulated sugar index calibration model is set up according to the processed spectroscopic data of the calibration set sample and the chemometric technology for white granulated sugar index reference values of the spectroscopic data, the performance of the white granulated sugar index calibration model is evaluated through a verification set sample, and the set-up calibration model is used for predicting the unknown indexes of the white granulated sugar. When the method is used for detecting the indexes of the white granulated sugar, no chemical reagent is needed, manual intervention is not needed, the advantages of being fast and accurate are achieved, high stability is achieved, and the important parameters such as the color value, turbidity, sugar and moisture of the white granulated sugar can be obtained within 5 min.

Description

technical field [0001] The invention belongs to the technical field of sucrose detection, and in particular relates to a method for rapidly detecting white granulated sugar indicators by near-infrared spectroscopy. Background technique [0002] Guangxi is the largest white sugar production province in China. How to produce high-quality white sugar and improve the production technology level in the new era needs to provide a fast and accurate method for testing the quality of white sugar. The existing sugar detection technology methods in sugar factories include instrumental analysis detection method and conventional chemical detection method. Although the instrumental analysis detection method is simple to operate, it has the defect of low detection accuracy, while the traditional national standard chemical analysis method has complex operations, time-consuming and laborious. Shortcomings, poor repeatability, lagging test results, far from reaching the purpose of timely guid...
