基于灰色关联度和Vis-NIR的不同贮藏方式下番茄光谱特性分析
Analysis of spectral characteristics of tomatoes in different storage methods with grey relational analysis and visible-near infrared spectroscopy
摘要
Abstract
[Objective]The purpose of the study was to determine the main contribution factors which affected tomato qualities under different storage conditions.[Methods]Spectral characteristics of tomatoes were analyzed using visible and near infrared spectroscopy.Principal component analysis and grey relational analysis were introduced to distinguish tomatoes under different storage conditions and to determine the main contributors of the spectral characteristics.[Re-sults]The results showed the different spectral characteristics of tomatoes under different storage conditions.Three sensitive bands at 1 927,1401,and 1222 nm with accumulated contribution rate of 98.92% were obtained by principal component analysis,and could be used to distinguish tomatoes under different storage conditions.Titratable acid dis-played the maximum correlation with both 1 927 and 1222 nm absorbance value,while soluble solids showed the maxi-mum correlation with 1401 nm absorbance value.[Conclusion]The study results indicated that titratable acid and solu-ble solids were the main indicators that affect tomato qualities under different storage conditions.This study provided a basis for further research on rapid detection of tomato quality using spectral technology.关键词
