The attenuated total reflection (ATR) mode in Fourier transform infrared (FT-IR) spectroscopy has been used to detect the sugar transformations of carrots under various storage conditions. The composition of the sugars was assessed by principal component analysis (PCA) and principal component regression (PCR). The changes in the sucrose concentration of the trachea and phloem of the carrot after storage are evident.
