摘要
A method for testing cellular level water content and distribution in fruit and vegetable tissues based on Raman spectroscopy comprises preprocessing of samples, acquisition and preprocessing of imaging spectra, Gaussian peak-separation fitting of imaging spectra, pseudocolor imaging according to the fitting results, and visualization of distribution of water content and water bonding state at the cell level. The distribution of water content and water binding state is visualized at the cellular level in the fruit and vegetable tissues for the first time, and relatively reliable quantitative analysis results of the content of water with different bonding states according to the visualization imaging results is obtained. The new method for testing cellular level water content in fruit and vegetable tissues solves the current problem of not being able to detect cellular level water changes in fruit and vegetable processing, and has a good prospect for the research on fruit and vegetables processing.
