NIR-based method for rapidly determining soluble sugar in chestnut kernels

The invention discloses a Chinese chestnut seed kernel soluble sugar rapid determination method based on NIR, and the method comprises the following steps: collecting spectral data of Chinese chestnut seed kernels to obtain the spectral data; the content of soluble sugar in the chestnut kernels is measured, chemical detection data are obtained, and spectral measurement corresponds to the chemical detection data one by one; a partial least squares regression method is combined with interactive verification to construct a calibration model for the obtained spectral data and chemical detection data, the calibration model is added into an application program and then imported into detection equipment, the detection equipment is started, and the program can be used for directly carrying out rapid and nondestructive determination on the soluble sugar content of the chestnut kernels. The method provided by the invention can realize rapid, efficient and nondestructive determination of the soluble sugar content of the
