TISSUE DENSITY ANALYSIS METHOD OF GINSENG FRESH ROOT BY NEAR INFRARED SPECTROSCOPY

摘要

An analysis method of the density of ginseng tissues through near infrared spectroscopy is provided to improve measuring accuracy and shorten measurement time by measuring density of the ginseng tissues through near infrared ray of 932~974nm range. An analysis method of the density of ginseng tissues through near infrared spectroscopy comprises: a step of calculating experimental value data by measuring tissue hardness to a plurality of ginsengs; a step of collecting spectrum which is reflected by irradiating the near infrared ray on a plurality of ginsengs; a step of calculating the standard measuring formula by analyzing the experimental value data and the collected spectrum with multi-variate regression; and a step of substituting the standard measuring formula for the ginseng reflectance spectrum of the experimental value and verifying the standard measuring formula. The near infrared ray is the range of 932~974nm.
