Non-destructive testing method of the ingredients such as vegetables by near-infrared spectroscopy, and the apparatus

摘要

Measurement method of the present invention may be vegetables and lettuce, and spinach, as measured directly leaves these to be non-destructively measured and nitrate concentration in vegetables by near infrared spectroscopy. That is, after irradiating the vegetables to be inspected wavelength light a portion or range of range of wavelengths 400nm~2500nm, to obtain the absorbance spectrum data by detecting the reflected light, the transmitted light reflected or transmitted light, in the This is a method of analyzing qualitatively or quantitatively the component contained in and the vegetables by substituting the measurement model which is created in advance, the absorbance of a specific wavelength or measuring all wavelengths.
