PURPOSE: A method for non-destructive analysis of one seed grain by near infrared ray absorption spectrum is provided to precisely analyze the components and characteristics of one seed grain in a short time without using any additional chemical analysis equipments. CONSTITUTION: A method for non-destructive analysis of one seed grain by near infrared ray absorption spectrum includes the steps of measuring near infrared ray absorption spectrums(400-2500mm) of 30-100 seeds of selected grain samples by a horizontal manual module, correcting absorbancy per wavelength measured by 30-100 grains respectively with a single average absorption spectrum per wavelength, randomly distinguishing 150 averaged absorption spectrum into about 100 estimation model developing models and about 50 estimation model testing models, correcting the uniformity of the samples by using a sieve of 60 mesh after preparing powdered samples, testing the moisture content of the powdered samples by drying for 2 hours in a drier of 105C, precisely carrying out chemical analysis of contents of components such as protein and fat contained in the powdered samples twice or more, removing samples of which a difference in the chemical analysis is beyond a range of 0.2-0.4% from the models, inserting real component contents of which moisture contents are corrected into the measured average absorption spectrum, carrying out the statistic analysis for setting optimum estimation models for the respective components, and selecting the optimum estimation models by discriminating the precision of the estimation models.
