The near-infrared spectroscopy was used in qualitative determination of sweet persimmon shelf-life. The calibration results for shelf-life of sweet persimmon were compared by different spectra pretreatment and different spectral ranges. The second derivative with standard normal variation and detrend spectral pretreatment method were proved to be the best within the range between 1 100 nm to 2 500 nm. The correct identification rate of discriminate model is 97. 8% to 100%,predict accuracy is 88. 9% to 100%. Therefore,the qualitative identification of sweet persimmon shelf-life by near infrared spectroscopy is applicable.
