Abstract: The near infrared spectroscopy was used in qualitative discrimination of fruit quality of cherry during storage period. The experiment was carried out under different pretreatments and different spectral band conditions, the model of qualitative discrimination was constructed in the spectral range between 4088 nm to 2 4928 nm(near infrared wavelength range 780-2 526 nm), using the first order differential method combined with SNV & D spectral pretreatment method. The identification rate of the model was 997%, and predict accuracy was 889% to 990%, which indicated that near infrared spectroscopy could make good qualitative discrimination on fruit quality of cherry, thereby realizing the rapid evaluation for the fruit internal quality.

Key words: near infrared spectroscopy, cherry, storage period, forecast
