Quality inspections in agricultural product industries is a critical step to ensure high standard of the products. The main purpose of this present study is to apply the near infrared spectroscopy as a rapid and simultaneous method in determining inner quality parameters of intact mango fruits as vitamin C and total acidity. Absorbance spectra data of mango samples were acquired using a portable sensing device NIRS in wavelength region of 1000-2500 nm and resolution windows 0.02 nm. On the other hand, actual vitamin C and total acidity contents of mango fruit were measured by means of standard laboratory procedures. Prediction model were built using raw and enhanced spectra data with partial least square regression approach. The results showed that both quality parameters can be determined simultaneously with maximum correlation of 0.92 for vitamin C and 0.94 for total acidity. It may conclude that near infrared spectroscopy can be employed for a rapid and environmental friendly approach in mango quality inspections.
