摘要：

Several partial Least squares (PLS) calibration models were performed on spectra of standards of restored milk measured with two different types of near infrared spectrophotometers [800-1080 nm]; the most reliable instrument was chosen using a self-made PLS program, ISCAP, the efficiency of which was evaluated with the Quant2 OPUS program. Then ISCAP was applied to develop and test a method of moisture prediction in milk powder based on diffuse reflection spectra received in a NIR spectrometer (1100-1700 nm) equipped with a remote fibre-optic probe The reference moisture was determined by thermo-gravimetric analysis.
