Background: In Brazil, over the last few years there has been an increase in the production and consumption of goat cheeses. In addition, there was also a demand to create options to use the whey extracted during the production of cheeses. Whey can be used as an ingredient in the development of many products. Therefore, knowing its composition is a matter of utmost importance, considering that the reference methods of food analysis require time, trained labor and expensive reagents for its execution. Methods: Goat whey samples produced in winter and summer were submitted to proximate composition analysis (moisture, total solids, ashes, proteins, fat and carbohydrates by difference) using reference methods and near infrared spectroscopy (NIRS). The spectral data was preprocessed by baseline correction and the Savitzky?Golay derivative. The models were built using Partial Least Square Regression (PLSR) with raw and preprocessed data for each dependent variable (proximate composition parameter). Results:The average whey composition values obtained using the referencedmethods were in accordance with the consulted literature. The composition did notdiffer significantly (p> 0.05) between the summer and winter whey samples.The PLSR models were made available using the followingfigures of merit:coefficients of determination of the calibration and prediction models (R2cal andR2pred, respectively) and the Root Mean Squared Error Calibration and Prediction(RMSEC and RMSEP, respectively). The best models used raw data for fat andprotein determinations and the values obtained by NIRS for both parameters wereconsistent with their referenced methods. Consequently, NIRS can be used todetermine fat and protein in goat whey.
