We used the discriminant analysis of curd cheese during storage by Fourier transform near infrared spectroscopy method (FT-NIRs). Olomouc curd cheese samples were stored at 5 and at 20&deg;C during seven weeks. The spectra of samples were measured at the integration sphere in reflectance mode with the use of a compressive cell in the spectral range of 10&nbsp;000&ndash;4000 cm<sup>&ndash;1</sup> with 100 scans. Ten principal components were used for all the calibration models. Great similarity between the samples stored at 5 and 20&deg;C was found. Twelve samples stored at 20&deg;C for 1 week and 2 samples stored at 20&deg;C for 2 weeks were classified as samples stored at 5&deg;C. Different results were found out by comparing the storage time. 100% variability was described between the spectra scanned in different weeks of storage at 5&deg;C and 99.9% variability was obtained for the samples stored at 20&deg;C. Thus, the discriminant analysis of Olomouc curd cheese by FT-NIRs is a suitable method for the determination of ripening time. &nbsp;
