Abstract: A method is proposed for predicting how the incorporation of unknown raw materials will affect the predictable and realizable properties of end products.

Abstract: A method is proposed to assess the stability and quality of dairy products, primary and main milk-based products including cheeses and plant-based milk alternatives over the storage period by aging dairy products, primary and main milk-based products including cheeses or plant-based milk alternatives under defined conditions, taking regular samples and analyzing them using different parameters. The data sets are analyzed using Principal Component Analysis (PCA) and the Partial Least Square (PLS) calibration method. The calculated ages are compared with the actual sample age and provide a calibration line that can be used to determine the age of unknown samples.
