Determination of the colorants ın a beverage sample by chemometrıc methods using an ultraviolet spectrophotometer

In this study, color materials in powdered beverage samples were determined by chemometric methods using and UV/VIS spectrophotometer. From the chemometric methods, the principal component regression (PCR) and the partial least squares method (PLS) were successfully applied in the determination of the amount of sunset yellow and β-carotene contained in a powdered beverage. The results obtained with the help of applied chemometric methods are extremely fast, simple and reliable results.
