IDENTIFICATION OF VEGETABLE OIL MIXTURES USING COLORIMETRIC PARAMETERS

Abstract

For mixtures of sunflower oil and cottonseed or rapeseed oil, mathematical discriminant analysis was applied and differences in color parameters and content of pigments such as chlorophyll and beta-carotene were demonstrated. The proposed method aims to provide quality control and easy detection of adulteration of sunflower oil by vegetable oils. The significance of individual indicators for modeling was assessed. The models were tested with the results of other independent samples.
