dc.descriptionThe aim of this manuscript was to show the concepts involving data treatment of RGB based image analysis by univariate and multivariate approaches - the latter using Partial Least Squares (PLS) - using as a practical example application the determination of extravirgin olive oil adulteration. Digital images were collected using a device made of LEDs, batteries and a smartphone and results are shown in a tutorial format using Matlab computing environment. The experiment can serve as an example for teaching the subject for undergraduate and graduate students. A proposta deste tutorial é revisitar o conceito de imagens digitais para explorar o seu uso como metodologia analítica para estimar o percentual de adulterantes em amostras de alimentos de uma maneira didática.
