Food adulteration which is economically motivated (i.e., food fraud) an incentive for the development and application of new fast detection methods/instruments. An example a method that extremely environmentally friendly near-infrared spectroscopy (NIRS). Therefore, goal this research was to examine potential its in monitoring blended sunflower/olive oils compare two types NIRS instruments, one portable micro-device, could be used assess purity olive oil anywhere would useful inspection services. Both NIR devices (benchtop portable) enable absorbance wavelength range from 900 1700 nm. Extra virgin (EVOOs) “ordinary” (OOs) large small producers were investigated, diluted with sunflower proportions 1–15%. However, appearance different salad have defined share EVOO stated on label (usually 10%), possibilities recognition manipulation these tested; therefore, also added The composition fatty acids, color parameters, total dissolved substances conductivity pure “adulterated” monitored. Standard tools multivariate analysis applied, such as (i) main components qualitative classification (ii) partial regression using least square quantitative prediction proportion impurities acids. Qualitative models proved successful classifying (100%) investigated oils, regardless whether thinner or oil. Developed relating measured parameters scans, resulted values R2 ≥ 0.95 reliable (RPD > 8) acid predicting percentage impurity while attributes less successfully predicted device 2–4.2). Although device, potentials remained at level (e.g., parameters), it important emphasize both tested not only but OO 1–15% same
