Three different types of filter paper with different pore sizes and different filtration rates were used in the middle of the microfluidic platform, as a material for soaking a blended olive oil and high-oleic sunflower oil. The rapid prototyping xurographic technique was used to fabricate the complete microfluidic platform. For testing purposes, oil blends in various proportions were deposited through the inlet on the top of the platform. The variation in electrical resistance at room temperature was measured, using the Chemical Impedance Analyzer and different blended oils were successfully detected. Additionally, a prototype of electronic device was developed for acquisition and displaying measured data, based on the created microfluidic platform | URI: | https://open.uns.ac.rs/handle/123456789/32460 | ISSN: | 09567135 | DOI: | https://doi.org/10.1016/j.foodcont.2021.107888 | Rights: | Attribution-NonCommercial-NoDerivs 3.0 United States |
