The reuse of Waste Frying Oil (WFO) from food frying processes has been used as a good alternative for the production of biofuel, since it uses vegetable oil as a raw material for this production, after its use in food chain, adding value to this waste and reducing the impact on the environment. This project aims to develop a methodology to evaluate the quality of biodiesel produced from WFO from food frying, as well as to determine its stability during storage. The main conditioning variables that affect the production and storage of this biofuel will be studied, such as: raw material, technological routes, purification processes and oxidative stability, which will be correlated with the quality of the final product through the olfactory profile and according to the standards of the Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP). The electronic nose will be used as an alternative measurement instrument for the determination of important characteristics in the process, besides the techniques of multivariate analysis for the interpretation of the results to be obtained. This research will allow the development of a new analysis methodology for the early identification of raw materials, which will guarantee the final quality and storage of a biofuel of great importance for the country, with considerable reduction of the time and without the need to use sophisticated and costly analyses.
