Brazil has emerged as producer of alternative fuels derived from biomass, such as biodiesel, which can replace fossil diesel and is less polluting. However, there is a concentration of income in the production chain, since most of the biodiesel produced in the world is derived from soy oil from major producers. This scenario also corresponds to Brazil, and Tocantins state could not frame in the National Program for Biodiesel Production. In this study, the biodiesel was produced from beef tallow obtained from slaughterhouses in the city of Gurupi-TO. The beef tallow was characterized in its raw state, processed and then the biodiesel was synthesized. We studied the oxidation stability through spectroscopic analysis in the UV-vis, and we observed their stability to oxidation via spectroscopic analysis in the UV-vis, and observed that the beef tallow biodiesel showed increased absorption in 234 nm and 268 nm after reduction in oxidative stress. We checked an early stage of oxidation after the seventh day with the maximum concentration of primary oxidation compounds. We obtained a satisfactory biodiesel within some of the parameters of the National Agency of Petroleum, Gas Naturale Biofuels (ANP).
