Óleo de resíduos da filetagem de tilápia (Oreochromis Niloticus) para produção de biodiesel

Abstract

The potential of oils extracted from tilapia filleting wastes for the production of biodiesel is analyzed. Crude oils, extracted from heads, carcasses and viscera, were analyzed for physical, chemical and yield factors. DIC with three treatments (heads, carcasses and viscera) and five replications were employed for the statistical analysis of data. There were significant differences in oils (p<0.05). Since viscera oil had the highest yield rate, it was selected for further studies. Later, treatments comprised neutral crude oil and refined oil from viscera, with different volumes of NaOH 16%. DIC, 2x3, with three replications was applied for statistical analysis. Variables comprised acidity index, saponification index, peroxide index and iodine index. Yield of all types of biodiesel obtained were assessed. Oil from viscera was the most adequate oil for the production of biodiesel due to its high yield and compliance to ANP norms.
