FEASIBILITY STUDY OF OIL MARINE FISH GUTS (Seriola Dumerlii (Arabaiana), Thunnus spp (TUNA), mackerel Scomberomorus (MACKEREL) and Carcharrhinus spp (TION)) SOLD IN ARACAJU UP FOR THE PRODUCTION OF BIODIESEL
Fish and its products are recognized as an important food alternative for human population, they represent sources of high quality protein and good digestibility, lipids, minerals, fatty acids and fat soluble vitamins. Fish industry represents a vast potential for the volume of generated waste, because their discharges can be processed into successfully marketing products, silage as an example, flour, fish oils, biodiesel, and other fermented products. Animal fat oils and those used for cooking food are used as an alternative source of raw materials for the biofuels production, but the oils whose origin comes from organic waste disposed by fish processing industries are being studied as a way of maximizing the reuse of these maximizing raw material usage, avoiding wastage and walking thus for a sustainable development. Due to lack of knowledge about the potential of these wastes and the search for alternative raw materials to improve energy production, the objective of this study was to assess the viability of the extracted oil from the guts of marine fish production of biodiesel. Analyzes were performed to determine the acidity, iodine and moisture levels, kinematic viscosity, saponification number and density of this oil. Analyzed to characterize the guts of marine fish and analyzes to determine the levels of acidity, iodine and moisture, the kinematic viscosity, the saponification number and density of the oil. It was observed that the guts of marine fish showed high fat and protein and oil extracted from the guts of marine fish as an alternative feedstock for biodiesel production.
