RELATO DE ESTÁGIO: CONTROLE DE QUALIDADE DA CADEIA PRODUTIVA DE BIODIESEL DE ÓLEO DE SOJA E SUA CONFORMIDADE COM PARÂMETROS TÉCNICOS

Abstract

This work aimed to report the activities carried out during the supervised internship in an industrial quality control laboratory, focusing on monitoring the biodiesel production process and the physicochemical analyses. The process begins with the receipt of soybeans, followed by the stages of cleaning, drying, oil extraction, refining, and transesterification, until obtaining the final product. Throughout the process, critical control points were identified, at which essential analyses are performed to ensure quality. Among the analyses performed, notable ones include the determination of moisture, acidity index, soap content, phosphorus, chlorophyll, oxidative stability, flash point, kinematic viscosity and water content. The results obtained were compared with the limits established by regulatory agencies, such as ANP and MAPA, highlighting the compliance of the biodiesel produced with current specifications. The experience provided practical application of the knowledge acquired throughout the Food Engineering course, contributing to the development of technical skills and critical thinking in the area of quality control. As a result of the performance during the internship, there was confirmation in the position of laboratory analyst, emphasizing the importance of practical experience for entry into the job market.
