Evaluación de insumo homólogo en la etapa de refinación química del aceite de soya

Soybeans are widely used in the food industry due to their ability to produce various by-products, such as soy lecithin, soy milk, soy sauce, and crude soy oil. The latter is the raw material of interest in this work, which must be refined using physicochemical methods to meet certain quality standards and can subsequently be marketed. The chemical refining process is conventionally carried out using caustic soda, phosphoric acid, silica and adsorbent clays. Which eliminate impurities (e.g., metals, phospholipids, carotenoids, etc.) that affect the organoleptic characteristics of the oil. However, this process is expensive due to the high prices of the inputs required (they are generally imported). For this reason, the objective of this degree project was to carry out a techno-economic analysis of a new soybean oil refining process. By replacing the silica currently used in this stage with a lower priced “homologous” agent. Taking this into account, experimental tests were carried out at the facilities of the company financing the project (Duquesa S. A. BIC) and the efficiency of this agent was evaluated by determining the physicochemical properties of the refined oil, such as: acidity, humidity, index refraction and color. Subsequently, a qualitative and quantitative comparison of both processes (the conventional one and using the homologous one) was carried out.
