Métodos alternativos utilizados para extração e refino de óleos vegetais

Abstract

It is visible how the demand for new technologies has increased rapidly in all areas of the industry over the years. In the vegetable oil industry, it would not be different, since in the processing of these, there is a high generation of residues, which can lead to the presence of food contaminants, which is a concern. In this context, there is a demand by the population for products aimed at sustainability and clean processes. In addition, it is expected that the cost of these foods is accessible, requiring a more efficient and economical production. On the other hand, some production alternatives could add value to the product, for example, an oil with a higher concentration of antioxidants. Another factor that could be a differential would be to use appropriate methods in the production stages, to reduce the expenditure of energy, and time and improve the final yield. For this reason, and many other reasons, the search for alternative methods of extracting and refining vegetable oils is increasing. Given this scenario, the objective of this work is to review the alternative methods applied to the process of extracting and refining vegetable oils, aiming to present those that optimize the process or add nutritional value to the product, to show their advantages and disadvantages.
