Encapsulado de probiótico a partir da extração da lignina da casca do arroz

Abstract

Brazil is one of the largest rice producers and consumers in the world, standing in the nineth position, and one of the consequences of this agronomy sector is the generation of residues, mainly from rice husks. Seeking for an alternative in addition to disposal and burning, emphasizing a reduction in environmental impact, other destination paths are possible to enhance value to this residue. The research approaches the use of this residue in order to extract a high quality lignin, through the ethanosolv process. With the use of a extraction system, where there is a solution of rice husk, ethanol, water and hydrochloric acid, on an increasing heat surface purpose of reaching the ideal temperature for the process, the objective can be fulfilled. After obtaining the lignin, the material goes through a performance check that proves its efficiency. Thus, a study on its use in encapsulation can be carried out, taking advantage of its characteristics, such as delaying the release of the encapsulate. With the goals achieved, it was made possible to perform the extraction with satisfactory yield and subsequente success in the encapsulation of the probiotic, as verified by the experiments. Therefore, it can be concluded that the development of a value-added product for use in the industrial sector has been accomplished.
