Extração dos óleos extraídos de resíduos de macroalgas marinhas do litoral Sul de Alagoas para aplicações biotecnológicas

Abstract

The marine macroalgae is already used in various products and for different purposes, ranging from food to medicine. They represent a natural resource that can provide a variety of compounds with beneficial bioactive properties, such as antioxidant, anti-inflammatory, anti-aging actions, among others. Although research is focused on exploring its properties and commodities already sold, they could certainly be further investigated and explored in a sustainable way. On some beaches on the south coast of Alagoas, macroalgae residues can be found in the sand brought by wave action, resulting in problems for public health and resulting in a loss of potential for valuing this resource. Therefore, this work aimed to study the methods of extracting oil from marine macroalgae residues found on the beaches of the southern coast of Alagoas, as well as analyzing the viability of this oil, as a source of fatty acids, for biotechnological applications. The extraction methods to be evaluated were: the ultrasound extraction method and the soxhlet extraction method. After each extraction process mentioned here, the amount of oil obtained was determined. The results of the work showed that the most viable oil extraction process was the hot solvent extraction method and that brown and red marine macroalgae were the ones that presented the greatest amount of extracted oil.
