RESUMO:

Nowadays, coffee is one of the most produced crops and one of the most consumed products in the world background and Brazil is its largest exporter of this grain. However, during its processing, about 20% of its production is converted into solid residues, which presents a large amount of bioactive substances such as phenolic compounds, being produced by the secondary metabolism of plants and of wide interest for the pharmaceutical and food industries. Therefore, finding alternatives in obtaining these substances more economically and in a way that does not affect the environment has been the target of several studies. The adsorption process using macroporous resins has been distinguished in this scenario, since it is an efficient method in the separation and in the application on industrial scale as these materials have high surface area, large diameter, medium pores, high mechanical resistance and easy regeneration. The use of ethanol and water as solvents presents are an alternative to the traditional solvents, whereas the use of the mixture is low cost, presents no risk to health, environment and is not toxic, which allows its use in the food industry. Although the enormous potential of this process, no work using macroporous resins in the separation of phenolic compounds from coffee husks is available in the literature. Thus, the objective of this work is to separate phenolic compounds from the coffee husk using ethanol solution in water and to evaluate the adsorption and desorption of these compounds in different types of macroporous resins.
