Resumo: | Due to the usual biological, antimicrobial and antioxidant activities, the essential oils have a potential interest in several industries as food, pharmaceutical, cosmetics, perfumery, hygiene and cleaning, in the manufacture of paints and in biological control of the agricultural pests. With the market?s growth, alternatives have been sought for economic and social development, while the nature is preserve in to keep natural resources available for the next generations. Aiming at further discussions on the theme environmental preservation, a theoretical and practical research was introduced through the essential oil extraction process of the aromatic plant Pentacalia desiderabilis (Velloso) Cuatrec., by obtaining and characterizing the product allied to proposals for the generated residues destination. In order, the extraction process was done with a pilot steam distillation unit at three different pressure conditions. After the extractive method, are produced: the essential oil and the liquid (aqueous extract and hydrolyzate) and solids (remaining aromatic plant) residues. Three mathematical models were tested to simulate the extraction process. The antioxidant and antimicrobial activity of oil and aqueous extract was evaluated. The essential oil?s chemical composition and aroma was also studied. The solid residue was assess as a possible biosorbent for the adsorption of methylene blue, caffeine and chromium. According to the experimental data, the diffusive one-dimensional model for rectangular geometry proved to be the most adequate. The results also showed that the extracted essential oil, as well as the evaluated solid and liquid residues, have biotechnological potential to be explored. |

Com o crescimento do mercado surgem debates sobre alternativas de desenvolvimento econ?mico, social e que, ao mesmo tempo, preservem a natureza de modo a manter os recursos naturais dispon?veis para as pr?ximas gera??es. Com o objetivo de ampliar estudos que apresentem discuss?es sobre o tema preserva??o ambiental, realizou-se uma pesquisa te?rica e pr?tica em rela??o ao processo de extra??o do ?leo essencial da planta arom?tica Pentacalia desiderabilis (Velloso) Cuatrec., atrav?s da obten??o e caracteriza??o do produto aliado a propostas para a destina??o dos res?duos gerados. Para tanto, a extra??o foi realizada com um equipamento em escala piloto de destila??o por arraste a vapor em tr?s diferentes condi??es de press?es. Ap?s o processo extrativo, s?o produzidos: o ?leo essencial e os res?duos l?quidos (extrato aquoso e hidrolato) e s?lidos (planta arom?tica remanescente). Tr?s modelos matem?ticos foram testados para simula??o do processo de extra??o. Avaliou-se a capacidade de atividade antioxidante e antimicrobiana do extrato aquoso e do ?leo, sendo que este ?ltimo tamb?m foi estudado em rela??o a sua composi??o qu?mica e seu aroma. Analisou-se a utiliza??o dos res?duos s?lidos como poss?veis biossorventes mediante ensaios de adsor??o com azul de metileno, cafe?na e cromo. De acordo com os dados experimentais, o modelo difusivo unidimensional para geometria retangular mostrou-se o mais adequado. Os resultados tamb?m apresentaram que o ?leo essencial, assim como os res?duos s?lidos e l?quidos avaliados, possuem potenciais biotecnol?gicos a serem explorados.Submitted by PPG Engenharia e Tecnologia de Materiais (engenharia.pg.materiais@pucrs.br) on 2018-10-24T19:04:42Z No. of bitstreams: 1 dissertacao.loris.pdf: 3349640 bytes, checksum: 322a19b58e9bb00ff35471c3d49f70e1 (MD5)Approved for entry into archive by Sheila Dias (sheila.dias@pucrs.br) on 2018-10-26T12:32:00Z (GMT) No. of bitstreams: 1 dissertacao.loris.pdf: 3349640 bytes, checksum: 322a19b58e9bb00ff35471c3d49f70e1 (MD5)Made available in DSpace on 2018-10-26T12:38:44Z (GMT).
