Monitoramento da qualidade de óleo essencial de Piper aduncum para a inserção de mercado

Abstract

From an economic point of view, the rich flora of the Amazon is still little exploited. This exploitation is mostly used in the preparation of clothing flavorings, aromatic baths or regional fragrances commonly sold at Ver-o-Peso. The management and domestication of Piper aduncum (Piperaceae), rich in essential oil containing dilapiol, a potent insecticide, fungicide, larvicide, bactericide and molluscicide, was done by the Goeldi Museum in the 1990s. In the present work, an integrated study of the market insertion and chemical quality of Piper aduncum essential oil was carried out, based on management information obtained in previous studies, in an attempt to make the oil available for industrial testing. The collected material was distilled from two different processes (fresh and dried material), differing only in the fact that the second process requires a drying process in an oven, which lasts seven days, after which the material was milled and then distilled. The results obtained between the two processes are significantly different: in the process with fresh material, the percentage of dilapiol oil was 1.3%, with a moisture-free base equal to 70%, while in the process in which dried material was used, the percentage of oil was 1.79%, with a moisture-free base equal to 10%, justifying the difference in yields in the use of processes where the sample is dried. The distillation of the essential oil in a field distiller took place in the Chemical and Food Engineering Department of UFPA, with a yield that ranged from 2 to 2.5% according to the weight of the dry biomass.
