Várias empresas nacionais e internacionais empregam matéria-prima vegetal na elaboração de seus produtos, o que torna indispensável o cultivo comercial e o beneficiamento pós-colheita destas espécies. O objetivo deste trabalho foi avaliar o teor de óleo essencial de carqueja [Baccharis trimera (Less.) DC.], em três embalagens diferentes ao longo de um ano de armazenamento. Observou-se que ao longo do armazenamento, a embalagem de papel Kraft foi a que melhor preservou a integridade de certas características físicas e químicas do produto, assim como, manteve o teor de óleo ao longo de um ano de armazenamento.

The use of medicinal plants as therapeutic source is ancient and has increased in value in recent years for both the population and the science. Several national and international companies use raw plant material in the preparation of their products, making essential the commercial cultivation and the post-harvest processing of these species. The aim of this study was to evaluate the essential oil content of [Baccharis trimera (Less.) DC.] in three different packages over one year of storage. During storage, Kraft-paper package best preserved the integrity of some physical and chemical characteristics of the product and maintained the oil content for one year of storage.

Chemical Variability in the Composition of Zhumeria majdae (Rech. F. & Wendelbo) Essential Oil According to Storage Time and Temperature

“…In this study, the essential oil composition of Z. majdae was assessed at different temperatures and storage times. The harvesting and storage are important factors affecting the essential oil quality and chemical profile [39,40]. It has also been shown that the increase of temperature during storage decreases product quality [41][42][43].…”

Influence of storage time and temperature on the chemical composition of the essential oil of Hyptis pectinata L. Poit

“…The harvesting and post-harvesting are extremely important for obtaining essential oil with higher quality, composition and for the product reaches the end of production chain (Ehlert et al, 2013;Silva et al, 2013). Thus, it is necessary to establish criteria to insure quality during processing and storage (Souza et al, 2015).…”

“…Thus, it is necessary to establish criteria to insure quality during processing and storage (Souza et al, 2015). However, essential oil suffer numerous reactions, making the key storage quality and preservation of the physical and chemical composition (Guimarães et al, 2008;Silva et al, 2013).…”

Influence of Storage Conditions on Quality Attributes of Medicinal Plants

“…During storage, metabolic activity must be reduced, making medicinal plants less susceptible to deterioration. This can be achieved by reducing the water content of the product to safe levels, cooling or use of modified atmosphere in the system in which the medicinal plants are stored [7,11,12].…”
