ABSTRACT

Introduction: Matricaria recutita L. (chamomile) is one of the medicinal species used by the pharmaceutical industry. When dry flowers are used in the manufacture of a phytoproduct, the drying process is critical, for it has a direct impact on quality.
Objective: Characterize water outlet dynamics during natural and artificial drying of Matricaria recutita L. (chamomile).
Methods: Postharvest management technology considered harvest stages, weighing, drying, packaging, sealing and storage. In the artificial process, average temperature and relative humidity were 40°C and 50%, respectively. In the natural process, average thermodynamic parameters were 27.1 ± 5.5°C and 77.4 ± 5.0%. Both processes included an evaluation of mass-energy exchange and diffusion mechanisms.
Conclusions: Characterization of the drying kinetics of chamomile describes the behavior of the extraction dynamic of a species with a heterogeneous system consisting of petal, receptacle and flower. It also provides production with technical elements that may be decisive to choose artificial or natural technology.
