“…As shown in Table 3, the Deff value ranged from 7.64089 × 10 −11 m 2 /s to 1.47784 × 10 −10 m 2 /s. This result is within the normal value range of Deff in typical food drying processes, which is from 10 −12 to 10 -6 m 2 /s [14]. At temperatures of 50 °C, 55 °C, 60 °C, and 65 °C, the Deff values were 7.64089 × 10 −11 , 1.02741 × 10 −10 , 1.16917 × 10 −10 , and 1.47784 × 10 −10 m 2 /s respectively.…”

Lemongrass is a plant that contains aromatic compounds (myrcene and limonene), powerful deodorants, and antimicrobial compounds (citral and geraniol). Identifying a suitable drying model for the material is crucial for establishing an initial step for the development of dried products. Convection drying is a commonly used drying method that could extend the shelf life of the product. In this study, a suitable kinetic model for the drying process was determined by fitting moisture data corresponding to four different temperature levels: 50, 55, 60 and 65 °C. In addition, the effect of drying temperature on the moisture removal rate, the effective diffusion coefficient and activation energy were also estimated. The results showed that time for moisture removal increases proportionally with the air-drying temperature, and that the Weibull model is the most suitable model for describing the drying process. The effective diffusion coefficient ranges from 7.64 × 10−11 m2/s to 1.48 × 10−10 m2/s and the activation energy was 38.34 kJ/mol. The activation energy for lemongrass evaporation is relatively high, suggesting that more energy is needed to separate moisture from the material by drying.

“…A drying temperature range of 50-65 • C is generally feasible for a wide number of medicinal plants [14] and was selected in this study for a number of reasons. First, it is suggested that, to obtain the highest essential oil content, drying of lemongrass should be conducted in an oven at 45 • C for 7 h [15].…”

“…Medicinal plants have found many industrial uses, especially in the pharmaceutical and food industry, as well as in cosmetics. In pharmaceuticals, plant extracts are especially relevant due to the use of their active substances for medicine development (Rocha et al, 2011). Compounds studied in herbs are essential oil components, as well as the natural pigments such as flavonoids, chlorophylls, and carotenoids.…”

“…Numerous studies deal with the influence of the drying procedure on the amount of pigments as well as other active ingredients. (Rocha et al, 2011). Much research has been done with microwave drying procedure which reduces drying time.…”

“…This drying process is applicable for small quantities of herbs but mass production indispensably requires the use of technical devices. The drying process is basically defined as the decreasing of plant moisture content aimed at preventing enzymatic and microbial activity, and consequently preserving the product for prolonged expiration time (Rocha et al, 2011). From another point of view the drying process may contribute to a regular supply and facilitate the marketing of plants, because the drying results in reduction of the weight and volume of the plant with positive consequences for transport and storage.…”
