“…17 Nevertheless, essential oil composition and quality are greatly influenced by oven drying temperature and about 75.7% of essential oils are lost during oven drying at 60°C than at 30°C. 18 This agrees with the principals of Marcotte. 11 Located at the end of the processing line, heating is essential to accelerate evaporation of essential oil.…”

The experiment was conducted in Processing Department, Food Industries Institute, Industrial Research and Consultancy Centre, Khartoum, Sudan to modify Evaporation Test Method of Essential Oil time from 24hours as in British Pharmacopeia to 5-50minutes. Oils extracted from five chosen Sudanese essential oils bearing plants namely Boswellia sp. (Olibanium), Cympobogon citraus (Lemon grass), Mentha spicata (Spearmint), Eucalyptus camaldulensis (Camphorl), Cympobogon proximis (Camel's hay) and one imported Clove buds (Syzygium aromaticum) by hydro distillation according to British Pharmacopeia. The 6 oils were spotted (2mg from each) in filtered papers to form greasy spot and enforced to evaporate under airforced oven at temperatures of 60°C, 70°C, 80°C, 90°C and 100°C consequently. The results obtained showed that the volatilization time was decreased with an increase in temperature from 60°C to 100°C. Evaporation time at 60°C was ranging between 30-50 minutes according to the nature of the essential oil. The minimum evaporation time of essential oil was recorded at 100°C range in a period of just 5-15minutes depending on the oil obtained from different plants. In conclusion under all temperature levels of evaporation the greasy spots of essential oil were disappeared by evaporation and the greasy spot of fixed oil remained.

“…The ratios of percent recovery between fresh sample and ones subjected to drying are presented in Figure 2 . Baydar and Erbaş [ 42 ], Figiel et al [ 19 ], Ghasemi et al [ 43 ] found as well that due to the applied drying method or its parameters the decrease in essential oil yield of green plant parts may range as high as three to five times. Furthermore, Politowicz et al [ 24 ] and Nöfer et al [ 27 ], in the case of mushroom drying, observed similar effects to the ones found in this study.…”

HS-SPME Analysis of True Lavender (Lavandula angustifolia Mill.) Leaves Treated by Various Drying Methods

et al. 2019

True lavender (Lavandula angustifolia Mill.) is a widely used flavoring and medicinal plant, which strong aroma is mainly composed of linalool and linalyl acetate. The most valuable parts of the plant are the flowers, however leaves are also abundant in volatile constituents. One of the main factors responsible for its quality is the preservation procedure, which usually comes down to a drying process. For this reason an attempt to verify the influence of various drying methods (convective drying, vacuum-microwave drying and combined convection pre-drying with vacuum-microwave finishing drying) on the quality of true lavender leaves was carried out by determination of the volatile constituents profile by solid-phase microextraction (SPME) coupled with GC-MS technique. Total essential oil (EO) content was also verified. The study has revealed that the optimal drying method is strongly dependent on the purpose of the product. For flavoring properties convective drying at 60 °C is the most optimal method, while the best for preserving the highest amount of EO is vacuum-microwave drying at 480 W. Furthermore, SPME analysis had shown that drying may increase the value of true lavender leaves by significantly affecting the linalool to linalyl acetate to camphor ratio in the volatile profile.

“…These results have confirmed that carvone is biogenetically related to and formed by limonene, 33 and that limonene is susceptible to OD processes, as has also been reported for lavandin (Lavandula × intermedia Emeric ex Loisel.). 36 However, the contemporaneous decrease in carvone and limonene in M. spicata var. rubra is not clear and has not been supported by other findings for the related species.…”
