Comparison volume of essential oils of fresh and dried kaffir lime leaves from the distillation of essential oils with a 30 liter distiller

Abstract

This research presents a comparative experiment on the quantity of essential oil distilled from fresh and dried kaffir lime leaves. The essential oil was distilled from a 30 liter distiller, using raw kaffir lime leaves from the planted area in Phang Khon District, Sakon Nakhon Province. Methods of the study by preparing raw materials are: Fresh kaffir lime leaves, chopped fresh kaffir lime leaves and dried kaffir lime leaves make an essential oil distillation, compare the amount of essential oil. Distilled fresh kaffir lime leaves and chopped fresh kaffir lime leaves 3 kg/Batch and dried kaffir lime leaves 1 kg/Batch, inside the distiller add 10 liters of water, distillation time 2 hours, vapor temperature is 100 °C. Condensing water temperature
10-15 °C controlled throughout the essential oil distillation period. The experiment was repeated in each of the 3 trials for a total of 9 trials. To collect the amount of essential oil extracted from different raw materials and present the experimental data in the form. Percentage of essential oils distilled from different raw materials. From the experimental results, it was found that the amount of essential oil distilled from fresh kaffir lime leaves had an average oil volume of 28.16 ml, followed by chopped fresh kaffir lime leaves had the average oil volume is 23.83 ml. and dried kaffir lime leaves will have the least amount average oil content is 5.46 ml. When considering the percentage of essential oils. From the experimental found that fresh kaffir lime leaves 2.56 %v_oil/w_dry and 2.18 %w_oil/w_dry, chopped kaffir lime leaves with percentage of distilled kaffir lime leaves 2.20 %v_oil/w_dry and 1.94 %w_oil/w_dry. Finally, dried kaffir lime leaves. The least amount of essential oil was 0.49 %v_oil/w_dry and 0.41 %w_oil/w_dry. When considered, it was found that fresh kaffir lime leaves were chopped and distilled, the amount of essential oil was decreased by 15.28%. And when fresh kaffir lime leaves were dried before being used for essential oil distillation, it was found that the essential oil from dried kaffir lime leaves was decreased by 75.98%.
