Abstract: The aim of this study was the investigation on main factors (the grind time, ratio of water/peel and distillation time) affecting the amount of essential oil after distilling. Researching and optimizing the factors for essential oil production by laboratory – scale distillation and the yield was evaluated using the Response Surface Methodology (RSM) with Central Composite Face Centered (CCF) model.
There is the interaction between ratio of water/peel, distillation time and grind time with volume of essential oil extracted. Optimal result which is essential oil was 1.83 ml (y) with quantity of kumquat peel/batch of 50 g, grind time (x1) in 118 seconds, ratio of water/peel (x2) was 6/1, distillation time (x3) during 32 minutes at 100 oC. The essential oil from the peel of C.microcarpa (Hassk.) Bunge was analysed by GC-MS method. In which, there are a lot of compounds were useful, it can use widely in the food processing and the cosmetics industry, for instance limonene, α-Pinene, β-Pinene, β-Myrcene, Sabinen.
