Lemon essential oil is extracted from the peel of lemon fruit by cold pressing. There are many cells that secrete essential oil in lemon peel. Cell membranes can be destroyed by external forces, and essential oils can seep out. There are many methods of extrusion, and the most traditional one is the most destructive to the essence. When pressing, the peel is pressed with a sponge, and the generated essential oil can be absorbed by the sponge, and then the peel is discarded, and the rough roll of lemon essential oil can be obtained by pressing the sponge. After simple impurity removal operations such as filtration, very high quality lemon essential oil can be obtained. If lemons are grown organically, almost perfect organic lemon essential oil can be obtained.
