Rosemary Oil Extraction Process
What You Need for the Rosemary Oil Extraction Process:
– EssenExTM 100 Distillation Kit for Rosemary oil distillation.
– 100 grams of Rosemary, chopped or ground.
– Place Rosemary in Freezer for 24 hours.
– For initial runs, use 100 grams. Later, more or less may be used.
– Add water with ratio ¼ to ½ ml water per gram of botanical. ( ¼ to ½ :1 by mass)
– Place in EssenExTM as described in user manual.
– Place the reactor into the microwave with mug of water.
If multiple batches are run, change water in the mug between trials.
– Each batch should run for 6.25 minutes on a power setting of HIGH (1100 watts)
Lower power units: simply add 30 seconds to a minute for the cooking phase.
– Allow the batch to cool for 6 minutes. In or outside the microwave. Caution: do not raise lid prior to 4 minutes and be careful if moving from microwave as jar will be quite warm initially.
This is a key step to your success. Cooling allows the vapors to condense and form more oil and it allows the reactor to be handled much easier!
– Pour top contents of the beaker into the easy separator and rotate it using the palms of your hands while resting it on a cloth (kitchen towel) on a hard surface (counter top). The motion should be similar to starting a fire with sticks.
– After a few seconds, stop rotating the separator and observe the oil layer.
– Repeat the process if you believe more oil will collect.
– Once the oil is separated (above the hydrosol in the neck of the flask), use the pipette to place it in a vial.
– Upon lifting the lid, a small amount of ice should be remaining on screw.
If not, then reduce the amount of water added.
– With nominally good Rosemary, 0.4 to 0.6 % by mass.
100 grams yields roughly 0.5 to 0.7 ml oil.
