谁给介绍一下如何在家里自己提炼精油,例如后院的玫瑰花,如何从花瓣里提取出香味来? ...
我给你介绍一下,如果要提炼1盎司的玫瑰精油,你先准备4500公斤的玫瑰花瓣。等几卡车的玫瑰花瓣卸下以后,按照下面步骤就可以了。
Instruction
1. Pick enough roses to fill your kettle loosely. Gently cut or pluck the petals from the roses.
2. Put smooth river stones at the bottom of the kettle; this keeps the botanicals from scorching on the bottom of the kettle. Fill, but do not pack, the kettle full of rose petals, and gently crush them.
3. Use spring or distilled water to cover the rose petals.
4. On a counter next to the stove top, use a cake stand or overturned pot to elevate a bowl to the same level as the teapot spout.
5. Fill the bowl with ice water.
6. Place a jar next to the raised ice-water bowl so that the ice-water bowl is between the jar and the stove top. Ideally this jar, called the "receiver," will sit a little lower than the ice-water bowl.
7. Attach the plastic tubing to the end of the teapot spout, and put its other end in the receiver. The tube's middle section must rest in the bowl of ice water.
8. Cover the kettle, boil the water and then turn the burner to low. Continue simmering until the water in the pot reduces by half. This may take several hours, depending on the size of the kettle.
9. Examine your receiver. It should have collected up to a pint of the condensed droplets of the vaporized steam from the kettle. This is your rosewater, and can be used as is or further separated into rose hydrosol and essential oil.
10. To collect the essential oil, place the receiver jar into the freezer. The liquid part of the hydrosol will freeze while the essential oil will remain liquid and separate.
11. Pour the unfrozen part of the mixture, the essential oil, into a small vial and store in a cool, dark place.
