Process
a. Distillation
The eucalyptus leaves are put into an alembic (distillation apparatus) over water. As the water is heated, the steam passes through the plant material, vaporizing the volatile compounds. The vapors flow through a coil, where they condense back to liquid, which is then collected in the receiving vessel.
b. Expression
The citrus peels are expressed mechanically, or cold pressed (similar to olive oil extraction).
c. Solvent extraction
Most flowers contain too little volatile oil to undergo expression and their chemical components are too delicate and easily denatured by the high heat used in steam distillation. Instead, a solvent such as hexane or supercritical carbon dioxide is used to extract the oils.

Interesting product you made today. Also, the solvent extraction of oil from flowers is most interesting technique of extraction.
ReplyDeleteI have one experience. From my travel in Perth some time ago, I discovered the paperback trees. When I went back to Malaysia I found the same trees here. The scientific name of the tree is Melaleuca sp. By distillation, transparent oil could be extracted from the leaves of the tree. The oil smell like mint. It is highly effective topical antibacterial and antifungal.
That is most interesting!
ReplyDeleteI have a sneaking suspicion the tree in front of the house is a paperback tree. I remember the stories of your travels every time I look at it.
The tree in front of the house might well be a paperbark tree [it's paperbark not paperback - my mistake :)] if the bark of the tree looks like sheets of paper only that it is light brownish and lignified.
ReplyDeleteBTW, true to what you've said, you're improving the blog presentations by the day. Now, you put in pictures of your products! Hope this won't be a wiki for products blog :).
