Re: [問題]如何分辨精油真假

[laurentV (Laurent V.)]

前文束刪

看到一個測驗的方法
http://www.crunchybetty.com/21-things-you-should-know-about-essential-oils

To test your essential oil to see how “pure” it is, put a single drop of it
on a piece of construction paper. If it evaporates quickly and leaves no
noticeable ring, it is pure. If you have a ring left, then it is likely
diluted by the manufacturer with an oil of some sort (this test will not work
for myrrh, patchouli, and absolutes).

真的嘛？-_-
請高人指點了

推 chromate    :這只能測是否有混植物油而已，而且原文有說了有例外
→ Voglia      :(此判別法不適用於沒藥、廣藿香和原精)
→ Voglia      :這算是簡易判別法　市面上有很多號稱純精油的其實看
→ Voglia      :使用說明就可以知道是按摩油　水蒸餾法萃出的精油
→ Voglia      :可以用這作基礎的判別　但這不是一種精確的檢驗方式
