...some very phenolic compounds are used as replacemants in cases, such as the soaps, where vanillin cannot be used because it rapidly turns chocolate-brown (查看原文)
Natural vanilla extract contains lots of phenolic notes, and smells a bit like a fresh exotic-fibre carpet or smoky, wet tea leaves. This is desirable, because pure vanillin is a little too clean all by itself, and needs a bit of phenolic raunch to perform at its best in perfume. Indeed, when Jacques Guerlain used vanillin in fragrances, he always choose a somewhat impure grade which smelled nicer (the firm of De Laire sold it to ihim for more than the pure stuff). He then mixed, say, ten parts of this stuff to one of the expensive vanilla absolute to make it both cheap and rich. (查看原文)

原本只想了解一下嗅觉的分子振动理论，意外地被LT对学术圈的评论戳中，比如“如今大学就是生意，实验空间的每一个平方米都得用来赚钱”，“Nature当然能成就事业，但也可能毁掉事业”。
