Question

vanilla essence odour?

Answer 1

Pour a little vanilla extract in a bowl and microwave on High for one minute. Now, that's better. If you would rather not have the unpleasant smell of fresh paint in your house, mix 1 tablespoon vanilla extract into the paint can when you open it.

Answer 2

Vanilla extract has a characteristic pleasant smell. If a basic solution like sodium hydroxide solution is added to vanilla extract then we cannot detect the characteristic smell of vanilla extract. An acidic solution like hydrochloric acid, however, does not destroy the smell of vanilla extract.
