So small but so smelly….

This week molecule is butyric acid, a simple molecule that can be found in milk, butter and cheese. Although it can be found in food, this molecule has a characteristic, pungent, acidic smell that (believe me) can easily diffuse.

A small molecular change, however, changes completely the odour of this molecule! The esters of butyric acid, in fact, such as ethyl butyrate have a very pleasant fruity fragrance and are employed in artificial flavouring.
