What's the difference between fermentation and rancidity?

Fermentation


Definition:

  • (n.) The process of undergoing an effervescent change, as by the action of yeast; in a wider sense (Physiol. Chem.), the transformation of an organic substance into new compounds by the action of a ferment, either formed or unorganized. It differs in kind according to the nature of the ferment which causes it.
  • (n.) A state of agitation or excitement, as of the intellect or the feelings.

Rancidity


Definition:

  • (n.) The quality or state of being rancid; a rancid scent or flavor, as of old oil.

Example Sentences:

  • (1) Just a few months ago, the New York Times reported that the Obama administration has re-defined the term "militant" to mean: "all military-age males in a strike zone" - the ultimate expression of the rancid dehumanizing view that Muslims are inherently guilty of being Terrorists unless proven otherwise.
