Corrosion vs. Rancidity: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on December 14, 2023
Corrosion is the gradual degradation of metals due to chemical reactions, often with oxygen, while rancidity is the spoilage of fats and oils due to oxidation or microbial processes.

Key Differences

Corrosion involves the deterioration of metals as a result of chemical reactions, typically with environmental oxygen or moisture. Rancidity refers to the spoiling of fats and oils, leading to unpleasant smells and tastes.

The process of corrosion often results in the formation of oxides or other compounds on metal surfaces. Rancidity, on the other hand, results from the breakdown of fatty acids, producing off-flavors and odors.
