Among the following organic acids, the acid present in rancid butter is:
1) pyruvic acid
2) lactic acid
3) butyric acid
4) acetic acid
The correct answer is butyric acid
The organic acid present in rancid butter is butyric acid.
Rancidity is the spoilage of fats and oils that occurs due to the breakdown of their components. When fats and oils are exposed to air and light, they undergo oxidation, which leads to the production of various compounds, including organic acids.
Out of the given options, butyric acid is the most commonly found organic acid in rancid butter. It is a four-carbon fatty acid that has a pungent, rancid odor. Butyric acid is produced by the bacterial fermentation of milk sugar, and it is also present in the digestive tract of animals.
