Aldehydes is urs answer. ... ....
Answer:
Among the following, aldehydes and ketones are majorly responsible for rancidity.
Explanation:
Rancidity is the process that takes place in fats. It leads to bad odour and bad taste in fats
it is due to the exposure of these fats to high heat and high humidity.
When fats react with oxygen or undergo oxidation, they lead to the formation of aldehydes or ketones.
Rancidity can also occur due to microorganisms and physical factors.
It takes place in three steps,
Initiation: involves the formation of radicals(an atom with an unpaired electron) because of various external factors
Propagation: It involves the reaction of radicals with atmospheric oxygen which leads to the formation of peroxides.
These peroxides give rise to more and more radicals.
Termination: When two radicals combine, they give rise to end products that are aldehydes and ketones.
