What is Rancidity ? Explain with some examples.
Answers
Answer:
When oxygen molecules interact with the oil and food, the normal structure of the food is damaged, resulting in a change in odour and taste, and it is not recommended for consumption
Explanation:
ex :
when a chips pack is exposed to atmospheric air which results in a change in taste and odour
Answer:
Rancidity is the natural process of decomposition of fats or oils by either hydrolysis or oxidation or both and is often accompanied by unpleasant smell, texture or appearance. Examples of rancidity include the change in taste and smell of potato chips and butter when they are exposed to air for a long time.
Explanation:
Fats and oils react with air and water to produce an unpleasant smell and taste and the process is called rancidity. It is caused due to the conversion of fatty acids esters of oils into free fatty acids.
A common example of rancidity is when a pack of potato chips is exposed to air for a long time which results in a change in taste and odour. A similar thing is observed when butter is exposed to atmospheric air for some time.
Rancidity can be prevented by adding antioxidants to oil, refrigerating, vaccum packing, flushing inert gases in oil foods etc.
