FAQs on Fun Video: Rancidity Video Lecture - Class 10
| 1. What is rancidity? |  |
Ans. Rancidity refers to the development of unpleasant odors and flavors in food products due to the decomposition of fats and oils. It occurs when the fats and oils undergo oxidation, leading to the formation of rancid compounds.
| 2. How does rancidity occur? | |
Ans. Rancidity occurs through two main processes: hydrolytic rancidity and oxidative rancidity. Hydrolytic rancidity happens when fats and oils react with water molecules, leading to the breakdown of triglycerides into free fatty acids. On the other hand, oxidative rancidity occurs when fats and oils react with oxygen in the air, resulting in the formation of free radicals and the oxidation of fatty acids.
| 3. What are the factors that contribute to rancidity? | |
Ans. Several factors contribute to rancidity, including exposure to air, high temperatures, light, moisture, and the presence of catalysts such as metals. These factors accelerate the oxidation or hydrolysis processes, leading to the development of rancidity in food products.
| 4. How can rancidity be prevented? | |
Ans. Rancidity can be prevented by storing food products in airtight containers to minimize exposure to oxygen. Refrigeration or freezing can slow down the oxidation process. Additionally, adding antioxidants such as vitamin E or using packaging materials that block light can help prevent rancidity.
| 5. What are the health risks associated with consuming rancid food? | |
Ans. Consuming rancid food may pose health risks as it can lead to the ingestion of harmful compounds. Rancid fats and oils can contain free radicals and oxidation products, which can contribute to oxidative stress and inflammation in the body. This can potentially increase the risk of various diseases, including cardiovascular problems and certain types of cancer.

Topic: Rancidity.
Why is a bag of chips half full?
Looks like you don't believe me.
Open the bag.
See I told you.
The bag of chips is indeed half full.
Why is that so?
It is mainly because of a concept called rancidity.
When food becomes rancid, it develops an unpleasant smell and taste and it becomes unsafe for consumption.
Rancidity generally refers to a condition
where the fats and oils present in food get oxidized.
Resulting in food spoilage.
Since the chips contain fats and oils, they
are likely to get rancid.
Therefore, to prevent this, nitrogen gas is
flushed into bags of chips by manufacturers.
But, why nitrogen?
Nitrogen does not react with fats and oils.
As a result, rancidity does not take place.
Moreover, a gas in the bag serves as a cushioning agent and prevents the chips from crumbling.
That is why the bag of chips is only filled
till half.
