What is rancidity ?mention any two ways by which rancidity can be prevented.?

Question

Answer

Food turns rancid when the fats and oils within them get oxidized and the taste and smell of the food changes. Oxidation of fats generates highly reactive molecules in the rancid food which is responsible for the unpleasant odour and flavour. These chemical reactions also reduce the nutrition of the food.
It can be prevented by —>
Adding antioxidants to food.

Storing food in airtight containers to slow the process of rancidification.

Refrigerating food also helps to slow down rancidification.

Replacing oxygen in the containers with another gas.

Answer

*The oxidation of oils or fats in a food resulting into bad smell and bad taste is called rancidity.

*It can be prevented by-

(i) adding anti-oxidants.

(ii) flushing with nitrogen gas.

Answer

When a food containing fats or oils come in contact with air i.e. get oxidized and its taste and smell changes then it is said to be rancid or rancidity..
prevention

Answer

Rancidification is the process of complete or incomplete oxidation or hydrolysis of fats and oils when exposed to air, light, or moisture or by bacterial action, resulting in unpleasant taste and odor.
What is rancidity give example?

The condition produced by aerial oxidation of fats and oils in food marked by unpleasant smell and taste is called Rancidity. For Example, Potato Chips when kept in air for a long time gives unpleasant smell and bad tast

There are three types of rancidity :

Hydrolic rancidity: it occurs when water splits fatty acid chains away from the glycerol backbone in glycerides.

Oxidative rancidity: it occurs when the double bonds of an unsaturated fatty acid react chemically with oxygen

Answer

Rancidity is the oxidation of foods containing fats and oils. 1) Rancidity can be prevented by storing food in vacuum containers. 2) Rancidity can be prevented by adding antioxidants to food

Answer

Spoilage of food in the way that it becomes smelling bad is called rancidity. methods to prevent it.....
1. Use of oils ( preservatives )....
2 Keep food in refigirator....
3.Vacuum packing

Answer

Food become rancid when it is kept open so that the food get oxidized to change the taste and smell of the food.
Preventive measures are
•By adding antioxidants
•By storing in a air tight container .

Answer

Rancidity:
Rancidity is the process where fats and oils undergo oxidation, leading to the development of unpleasant odors and flavors. This can occur in various food products, causing them to spoil and become inedible.

Prevention of Rancidity:

1. Antioxidants:
Adding antioxidants to fats and oils can prevent rancidity by inhibiting the oxidation process. Common antioxidants used in food preservation include vitamin E, vitamin C, and synthetic antioxidants like BHA and BHT. These compounds work by scavenging free radicals that initiate the oxidation of fats and oils.

2. Proper Storage:
Proper storage can also help prevent rancidity in fats and oils. Keeping these products away from light, heat, and oxygen can slow down the oxidation process. Storing fats and oils in airtight containers in a cool, dark place can help maintain their freshness and prevent rancidity.

By implementing these preventive measures, the development of rancidity in fats and oils can be minimized, ensuring the quality and safety of food products for consumption.
