what is rancidity mention two methods to prevent it
Rancidity is the process in which oils and fats get oxidised after long exposure to air, light, or moisture, causing food to develop a bad smell and unpleasant taste.
Foods containing fats and oils, such as chips, butter, and fried items, become rancid if stored for a long time.
Causes of rancidity
Exposure to oxygen
Heat and sunlight
Moisture in the air
Two methods to prevent rancidity
Store food in airtight containers
Airtight packing reduces contact with oxygen and slows down oxidation.
Keep food refrigerated or in a cool place
Low temperature slows the process of oxidation and helps preserve food for a longer time.
Other common prevention methods
Using nitrogen gas in food packets
Adding antioxidants to food
Keeping food away from sunlight
Preventing rancidity helps maintain the taste, smell, and quality of food products.
