" Which type of packaging method is used for extending the life of food products by changing the atmosphere surrounding the food inside the package?

Correct option is C

Modified Atmospheric Packaging (MAP) is a method used to extend the shelf life of food products by altering the atmosphere inside the package. This is done by modifying the levels of gases such as oxygen, carbon dioxide, and nitrogen that surround the food. The primary goal of MAP is to slow down the respiration rate of fresh produce or reduce the growth of spoilage organisms like bacteria and mold, thereby maintaining freshness and extending the food’s shelf life.
· For example, in packaging for fruits, vegetables, or meats, reducing oxygen and increasing carbon dioxide can slow down spoilage​​.
Information Booster:
Modified Atmospheric Packaging is commonly used for perishable products such as fresh meat, seafood, fruits, vegetables, and bakery products. The technique is used extensively in the food industry to keep products fresh for a longer period without the use of preservatives.
· Benefits:
· Extends the product's freshness.
· Reduces the need for artificial preservatives.
· Retains the natural color and texture of the food.
· Reduces the growth of spoilage microorganisms.
Additional Knowledge:
· (a) Aseptic Packaging: Involves sterilizing both the food and the packaging separately and then combining them in a sterile environment. Commonly used for long-life milk and juices​.
· (b) Shrink Wrap Packaging: Involves wrapping food items in a plastic film that shrinks tightly when heat is applied. It is mainly used for protection rather than for changing the atmosphere around the food​.
· (d) CPET Packaging: Refers to Crystallized Polyethylene Terephthalate, a type of packaging material often used for ready meals that can be heated in the oven or microwave, but it does not modify the internal atmosphere​.
