Question

Examples of active packaging includes;
(A). MAP
(B). Ethylene scavenger
(C). Antioxidant release film
(D). Moisture absorbents
Choose the most appropriate answer from the options given below:

• A. (A), (B) and (D) only
• B. (A), (B) and (C) only
• C. (A), (B), (C) and (D)
• D. (B), (C) and (D) only

Hint:

The key to identifying active packaging is to look for an ongoing "action" word: scavenging, absorbing, releasing, or emitting. MAP is a one-time "modification" of the atmosphere, making it distinct.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Active packaging refers to systems where the package, the food, and the environment interact in a way that extends shelf life or improves product quality. This goes beyond the passive barrier function of traditional packaging. It involves components that actively scavenge, absorb, or release substances within the package.
Step 3: Detailed Explanation:
- (B) Ethylene scavenger: This is a classic example of active packaging. A sachet or film actively absorbs ethylene gas produced by fruits and vegetables, thereby slowing down the ripening and senescence processes.
- (C) Antioxidant release film: This is an active system where the packaging material is impregnated with an antioxidant (like BHT or vitamin E) that actively migrates into the food to prevent oxidative rancidity.
- (D) Moisture absorbents: Also known as desiccants, these are sachets or pads that actively absorb excess moisture from the headspace or from the food product (e.g., in a package of fresh meat), inhibiting microbial growth.
- (A) MAP (Modified Atmosphere Packaging): This is a closely related but distinct technology. In MAP, the air in the package is replaced with a specific gas mixture at the moment of packaging. The package then provides a passive barrier to maintain this atmosphere. It does not involve a component that is continuously and actively changing the atmosphere over time. Therefore, it is generally classified separately from active packaging.
Step 4: Final Answer:
Ethylene scavengers, antioxidant release films, and moisture absorbents are all clear examples of active packaging. Therefore, option (D) is the most appropriate answer.
