Question

The system that detects or senses changes within the package environment, followed by modification of package properties in response to the detected change is known as

• A. Aseptic Packaging
• B. Passive Packaging
• C. Active Packaging
• D. Intelligent Packaging

Hint:

Remember the difference: \textbf{Active} packaging {acts} on the food (e.g., removes oxygen). \textbf{Intelligent} packaging {informs} about the food (e.g., changes color if spoiled).

Answer 1

The Correct Option is D

Step 1: Define the different types of packaging.
Passive Packaging: This is a traditional packaging that simply provides a barrier to protect the food from the external environment (e.g., a simple plastic bag or glass jar).
Active Packaging: This type of packaging interacts with the food or the headspace to improve quality or safety. Examples include oxygen scavengers, moisture absorbers, and antimicrobial films.
Intelligent Packaging: This type of packaging monitors the condition of the packaged food or the environment inside the package and communicates this information. It involves sensing, detecting, and informing. Examples include time-temperature indicators and freshness sensors. The question describes a system that "detects or senses changes," which is the core function of intelligent packaging.
