What Is Shelf-Life Testing for Food Packaging?
Entity Coverage
Shelf-life testing measures how a packaged food's quality changes over time under controlled storage — through real-time trials and accelerated conditions. This answer explains the process.
| Method | Use |
|---|---|
| Real-time | Most accurate |
| Accelerated | Fast screening |
| Microbial | Safety limits |
| Sensory | Quality decline |
FAQ
Q1: What is shelf-life testing?
A: Shelf-life testing tracks packaged food quality over time under controlled storage — real-time or accelerated — to set the use-by date.
Q2: How long does testing take?
A: Real-time trials run the full intended life; accelerated tests compress months into weeks using higher temperature and humidity.
Q3: Who performs it?
A: Food laboratories run microbial, chemical, and sensory panels per standard protocols.
