We’ve all seen puffed-up chip bags or bloated cheese containers, but not all bloating is bad.
In many cases, extra air is added to packaging to protect food.
For instance, chip bags are filled with nitrogen to prevent crushing, while vacuum-sealed packages for perishable items like cheese and meats help stop bacterial growth by removing oxygen.
However, unusual bloating in items like dairy, meats, or canned goods may indicate spoilage.
Be cautious with any bloated package: check expiration dates, avoid buying visibly bloated perishables, and trust your instincts if something seems off.
Understanding the reasons behind different packaging methods helps you make safer choices when grocery shopping.
