Wish your groceries lasted a few more days? Grocery shopping can be frustrating, especially if you love fresh produce and other perishables. In addition, certain foods, for instance, bananas and bread, have a brief shelf life. So, you’re forced to buy in smaller portions. But that’s ok because instead of wasting time, money, and gas on shopping, here are some ways to make your groceries last longer so you can shop less.

1. Use Mason Jars
   With glass Mason jars, you won’t have to worry about being exposed to BPA that may be in some plastic containers. Also, mason jars do not stain, and many people believe that produce lasts a few days longer. The best part is that you can find them almost anywhere and online.
2. Shrink-wrap the crown of bananas
   It only takes a few seconds to secure some plastic wrap around the crown of a bunch of bananas. This curbs the release of ethylene gas and thus making your bananas last longer.
3. Wrap greens in foil
   When wrapped in foil, broccoli, lettuce, and celery can last in the fridge for a month or more.
4. Stabilize the refrigerator’s temperature
   Aim for 40 degrees Fahrenheit to prevent the growth of toxic food bacteria. You don’t want the temperature so cold that your food freezes. A refrigerator that is too warm encourages spoilage, and that’s throwing money away.
5. Place tomatoes upside down on the counter
   If the stem is removed before purchase, place the tomatoes upside down so air won’t seep into the small opening, expediting ripening.
6. Store milk away from the refrigerator door
   The temperature is cooler on the middle shelf of a refrigerator. That’s the place to store things that could spoil quickly.
7. Segregate produce and meats
   Allowing fresh produce and meats to mingle creates the risk of cross-contamination and causes rapid spoilage.
   Meats should be wrapped and stored near the bottom of the refrigerator or freezer (if they leak). To be safer, place meats in a bowl to catch any liquid.
8. Store leftovers in airtight glass containers
   Airtight lids keep air out. And with glass, you don’t have to worry about chemicals from plastic leaching into your food.
