How to Store Your Food So It Lasts Longer

On average, American families trash 14% of the food they buy, often because it spoils.

On average, American families trash 14% of the food they buy, often because it spoils. But you can extend the life of groceries with these easy storage tricks:

  • Organize fruits and veggies: We often toss produce into crispers together, but apples and some other fruits give off gas called ethylene that speeds ripening in vegetables. So store them separate, so vegetables don’t ripen too fast
  • Know which need room temperature: We tend to keep most of our fruits and vegetables in the refrigerator. But cold temperatures can actually damage some produce, like squash, tomatoes and oranges
  • Use your own packaging: That flimsy package from the butcher won’t protect your meat from freezer burn. Put it in a vacuum sealed or sip lock bag with the air squeezed out
  • Protect your dry goods: Dry kitchen products like flour, cornmeal and other grains can attract bugs that make them unusable. Instead, stash them in the refrigerator or the freezer where they will be safe from pests
  • Chill your bananas: Most of us keep our bananas on the kitchen counter. But it seems like they spoil almost as soon as they ripen. Instead, store them in your refrigerator once they have ripened. The skin will turn brown but the inside lasts a lot longer
  • Shield leftovers from the air: Many of us end up throwing out leftovers because they went bad. To prevent it, don’t just cover the top of the bowl with foil or plastic wrap. Instead, transfer your leftovers to an airtight food storage container to keep them fresh

So keep it fresh longer. Oxygen damages food, so air tight packaging will help keep things fresh.

in addition to placing leftovers in an airtight container which really just limits new air from getting in, is to place plastic wrap directly on top of the food to minimize air contact then place the lid. It helps my guacamole last twice as long.

So many products you buy promise great things without follow-though, but I find that the plastic "lettuce savers" really do extend the life of heads of lettuce. Bread keepers are pretty good, too.

I disagree somewhat about the oranges and tomatoes.

I tried keeping oranges in a cabinet, and they went moldy in less than a week. I've also had oranges I picked myself fresh from the tree (visiting near San Jose, CA) and they didn't taste any better than store oranges.

Refrigerating tomatoes doesn't damage them and does keep them longer. Most store tomatoes have been refrigerated. But refrigeration does change the taste. Get a couple of tomatoes from a neighbor who grows them. Put one in the fridge overnight. The next day, take it out and let it get to room temperature. Now taste both tomatoes. There is a noticeable difference.

You're absolutely right about the bananas. I've told this to many people, but no one believes it. :)

I like to store my cat in the refrigerator.
#5 by cool runnin, Sep 7, 2007
Hi Ibod Catooga!

Actually your cat will stay fresh much longer if you leave it on the sofa. Try storing your brain in the "chill" section of the fridge though, if you can find a container small enough to put it in.
Good luck to you.

Lots of good ideas. Also when you scoop a spoon into a container for a dollop of something out of the fridge (yogurt, miso), make sure the spoon is clean. Otherwise, whatever food residue you introduce to the container will make that food go bad much faster.

No one ever mentions this, but I will..

Keep your fridge at 37 degrees - it'll make all your food last a really long time. Especially produce. Most people think that turning the temp up will save money on electricity. Yeah, maybe 1-2 bucks a month. But, you are throwing away lettuce probably 5 days before it needs to be thrown away. That's the worst one...lettuce. But, count all the other food that spoils quickly and see how much cash you throw out. I used to keep the temp up and always threw away food. But, someone told me to keep it at 37 degrees and now I'll always do it. The food tastes better too.

If you eat all your food, you don't have the worry of storing it!
#10 by Anji, Sep 15, 2007
Christopher, I hope you mean 37 degrees Fahrenheit! When I first read your comment I thought you meant 37 degrees Celsius - human body temperature!

Your tip on Protecting dry goods is nearly worthless. Storing huge bags of flour, rice, beans, cornmeal, or other staples in the refrigerator is not only wasting space and energy, but severely limiting your available storage space for dry goods. If pests are the problem, please find a solution to the pests, rather than simply holding to "put them in the fridge" as a catch all solution. Perhaps then you'd have advice that would be useful outside of our own wasteful country. What about people who cannot afford / choose to live without a fridge/freezer? That's most of the world, so you know.
#12 by J.Martin, Sep 15, 2007
To Ace Pincter for the comment. To each his own. My refrigerator is on and running even if I did not store these items in it so that my other food will not spoil. So I do not feel that I am waisting energy. I do not know of anyone in this day and time that does not have some type of refrigerator in their home.
#13 by B.Boynton, Sep 15, 2007
where are you hiding your compassionate brain. There are millions of folks that do not have refrigerators or freezers or even food to worry about keeping. Just because you are lucky enough to have these things does not mean everyone is.
#14 by Mrs L, Sep 15, 2007
I imagine the people without refrigerators are not online looking for food storage tips.
#15 by Lunatunes, Sep 15, 2007
Keeping your whole grain flour in the freezer will actually extend the life of the flour, which can go rancid eventually due to the oils in the grains. Also, the brown flour moths that will eventually infest your pantry if you leave your flour out come with the flour from the refinery as eggs, so keeping it in the freezer prevents the little suckers from maturing. Do sift your flour.

Actually, the best way to preserve food is to buy only as much as you need and to prepare only as much as you'll eat. Don't get me wrong, I like Americans, but the truth is they are hopeless consumers (not my thought, but generally true), and that is the real source of these kinds of problems... You won't see anyone in Romania arriving home with an SUV full of food (most of which he/she wouldn't need anyway).
I agree with most of the tips though; thanks for posting them.

And yes, we do have fridges/freezers here in Romania...
#17 by Mr L, Sep 16, 2007
I agree with Mrs L, although no, she is not my wife or relative.

Those without refrigerators will not be looking online, and most of those tips work just as well for a cold storage room (Larder in England).

Good day all.

Mushrooms should not be stored in plastic - paper bags are better.

You can buy vegetable storage zip-lock bags with little perforations to vent moisture. These keep my greens lasting longer. Maybe this is what the earlier poster meant by lettuce storage bags.

I have a few tips:
1. Buy only the food you'll eat
2. Eat the food that you bought

The bananas keep better in the fridge when wraped in Bubble wrap, they stay yellow and the inside stays clean, also they taste even better.

Agree about the need to store carefully but ethylene is a gas purposely used to give fruits that ripened look and to my knowledge is not emitted by the fruit.
#22 by sianz, Sep 27, 2007
i'm appalled that some people never figured out the economies of scale when it comes to buying certain things in bulk.

#23 by botanist, Oct 4, 2007
Ethylene is given off by fruit, as well as other plant parts that are reaching the end of their lifespan. The food industry exposes fruits to ethylene to encourage ripening (or at least the appearance of ripening).
#24 by dormgirl88, Oct 6, 2007
To Liza, #22.

"1. Buy only the food you'll eat
2. Eat the food that you bought"

That works, unless you are in a small dorm room with no refridgeration, the dining plan you are required to sign up for is way out of line, and you can't buy your bread and jam two servings at a time.

Still trying to eat and not waste.

does anyone know how long watermelon keeps when its not in the fridge?
and what about if its only the rind, and is covered in white glue??
#26 by chela, Oct 25, 2007
just for the record: food preservation is an ancient practice. some techniques: covering in salt, oil or vinegar, smoking, dehidrating... in "civilized" countries nowadays these techniques sound more like "fancy cooking" and not "preservation" but they are still used in many countries and won't ever be obsolete...

and yes, i agree with #14 by B.Boynton: millions of people on this planet don't have to worry about food preservation because they happen to have NO FOOD...
let's consider ourselves fortunate and don't waste.

i've really enjoyed this conversation panel
thank you all for sharing.

@ Ace Pincter #12:

Actually, the more stuff you have in your refrigerator, the better. Filling it up saves energy rather than wasting it.

Tomatoes, bananas, and apples will ripen faster in the presence of ethylene. Bananas placed next to other fruits will produce enough ethylene to cause accelerated fruit ripening. Ethylene will shorten the shelf life of cut flowers and potted plants.

Dry goods do well in those locking plastic containers that have four locking tabs and rubber gaskets.

Rebecca makes a good point about more cold mass in the fridge means the fridge works less to keep it cool. I use beer bottles instead :) Also, I keep my fridge at a chilly 32F, just enough that most stuff won't freeze...barely.

Fridge thermometer is one of four essential kitchen thermometers, the others being oven thermometer, quick-read digital and roasting/timing with probe.

Question for #20 Andrew M...
Where can you can buy vegetable storage zip-lock bags with little perforations? I have not been able to find them???
#31 by Babs, Dec 29, 2007
to #33. if you can't find perforated bags, make some. Here's how...
Step 1. Remove new ziploc bag from dispenser
Step 2. Pick up clean fork with right hand (left if you are left-handed)
Step 3. Grasp Baggie with other hand
Step 4. Carefully use fork to poke holes in Baggie.
Step 5. Repeat step 4 until desired number of holes have been made.

Alternate methods: Use scissors to snip little holes. You can fold the baggie like an accordian and cut mulitple holes at once. Much more efficient than previous method, but requires some dexterity and origami skills. :-)

Hey Babs, You are hillarious. I cracked up reading your comment.
I like the comments. informative and occasionally funny..:)

" What about people who cannot afford / choose to live without a fridge/freezer? That's most of the world, so you know."

I'm sure they're checking the Internet for tips on how to store their food.
#34 by carlene, Jan 27, 2008
The bananas in the fridge is a great idea . Ive done it for years. But i recently found out that if the bananas are together in a bunch they will ripen more quickly. But if you seperate each banana it will not ripen as fast. Give it a try and see.
#35 by Katie, Feb 6, 2008
Try 1 or 2 whole bay leaves right in the flour or beans. It won\'t change the flavor of the food, and keeps beetles away very well.
#36 by Justin, Mar 7, 2008
Considering that everyone seems to think that there are no fridgeless people online, I\'ll give some of the tips that I know:
1. Most food is already well preserved straight from the store, it\'s been sitting on those shelves for weeks after all. Fruit, condiments, and dry goods need no special storage at all (besides a cool, dark cupboard), if they\'re eaten in a reasonable amount of time (a week or so for fruit, a month or so for condiments). Eggs and yogurt will also last at least a week out of the fridge.
2. Well-cooked food is sterile. Immediately putting it in an airtight container will prevent spoilage for quite a while. If it\'s something that\'s used in portions, always use a clean utensil to remove it. This applies to many goods in jars as well, such as jelly (and I hear even mayonnaise!).
3. Refrigeration and freezing are only one set of methods for food preservation. Others, which are too involved to describe in a comment are: fermentation, pickling, drying/smoking, canning, and salting/sugaring.

And of course the best advice is to not need to store it at all! Buy only what you need for a week, eat leftovers the next day, and plan your meals based on what you have at hand to use up.
