There’s a lot of information out there about storage life of food items. I thought I’d put it in a couple posts for your reference.
I think the most common storage methods for most of us are canned, and vacuum sealed items. Some people also use food grade storage buckets, along with Mylar inserts and dry ice. Oxygen absorbers are popular too, although they won’t be as effective over time. You can also buy pre-packaged food items in #10 cans that will last for years if unopened. All of these methods are good, dry ice is usually the best, but it’s not that practical for some people, including me.
Frozen Food: Frozen foods should be used within 3 - 6 months for best quality. This isn’t to say that it will be bad for you if you consume something after that, it just won’t taste that good and the nutritional quality would be questionable.
Canned Food: Canned items are usually stamped with an expiration date. Normally canned stuff is good for one year, but it can be okay for longer periods. Items such as meats and low-acidic items will last longer. High acidic items such as tomatoes should be used by the expiration date if possible. If you’re in an extended crisis situation, most items will be okay to consume past the expiration date. Watch for bulging cans - always throw those away, no matter how old they are as they may contain botulism spores. It’s not worth taking a chance.
Water: Plastic bottled water doesn’t have a very long shelf life. The water itself is probably okay, but the plastic in the bottles starts to break down quickly. Always use plastic bottled water by the use by date. My opinion is in an extreme emergency I’d rather drink that than some other contaminated water - but that’s just my choice. There are some people that can water - this is relatively easy and since the jars are glass, you won’t have to worry about plastic contamination. There are also juice box type containers of water you can buy on-line. These will last forever and are a great option for your car and bags.
The following items should be kept in an airtight container, or vacuum sealed for optimal storage.
Baking Soda: 2 years
Beans: 2 years
Cereals: Ready to eat cereals in their sealed boxes will last up to 12 months
Cocoa: Powered cocoa will store indefinitely
Cornmeal: 12 months - Can be frozen indefinitely
Cornstarch: 18 months
Flour: Both white and whole wheat can be stored up to 8 months. Can be frozen indefinitely
Grits: 12 months
Honey: Honey will store indefinitely
Pasta: Regular pasta 2 years - Egg noodles need to be used within 6 months
Rice: White rice will store longer than brown rice in your cupboard, but brown rice has more nutritional value - so, what to do? I store two bags of brown rice that I use in rotation. I also store smaller bags of white rice for long term crisis situations. Brown rice will last if it’s stored in a sealed bag for up to 12 months. White rice will store in a sealed bag for 2 years
Salt: Salt will store indefinitely
Sugar, granulated: 2 years
Rotation is the key to easy long term food storage. Buy items you use and rotate as you use them. It’s useless to stock up on wheat if you have no way to grind it into flour and no way to cook it. Think about easy to prepare foods first and then as your preparations become more developed, you can think of more complex systems of food storage and maybe buy that wheat grinder you’ve always wanted! If you start simple, you’ll be more prepared sooner. You can develop more advanced storage plans when you have some basics ready for an emergency now. Don’t be unprepared because you’re waiting to buy everything you need at once. Our world is so unpredictable, easily accessed food and water are the most important items to consider in the beginning.
If you have any items you’ve been wondering about, post your comment and I’ll list them in tomorrows post.
