MOLT: The Enemies of Long Term Food Storage

One of the most frequent questions I get asked is how long food will store if using Mylar Bags and Oxygen Absorbers.  I don’t try to be evasive, but sometimes I can’t come right out and say a specific period of time, whether that will be 1, 5, 10, 20 or even 30 years, which is the claim that many survival and preparedness sites use as the longest food will store.  The reason is that there are multiple factors that go into whether your food will store poorly or well long term, and the packaging is just one piece of it.  I definitely don’t want my families livelihood or another families survival threatened if I say ‘yes, your food will store 5 years’ and then 5 years from now someone opens their food and find it is spoiled because they stored it in their garage which is 110 degrees in the summer and -10 in the winter, they didn’t seal the bags properly, and they stored food with 25% moisture content.

Here is what I will say:  there have been studies of food storage methods done by the LDS and others that indicate some foods can be stored up to 30 years or more.  What that means is that the food retains its nutritional and caloric value, but might still have some taste and palatability issues.  However, please be aware that most of these studies are for the standard practice of the LDS Church of using #10 cans in their food storage.  You might find it funny for a supplier of Mylar and O2 absorbers to recommend #10 can sealing.  Mostly I want to provide the best information I can, and there is no doubt that #10 can sealing is the best way to store food long term…if you have access to a sealer and a supply of #10 cans.  The challenge is can sealing is VERY expensive.  To store the same 400 pounds of food that a standard Mylar Bag combo kit can, it would take approximately 80 #10 cans.  Even if you add in the cost of buckets, it would cost the average person $80.00 or so to store using Mylar and buckets, but over $400 using #10 cans.  That’s a pretty huge difference if you are trying to take care of your financial resources.  If you have access to an LDS cannery, you can get cans much cheaper, but even so it would cost 50-100% more to store using cans.

So yes, I recommend #10 can sealing if you can afford it and have access to the tools needed, but I recommend Mylar and bucket storage as the next best thing for the rest of us.  A properly sealed Mylar bag stored with an oxygen absorber inside a bucket mimics the most important properties of the #10 can system:  oxygen elimination and light control inside a rigid barrier to protect from rodents or insects.  The other two properties that most effect your long-term food storage and temperature and moisture. 

Because I had a hard time remembering the four main enemies of food storage, I came up with the acronym MOLT.  It stands for Moisture, Oxygen, Light and Temperature, and it helps me keep focused on mitigating each of them when our family stores food.  Sometimes I include ‘Time’ as a fifth enemy, but it is really just that the other 4 do damage…over time.  Let’s take a brief look at each.

Moisture is probably the most difficult of the factors affecting your food storage, mainly because it is a byproduct of our environment and where we live, as well as a component of the actual food.  Unless you live in a desert or extremely arid part of the country, you are going to have some or much humidity at one or more points during the year.  This is also why you should look to store low moisture foods, preferably under 10%.  It’s interesting that many types of dog food will list the moisture content right on the bag (we have several between 8-12% moisture stored), but people food generally won’t.  This is likely a combination of lack of interest, lack of regulation, and the fact that people foods are almost always listed with a shelf life.  The food types that are available with a low moisture content are those people generally associate with long-term food storage:  grains, beans, legumes, and dehydrated or freeze dried foods.  If you are buying bulk grain from a farmer, they will usually know the moisture content of their products; some bulk packaged foods at the big box stores may also indicate it on their packaging.  A good rule of thumb is grains will shatter and turn to powder if hit with a hard object; other seeds should break in half if bent.  This is another case of using your best judgment.

The second enemy of food storage is oxygen.  Oxygen allows the growth of micro-organisms, some of which can be harmful to food, as well as causing oxidation (especially profound on oils, which become rancid) and spoilage.  Luckily, with the development of oxygen absorbers, it has become fairly easy to eliminate oxygen inside food packaging.  Mylar bags meant for food storage have incredibly low oxygen (and water vapor) pass through.  For example, the larger Mylar bags we carry have an Oxygen Transfer Rate (OTR) of less than 1cc (1/1000th of a liter) per year.  So if you stored a bag of wheat long-term and it was properly sealed with an oxygen absorber, it would take 1000 years to have 1 liter of oxygen pass through the bag.  That’s quite a barrier!

Light is the third enemy of food storage.  This, combined with the others,  is why it is always recommended that you store food in a ‘cool, dark, and dry’ place.  Like oxygen, light causes spoilage and the reduction in vitamin content in food.  However, it is probably the easiest characteristic to guard against.  Mylar itself is an excellent light barrier; a bucket is another.  Storing food in a dark area completes the process.  Even most standard food packaging blocks light sufficiently.  I suggest this is probably the easiest of the 4 enemies to fight.

The final enemy of food storage is temperature.  Depending on where and how you live, it may be easy or extremely difficult to control the temperature at which you keep your food storage foods.  In the old days, many people had root cellars to help preserve food.  Today, if you have a basement, it may stay relatively cool as well.  We are lucky in that we have a split-level ranch where our downstairs/basement stays on average 10 degrees cooler than upstairs.  This allows our food storage to stay in relatively decent condition of around 50-60 degrees year-round.  However, during the height of summer it can get to 70 degrees, depending on how much we use our basement door for outside access.  One rule of thumb is that for every 10 degrees warmer it gets, your foods’ shelf-life is cut in half.  For example, if you go from storing a bucket of wheat at 60 degrees to 70 degrees, instead of lasting 20 years, it will likely only last 10.  You can see how important this makes the environment you are storing your food in.  I’ve seen some great suggestions for storing food in a regular living area to take advantage of the generally cooler environment.  For example, some folks store food in closets or under their beds.  You can find wheeled shelving that will even let you put canned goods under a bed and be able to roll it in and out for access.

As you examine your situation, take some time to plan when you are about to begin a phase of food storage.  Understand the environment you have to work with, and consider buying foods appropriate to that environment.  If you live in area where humidity is high year-round, consider more canned goods than others which will degrade because of that.  If temperature is an issue, be prepared to rotate your foods more frequently.

Quick Friday Updates – Gun Show Edition

I wanted to pass along some quick updates though its a busy, busy day today!

First, we’ve received our first shipment of new bags; I will update Discount Mylar Bags to have them available on Monday.  We did a small run of an awesome 4-layer 5mil 10″x16″ (A little larger than our current 1-gallon bag).  While we love our standard 3.5mil 1-gallon bag, we usually recommend them as an inexpensive way to extend the shelf-life of your food storage by a couple of years.  The 5mil bags are recommended for the ultra-long term storage (10 years+) many folks are looking for.  I already shipped out several pre-orders on these bags, and they are gorgeous!  They are a bit more expensive, but they are more than worth it.

We are also back in stock on our 8.5″x8.75″ Zip Seal Bags.  You can buy them at the old store at Advice and Beans Store today, and I’ll also put these up in the new store on Monday.  I have to say I was surprised by the quantities we sell of this item, as many people use them in their everyday cooking to store pantry items like flour, sugar or baking chocolate ; the Advicewife made me stock these, so I have to give kudos to her!  They are also great if you want to build your own ‘SmartPails’; that is a 5-gallon bucket that contains a number of items that would allow you to make a complete meal from a single bucket.  For example, a SmartPail might contain 1 gallon each of rice, macaroni, and wheatberries, with smaller packs of salt, pepper, garlic, yeast, cream of tartar, baking powder and other items that suit your families tastes.

We’ve also restocked on a full line of AdviceLok Bag Clips.  The largest ones are the perfect size to reseal open oxygen absorbers to keep them fresh.  The smaller ones can be used to seal any number of different types of plastic bags.  They are a patented item, and the best bag clips available on the market.

Tomorrow, we’re excited to be setting up at Bill Goodman’s Gun and Knife Show at the TN State Fairgrounds in Nashville tomorrow.  Everyone is welcome to stop by!  We’ll be offering a great selection of Mylar Bags, Oxygen Absorbers, buckets and other good stuff, but without any shipping costs!  We’re also picking up the sales tax, so what you see is what you get!

Finally, I’ve been working on a longer article about the ‘enemies of long-term food storage’ that should post Tuesday, I hope you’ll come by and read it!

As always, thanks to all our friends and customers; we wouldn’t be here without you!

Article Contest Entry – State of Mind

Good advice from BKB from picturesque Oregon for our Food Storage Article Contest!  And it’s something I don’t cover enough: 

State of Mind

“If I could give just one piece of advice…uh, what were we talking about?…Oh yeah, food storage.”

Most of us never forget to eat or go to work.  We manage to juggle crazy, out-of-control lives with never enough time or money, and still succeed.  Yet somehow the idea of putting a little food and money aside for the inevitable, rarely crosses our minds. Maybe we don’t want to be depressed by thinking about the different scenarios that might threaten to starve us to death. The fact is that we will all face a calamity, whether individually, locally or globally, we will have our own gut check.  Surviving and thriving through the crisis will depend on the preparations we make now.

What’s my advice?  Don’t be ignorant to your situation, threats to your safety, and the remedies that will save you. The first priority is to be aware. What do you have in the cupboard?  If it is an old can of tomato soup and a handful of single serving taco sauce packets, you have a problem.

Pay attention to current events, economic trends and political changes.  As grimy and distasteful as politics and world news may be, it is important to be informed.

In this modern age, we are running full tilt, putting all of our trust in electronics.  Until this system crashes, use it to educate you and your family. 

Listen to your crazy family members, read what the survivalists have to say about what they know.  Use the internet and access the newest developments and products; putting up peaches in glass jars, like grandma once did, may not be helpful. Don’t try to reinvent the wheel. There are smarter, and better prepared, people out there than you and I; use them.  Be educated and develop an opinion. 

Make a plan to do something.  Buy an extra can of spaghetti sauce or build the bomb shelter under the rose beds; doing something as frequently as possible is the key. Coupon clipping has helped hundreds of families collect a year supply of household items in a hurry and stay in budget.  Copy canning, buying extra of what you use everyday, is a painless way to get started.  Another tip: if you skip straight to digging a bomb shelter, you might as well take your last breath and cover yourself in the dirt. 

Preparedness is a state of mind.  It starts with being aware of your surroundings and the world we live in.  Anticipating the problems and preparing to deal with them is as much a mental game as it is a physical one.  Once you condition yourself to visualize the need, you will incorporate being prepared into your life.  Food storage, you ask? No problem.
