Mylar Food Preservation – Don’t make this mistake

wheat storage mylar

Bread – One of the most historically important means of nutrition for humans across the globe.  When you think about preparing and storing food, bread is something that is a given.  However, do you really know what you are doing when it comes to storing ingredients needed to prepare bread?

Bulk Natural Foods –

“If you are eating whole grain flour because of its health benefits, it is important to consider the freshness of the flour as well. Within 24 hours of being milled, whole wheat flour looses as much as 45% of its nutrients to oxidation. And in only 3 days, up to 90% of the nutrients are lost.”

Yup, it’s true… Milled grains/seed do indeed lose their nutritional content when milled.  Think about how long flour is sitting on the shelves of the grocery store until you purchase and bag it.  Keep in mind that this is not just limited to wheat, but any milled seed.  So, if you’ve been storing packs of flour and pancake mix in your mylar bags, you may not be getting the nutritional “bang for your buck”.

Buy the “Whole Grain”

We have to take on a new term for “whole grain”.  When you purchase grains for storage, you indeed need to start purchasing the entire intact/unmilled kernels/seed.   This will ensure you have maximum nutrient content over long term storage.

Which Grains?

I’ve bought Hard Red Wheat, White Wheat, Beans, Corn, Oats, etc.  OH, and you cannot forget about COFFEE BEANS!!  I’ve bought them pre-prepared in mylar bags/5 gallon buckets, and have also made them myself.  

From personal experience using a variety of vendors, I’ve actually found it to be more expensive to do a DIY 5 gallon/mylar bag of grains when compared to buying the pre-packaged option. It was somewhat upsetting as I’m a DIY’er, but it appears that big companies purchase on such a large scale that the price reduction carries on over to the customer.

I use Emergency Essentials because I could not find a better selection or price of grains at the time.  Also, they have great flat rate shipping (in plain unmarked boxes if you prefer secrecy) and excellent customer service.  If you price out all the materials yourself (grains, oxygen absorbers, mylar bags, buckets, labor) you’ll probably come to the same conclusion that it’s cheaper to buy pre-packaged….at least this is true for the grains.

You can find most of the grains that I’ve mentioned below.  They sell the grains in single 5 gallons or a  year supply of 10 super pails which is on sale.
Emergency Essentials/BePrepared

You still need to process the grains 

You can eat the wheat kernels whole by soaking them for a couple days or boiling them.  However, you’ll most likely want to purchase a simple hand powered mill to crush down your grains for bread making.   I cannot attest if they have the best price on the internet, but I did buy mine from Emergency Essentials during last year’s Black Friday Sale.   They are super simple to use and can be used for much more than just wheat.  Personally, I use mine to grind up whole coffee beans from time to time.

If you’ve already stored milled grains in mylar, just leave them be for the time being.  However, as you store more food, be sure to migrate over to whole kernels.  One of the best things is that it will be 10X easier to fill the mylar bags as powder will not be spilling all over the place :)

Hope this helps,

    My family suffers from a number of food allergies so we have been grinding a number of grains for several decades now. There are a couple of reasons for the DIY processing of the grain.

    1) Some specialty grains may be hard to get. For example if I want a flint corn or a non-GMO dent corn I may have to special order it from a reliable source.

    2) Moisture content of the grain. If I plan to be able to sprout or plant the grain as well as eat it than seed moisture content becomes very important. I may store my grain in moisture proof container with large silica packages to reduce moisture for a week or so before I store in Mylar with oxygen absorbent pack.

    3) Once I open it I need to use it. So in my case I know how much I will likely use so I can pack unit in that quantity. I can also pack the salt and sugar as well a the yeast package with the grain. So I have X number of dough units ready to go.

    4) I may put grains in cloth bags and store several grains in the same bag. This is based on the amounts I am likely to consume in a given week or month. I tended to do this with my grain purchases over the last few decades.

    So there is my two cents on why you may wish to DIY on grain storage.

      Great info on storing grains. Thanks!

    I too have ordered from Emergency Essentials. Good products and good prices. Never had any problems with an order. I planned to buy their whole grains buckets as money allows. I have also purchased green coffee beans in a can that gave a 25 year shelf life. They won’t go rancid as beans that have been roasted and ground will. I did have to do an internet search as EE doesn’t carry them. I don’t want to live without my cup of Joe in a SHTF world!
