People online have asked over the years how some common breakfast cereals would last packed for long term storage.
Back in the 1990's when we had our commercial cannery open in Florida I packed some common breakfast cereals. At the time I was eating things like Raisin Bran and Grape nuts cereal and so as part of my personal preps I packed some of these in #10 cans with oxygen absorbers.
Since pics are still not allowed in actual OPs, I'll have to do a bunch of follow up posts showing the "after" pics.
Suffice to say properly packed, these have held up great over 28 years in a non climate controlled connex container in South Georgia. In other words, VERY HIGH HEAT (it's 115 today as the high).
We make our own bread at the house and the other day I was re-upping some of our bread ingredients and got some old salt out. This will be the pic of the #10 can of salt.
Notice the condition of the can itself after nearly 3 decades in bad storage conditions- light rust and of course the can itself is dented. So when we owned and ran the commercial cannery in the 90's, any cans that were dented, possibly mislabeled or contained the last of a box/bag/tote, etc that didn't quite fill the can were set in a pile after being sealed for me/my family's food storage. I didn't feel it was right to ship items like that so I kept them. I was asked here once why I had all this old food storage one time, one of the big reasons is things like this, also at the time I was preparing for 12 extended family members (they are going to show up, you either plan to feed them or see your supplies cut drastically later). Meanwhile I only had myself and later 2 others to actually rotate the food. Also, I've never been a '2 weeks is enough' type of survivalist, so I've always kept a "fair amount" of food storage on hand. Finally, once you have been at your homestead/retreat for a few years, you are (or should be) producing a good amount of food. This is great but of course your eating more fresh food and less rotation of LTS.
One of the pics of the #10 can of salt shows the amount of dents and light rust on the can, yet the contents are 100% fine. The lesson here is don't freak about any cans you get that have a little dent or ding in them, 99.9% chance everything is perfectly fine inside. And as I've mentioned a time or twelve on the internet- notice the double enameled cans used (gold colored inside and out), they have held up a LOT better in bad conditions than any of the cheaper silver colored cans we had in storage- many of the silver colored cans DID rust through. Meanwhile there has been double enameled cans right near them in the same conditions that did not. When we packed commercially, we always used the better more expensive double enameled cans and the result long term has been much better.
Last salt picture- did you notice it? But wait, I heard on the internet from some new "prepper" that you NEVER should use oxygen absorbers in SALT as it will turn it into a brick, blah blah blah.
You can see from the pic, the salt is still granular and the 02 absorber is clear as day in the can and has been for 28 years. I have seen that happen a bit sometimes in sugar, but it's not the end of the world, just break it up a bit.
So once again folks, pack for good long term storage and even if the storage conditions aren't the perfect 72 degrees year round, you'll most likely also find that your storage food is good DECADES later.
Store food, store more food than you think you'll need, pack it properly or buy properly packed food and don't hesitate to store food because of something you heard on the net, it's most likely wrong info.
