Dont know about fruit leathers. Yes, vaccum packed food, will last considerably longer than none vaccum packed food. It all differs though.
If I had packed up some food, [and of course I'd never admit to that ...
]
It would have been kidney beans and rice with oxygen absorbers, vaccum packed in mylar, stored in a cool even temperature, basement is ideal, inside food grade plastic 5 gallon containers, and tins of spam. That should still all be good in 20 years.
I think the people who have at least a years supply of food, stashed, and then rotate it, are doing the right thing.
So you've always got a years supply to fall back on. Thats probably more than 99% of the population have.
Thats not a crazy doomsday prepper thing. Its just good sense IMO.
A very good book is How to live on Wheat by John Hill.
I dont have any winter wheat, stored, but its something I'll be getting in future. I also got a really good little hand grain mill.
The short term stuff for camping, I like my proper comfort food, and so I have mince beef recipes, and baked bean leathers, tomato powder in small nalgene bottles, dried potato, mr mash, stuff like that. They all go in plastic bags.
The plastic bags vary widely in price. The foodsavers own make are expensive for instance. They have to be embossed to vaccum properly. But there are other branded bags, on amazon, which are very similiar and work just as well. You can boil in the bag with these. But the plastic bags let in oxygen at a much faster rate than mylar.
Foodsaver vaccum sealers will not seal smooth plastic bags, or mylar. I had one but sold it.
I now have a kf108 vaccum sealer, which I ordered from the states. It can handle mylar, below 7mm thick. Smooth plastic. Anything really.
Im sure someone else will be along with some advice?
I kinda delve into the whole prep subject in bits, now and again.
