We went to a seminar that included food storage tips and a vendor was telling people that they could can all kinds of nuts by dry canning. Just place them in a jar and seal - place in the oven at 250 degrees for 2 hours were the approximate directions.
We were very interested in this, however we have never been able to find confirm this. Most nuts have oils that I believe would go rancid even if they were dry canned or vacuum sealed. Peanut butter (non-MRE types that may or may not really be peanut butter) can’t be stored long term for this reason.
Am I wrong on this or do you or anyone else have any knowledge of this? It seems like dried/preserved nuts would be terrific food to keep on hand if they would last more than a few years. We have done a bit of googling without success.
Thanks in advance!
from the linked site:
Not all foods, however, are right for dry pack canning. Only items that contain less than 10% moisture can be dry pack canned. Good candidates for dry pack are:
Beans
Flour
Pasta
Oats
Rice
Sugar
Wheat
Powdered milk (non-fat)
Check carefully which products are safe for dry pack canning. Foods with higher moisture or oil content, such as nuts, cereal, brown rice, or whole wheat, are not recommended.
Other foods like brown sugar, baking powder, and oil should also not be dry packed. They should be kept in their original containers and rotated often.
you post, re dry canning - “Just place them in a jar and seal - place in the oven at 250 degrees for 2 hours were the approximate directions...”
This may be very dangerous - exploding.
n dry canning - the instructions I have seen over and over - say put the jars in oven WITHOUT lids - at 200 for 1 hour -
Here’s an article that explains it - it’s the same as I’ve seen in magazines

“Most nuts have oils that I believe would go rancid even if they were dry canned or vacuum sealed”
‘Rancidity’ occurs when the unsaturated oils in the nuts, etc are oxidized by oxygen in the environment. If it were dry canned or vacuum sealed so as not to have any oxygen in the container, rancidity should not occur.
