Shelf life of home canned goods

Hey guys, looking at buying my first pressure canner, and learning how to can. My question is, what is the average shelf life of properly canned food? I will most likely be doing fresh veggies, various stews, and fruit/jam.. Any thoughts would be greatly appreciated.

To be honest, I am torn between a dehydrator or a pressure canner.. I am new to both. I have read dehydrated foods have a long shelf life. I have tried to search but can't seem to come up with a solid answer for home canned goods.

It's really hard to find an accurate answer on this. About the best I've been able to find is that home-canned foods will retain their nutrition for 2-5 years, depending on storage. Some say they will slowly start to lose their nutritional value after that...but...if the lid is still sealed, the product is still safe to eat regardless of how old it is.

I've been canning and dehydrating for a couple of years now. Between the two methods, if I could only choose one, I prefer canning and would purchase a Pressure Canner over a Dehydrator any day. With the exception of the potatoes I've dehydrated (both white and sweet in my Excalibur) I'm not overly impressed with the dehydrated fruits/veggies but love everything I have canned. The dehydrator does have it's place but if I had to do it over and could only purchase one, it would be the canner.

HTH.

Ditto canner.
I agree with the above - but add that storing your foods in teh dark will be necessary for long life. Daylight destroys the nutrients in canned goods faster than anything and will in fact bleach food.

A lot of dehydrators are just small fan ovens. Do you have access to a fan oven where you live that can run at a low temperature?

I think you will get more joy out of canning for now, and will be able to add the dehydrator in down the track. :)

Properly canned foods will last literally for decades as long as the seal is intact. Doesn't metter whether it's home canned or store bought. The food inside is sterile, so there's no bacteria to grow in it, unless it can somehow get in from the outside.

Over time the food will lose flavor, texture, and some of the nutrition, but it never actually spoils as long as it remains properly sealed.

Re-canning

I want to share something I learned to do with others. I have canned for years now.....but I tried something new and it worked so well. I lost all interest in canning pickles, so I bought a huge jar of pickles for under five dollars. I took it home and poured them into a big pan and 're-heated' them to the boiling point and then stayed there for ten minutes. I heated my jars in my oven on 200 degrees for twenty minutes then filled my 'smaller' jars with pickles and then sealed them. now I had eight smaller jars out of one huge store bought big jar and all for under five dollars. no need to cold pack them at all the jars sealed tight. one small jar of pickles in the store cost four dollars! I then tried this same process with all kinds of size 10 large canned foods I bought at the store. vegetables, tomatoes, tuna, ect...... size ten cans will give you six to eight 'smaller' portions for family's with only two or three people. makes your money go a lot further! fills your pantry faster. great for olives and syrups and items you really don't buy too often. re-canning!! who knew!!:)
