If by processing you mean putting them thru the canning process then yes. As far as self life anything properly canned will be safe as long as the seal remains intact. There is several cases of canned goods from the civil war era still being safe to eat, the problem is it will not taste that good as the longer the canned food sits the softer the texture becomes. So I would say you should try and eat it within 2-5 years. but as long as the seal is intact and the taste is fine it should be ok.
