Sun dried tomatoes canned at home isn't recommended,for the most part in my opinion,people who dehydrate their own tomatoes don't always do it properly.We already know some dehydrators aren't the best for this purpose.
Some tomatoes like Roma's are best for it,but people at home might have a different take on it.
What you buy in stores has most likely been chemically treated by sulfuring.By doing that the processors are guaranteed the tomatoes will keep their color,and flavor.Not all are treated in that process.But for those that dry tomatoes outdoors it's necessary to do.And they have to keep germy little things away from the product at all times.
For us at home,it's always best to dehydrate them fully.Store airtight.Use them as needed.You could always infuse them in olive oil and herbs,the night before.Store in the fridge no more then a few days,just to be safe.
