Tomatoes processing times

It seems that on many sites that the processing times for whole or half tomatoes in a pressure canner is 25 minutes, but while looking on National Center for Home Food Preservation web site the process times in a Pressure canner is reduced.

You are correct. The site you have linked to is a reliable resource and I often use it myself. The times I have quoted on my canning tomatoes page I drew from my Ball Blue book.

My directions on Simply Canning are for canning tomatoes raw with no added liquid. They are just in their own juice. If you look at this page canning tomatoes with no liquid added. on that same web site the times are the same.

The page you saw with the different processing times uses a different packing method than I do. Thus the times are different.

The site you mentioned has listed different packing methods for canning tomatoes. And options for using different weights at more or less times. I have listed only one.

It is surprising that different methods will require different time and pressures.

Thank you for pointing this out. I am always happy to be "checked up on". I want to give as accurate information as possible. Also there may be someone who prefers a different packing method than I do and will want to use the times offered there.

I always recommend calling your local extension service for more help if there are any concerns.
