Canned tomatoes and headspace

redstar57
9 years ago

Although filled for 1/2 inch headspace, a number of the quarts of tomatoes I've canned over the past few days have one inch headspace when cooled.

I was careful to release any trapped air before processing.

Tomatoes had been cooked down to sauce consistency and were hot at time of filling.

Two questions:

1) Any idea why this is happening?

2) What is the best way of handling these quarts? Can I re-process them? Should I just dispose of them? Or can I keep them as-is but assume reduced shelf life? If so, what would be a safe estimate of that reduced shelf-life?

Thanks in advance for your help,

Mike (NJ)
