Some small amount of bubbling is common as the remainder of the air trapped in the solid fruit pieces escapes into the liquid. But with jars that are "mostly liquid" to begin with I have never seen any actual foaming. I'd be concerned too and personally, I'd be inclined to do them over from scratch.

But assuming they were processed for the correct amount of time and given that you added the lemon juice and all the jars sealed, in theory they should be safe to consume.

Could you possibly post a photo?

It almost looks like there was some dish soap inside the jars? Possible? I'd open one and see what the bubbles smell like or even what the tomatoes taste like since it has only been 24 hours. Soapy taste??

But yeah I wouldn't trust those either since they are re-foaming up. I tend to bend over backwards safety-wise so personally I'd be inclined to toss them but that's just me.

Mine has done the same..Has anyone found out what causes this..are they safe to eat..

I think it is caused by the blending of the tomatoes. But there is a solution: stir. Use a rubber spatula to finish faster not the plastic bubble freer. And be ready to clean the neck of your jars! Lol!

I am noticing that addind more liquid to the blender is helping keeping some foamming out! Hopefully this
