Question

ph value of tomatao sos​

Answer 1

Explanation:

Tomato sauce should be OK around 4.3 IF it's goes into the jar HOT...205°F+. Cap it, invert for 5 minutes and let it cool. If you can't reliably hit your fill temp, I'd aim for lower or process in a water bath. You're looking at 0.35-0.45% (w/v) citric acid in a jar of tomato sauce at that pH range.
