Interesting stuff Jeekins!
The labels are especially interesting to me. The US grown tomatoes having calcium chloride and Citric Acid.... weird.
Calcium Chloride would be a "salt" (no, not salt, a "salt" or chalk) which I would expect to be more of a basic additive.... Maybe that's why the citric acid, to bring it back to balance?
YT!! We need a chemical analysis over here!!
