Specifically I'd like to know what a certain line on a foreign (USA) product means. It says something about the product's additives and I'd like to know what it means and what is actually in the product.
Where should I ask this question?
Certainly not on-topic at Lifehacks as there is no hackery involved to solve a problem.
Your best bet is probably Seasoned Advice, which covers cooking.
Check their tour first to make sure that what you wish to ask is on-topic there.
