Caustic Sulfite Caramel
In plain words
The short version
Class II caramel — sulfite-processed sugar coloring used in cognac, sherry, and soy sauce.
Why we flag it amber
It's permitted and generally considered safe, but there are a few reasons to be mindful — like sensitivities in some people, debated studies, or intake limits. The Safety section below explains the specifics.
Safety profile
ADI of 0–160 mg/kg body weight. Does not contain 4-MEI (the 4-methylimidazole concern is specific to ammonia-process caramels III and IV). Residual sulfite is generally low but products may need to declare sulfites depending on jurisdiction.
