Unlike many of these E-numbers and various food additives, this one doesn’t really have any concerns. It’s completely vegan. Well, at least regarding its vegan-status. We’ll go over its safety below.
Wait, So What is E224 Made Of?
E224 (Potassium Metabisulfite) is made of Sulfurous Acid, or rather an isolated portion of Sulfurous Acid called Potassium-sodium.
So in plain English: Other Chemical compounds! Beyond that there’s nothing more I can say without being technical/scientific. But there’s nothing really to worry about, which leads me into the next question:
Is E224 (Potassium Metabisulfite) Safe?
While harmful and dangerous in its concentrated form, there’s no evidence it’s harmful when used in the microscopic amounts used to preserve fruits/vegetables or alcohol (beer/wine), which are the only potentially vegan foods it’s likely to be in.
