Yes, oxidized chocolate is safe to eat, but it might not taste as good. When chocolate oxidizes, it can develop a whitish or grayish film on the surface. This is called chocolate bloom and happens when the cocoa butter in the chocolate rises to the surface. It occurs due to temperature changes or improper storage. Although the appearance changes, the chocolate remains edible. However, the taste and texture might be affected. It could taste a bit stale or have a rougher texture. I’ve consumed slightly oxidized chocolate before; it’s safe, but the flavor might not be as delightful as fresh chocolate.
