Silver
In plain words
The short version
Pure silver in leaf or powder form — a decorative finish on confections and luxury sweets.
Why it's green
It's widely considered safe at the amounts used in food, so we mark it green. The Safety section below has the details.
Safety profile
ADI not specified. Food-grade silver is not absorbed at typical decorative use levels. Chronic high oral exposure (gram-scale, from non-food colloidal-silver supplements) can cause argyria — a permanent blue-gray skin tint — but food-additive levels are many orders of magnitude below this.
