Carbon Dioxide
In plain words
The short version
The bubbles of every carbonated beverage — also used in modified-atmosphere packaging.
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
Considered safe at all food use levels. CO2 dissolved in water gives carbonic acid (mildly acidic) — contributes to the slightly acidic pH of carbonated beverages. Excessive intake can cause bloating; no chronic safety concerns at typical exposure.
