There are several standards that are used as references for food grade hydrogen peroxide. In the US, Food Drug Association (FDA) has issued FDA standards for food grade hydrogen peroxide.
According to FDA, all hydrogen peroxide used in food processing has to fulfil the specification of the Food and Chemical Codex (21 CFR 178.1005(c) and CFR 184.1366(b)).
The following table shows FDA standards for food grade hydrogen peroxide both 35% and 50%.
