21 CFR Part 172 - Food Additives Permitted for Direct Addition to Food for Human Consumption

What it says

Part 172 lists food additives that FDA has approved for direct addition to food, such as preservatives, colors, flavoring agents, sweeteners and emulsifiers, together with the specifications and conditions under which each may be used. An additive must be used only in the foods, at the levels and for the purposes the regulation allows.

Paraphrased for plain-language clarity. Always verify against the current published regulation text.

What it means in practice

• Each listing has its own limitations, so permission for one use does not extend to others.
• Specifications for purity apply to the additive as supplied.
• Some additives require labeling statements or declarations.

What FDA inspectors look for

• Whether additives used are listed for the intended use.
• Whether levels stay within limits.
• Whether labeling of additives is correct.
