Direct additives are substances that are added to foods with a specific intent, such as extending shelf life, improving flavor, enhancing texture, or increasing nutritional value. They are distinguished from indirect additives, which may migrate from packaging or be introduced in trace amounts during processing.

Regulatory oversight varies by jurisdiction but commonly requires safety assessment and authorization before marketing. In the United States, the Food and Drug Administration regulates direct food additives; substances must be approved for each intended use and listed in the Code of Federal Regulations. Substances that are generally recognized as safe (GRAS) may be used without formal approval under certain conditions, though GRAS determinations can be re-evaluated. In the European Union, direct additives are authorized and listed in the European Union list and may carry E-numbers; member states enforce labeling and usage limits. Codex Alimentarius provides international guidelines to harmonize safety standards.

Common classes of direct additives include preservatives (sodium benzoate, sorbates), antioxidants (ascorbic acid), colorants (tartrazine, beetroot color), flavor enhancers or flavorings, sweeteners, emulsifiers, stabilizers, and processing aids. The exact permitted substances and limits depend on jurisdiction and product category.

Labeling typically requires listing direct additives in ingredients with their common name and sometimes a code or E-number. Many jurisdictions require disclosure of all intentional additives, with specific dosing limits and usage conditions.

Safety assessment relies on toxicology data, consumption patterns, and cumulative exposure. While many direct additives are considered safe under approved conditions, ongoing monitoring and periodic re-evaluation exist to address new science and consumer concerns.
