The Additives Used in Bakeries

Humans are frequently exposed to toxicants through food. A large number of naturally occurring contaminants are found in foods. When it is processed and prepared, substances are introduced which create chemical changes and introduce compounds not normally found in raw agricultural products. Furthermore, chemicals are added to achieve specific technical effects. Often, additional substances are introduced in very small amounts, and the majority are byproducts of agriculture and packaging. Additives are not considered “nutritional” even if they possess nutritive value.[1]

They are substances added to food to modify or impart flavor, enhance taste, appearance, or stability.

Over time, many different food additives have been developed both from natural and artificial sources in order to meet the needs of the food industry. Additives are needed to ensure processed food remains safe and in good condition.[2]

The Difference Between Natural and Artificial

The main difference between natural and artificial additives is the origin of the chemicals. The natural additives must come from natural sources, such as plants or animals. Artificial additives are formulated in laboratories. It is possible that the actual chemicals in these two kinds of additives may be identical. However, the chemical structures of the individual molecules may be indistinguishable.[3]

The "E" Number

The European Union uses an “E number” to identify all approved additives to regulate them and inform consumers. The Codex Alimentarius Commission has adopted and extended this numbering scheme in order to identify all additives internationally, regardless of whether they have been approved for use.

Despite the fact that all E numbers are prefixed by “E”, countries outside Europe use only the number, regardless of whether they have been approved in Europe.[4]

The U.S. Food and Drug Administration (FDA) has listed these products as “generally recognized as safe” (GRAS).
