Description
E1205, known as Basic methacrylate copolymer, is a food additive belonging to the 'Others' category according to European classification. It is a synthetic polymer derived from methacrylic acid and its esters, mainly dimethylaminoethyl methacrylate and methyl methacrylate. Industrially, it is obtained by emulsion or solution polymerization, controlling molecular weight and composition to achieve desired properties. It is a white or slightly yellowish powder, soluble in water and polar organic solvents, with a basic pH in solution due to tertiary amino groups.
Its main function is to act as a coating agent in the food industry, forming films that protect food from moisture, oxygen, and other environmental factors, as well as improving the controlled release of flavors or nutrients. It is also used as a glazing agent and to prevent clumping.
Historically, it was approved in the European Union after evaluation by the European Food Safety Authority (EFSA), which considered it safe for use in certain applications. EFSA established an Acceptable Daily Intake (ADI) 'not specified', meaning it is not considered a health risk at the levels used. The World Health Organization (WHO) has also evaluated its safety, concluding that there is no evidence of significant toxicity.
Regarding labeling, it must appear in the ingredient list as 'Basic methacrylate copolymer' or with its number E1205. It is important to note that although it is considered safe, some consumers may prefer to avoid it because it is a synthetic additive.
In summary, E1205 is a functional and safe food additive, widely used in the industry to improve the quality and preservation of foods.
E1205 is mainly used as a coating agent in food products, especially those requiring protection against moisture or controlled release of ingredients. According to Regulation EC 1333/2008, it is authorized in the European Union for use in food supplements, confectionery products (such as chewing gum and candies), and certain processed meat and fish products. Maximum limits vary by category, but are typically up to 1000 mg/kg in food supplements and 500 mg/kg in confectionery.
In the Spanish market, it is found in sugar-free chewing gum, hard and soft candies, and some vitamin supplements. Compared to the FDA, in the United States this additive is not approved for direct food use, although it is allowed in packaging materials. In Japan, its use is restricted to certain products.
The main function of E1205 is to form a protective film that prevents moisture loss and improves texture, as well as allowing gradual release of flavors or nutrients.
Studies conducted by EFSA and WHO have not documented significant adverse effects associated with the consumption of E1205 at authorized levels. Its acute, subchronic, and chronic toxicity, as well as its genotoxic and carcinogenic potential, have been evaluated without finding evidence of risk.
The biological mechanism is based on the fact that the copolymer is not absorbed in the gastrointestinal tract due to its high molecular weight, being excreted unchanged in feces. No specific sensitive populations have been identified, although people with allergies to acrylates could present reactions, but this is extremely rare in foods. No interactions with medications are known. EFSA concluded that E1205 is safe for the general population, establishing an ADI 'not specified'.
In conclusion, there are no documented side effects in humans under normal conditions of use.
