Food additives are substances added to food to maintain or improve its safety, freshness, taste, texture, or appearance. They can be natural or synthetic and serve numerous functions. For instance, preservatives such as sodium benzoate extend the shelf life of products by inhibiting the growth of bacteria, mold, and yeast. Emulsifiers, like lecithin, help to maintain a uniform mixture of ingredients that would otherwise separate, such as oil and water in salad dressings.

1. Stabilization One of the primary functions of E472 is to stabilize emulsions, which are mixtures of oil and water that normally would separate. By reducing the surface tension between these two phases, E472 allows for a more uniform distribution of ingredients.

Another significant benefit is its broad-spectrum antifungal activity. Pimaricin is effective against a wide range of fungi, making it versatile across various applications. It can be particularly effective in combating fungi that are resistant to other preservatives, thus providing an additional layer of protection against spoilage and degradation.

As food scientists continue to explore natural alternatives and more efficient preservation methods, the role of traditional preservatives may evolve. However, for the foreseeable future, E211 and E202 will remain key players in the landscape of food preservation, employed with caution and regulated standards to safeguard public health. Ultimately, achieving a balance between food safety, quality, and consumer preferences will continue to drive innovations in the food preservation industry.

As a result of these findings, several countries and regions have moved to ban or restrict the use of titanium dioxide in food products. France, for example, was among the first to announce a ban on E171 in food starting from 2020, citing the potential health risks associated with its ingestion. Other jurisdictions, including some parts of Europe, are contemplating similar measures.
