"E Numbers" are codes used to identify food additives in the European Union. These additives can serve various purposes, such as preserving freshness, enhancing flavor, or improving appearance. Each E Number corresponds to a specific substance, making it easier for consumers to understand what is in their food. Many E Numbers are derived from natural sources, like fruits or vegetables, while others are synthetic. The use of E Numbers helps ensure that food products meet safety standards and regulations. However, some people may choose to avoid certain additives due to allergies or personal preferences.
