According to German food law, food or food additives are defined as substances that are added to food for technological reasons. They are added to improve the appearance of the food (colour, structure), to enhance or change its taste or smell or to extend its chemical or microbiological shelf life (preservative).
Food additives can be either synthetic or natural substances. Thus, food additives are able to change or stabilise the utility and nutritional value of food and ensure its undisturbed production.
The list contains the food additives that are currently allowed to be used throughout the EU (as of November 2011) under a registration number (E-number) to be specified.
