Functional ingredients or additives ensure that our foods have a longer shelf life, look more attractive, taste better and ensure a good binding. In short, they improve the properties of foods. The additives are in almost all of your daily foods, especially packaged foods. For example, they ensure that your meat products do not turn brown and that the yogurt or quark in your fridge does not turn into watery substance. Because let's face it, that doesn't look tasty, does it? Even in organic food production, additives are used to a limited extent.
