E210 is a food additive approved by the European Union (EU) and used as an antifungal and antibacterial natural preservative (in an acid medium) in food products.
E210 is also known by the common name of benzoic acid, but may also be referred to as carboxybenzene or dracyclic acid.
This chemical is produced by hydrolysis of benzonitrile and benzamide and can be purified by the recrystallisation from water, due to its high solubility. E210 also occurs naturally in edible fruits and vegetables.
Examples of food/drink products that may include E210:
- marinated herring
- marinated mackerel
- soft drinks
- dessert sauces
- salad cream
- salad dressings
