E250 is a food additive
approved by the European Union (EU) and used as an antibacterial synthetic
in food products, as well as a colour fixative. It is specifically effective
at inhibiting the bolulism-causing bacteria, Clostridium botulinum.
The common name for E250 is sodium nitrite.
E250 is the sodium salt of nitrous acid. It
can be oxidised in air to form sodium nitrate – a useful reducing
E250 (sodium nitrite) has been know
to cause hyperactivity and is restricted in many countries. Once in the
stomach, nitrates can form nitrosamines,
which are thought to be carcinogens.
Recent research has indicated that E250 may
cause dilation of blood vessels, hence it may therefore have positive
applications in the treatment of heart attacks, pulmonary
and sickle cell anaemia.
Examples of food/drink products that may include E250:
Meat (smoked, cured and processed), root vegetables and fish.
