E227 is a food additive approved by the European Union (EU) and used as an antimicrobial synthetic preservative in food products. It can also be used as a firming agent and disinfectant.
The common name of E227 is calcium hydrogen sulphite.
E227 is a calcium salt of sulphurous acid. It works as a firming agent due to the presence of calcium (especially in canned vegetables). The liver reduces E227 to a sulphate that can be excreted as a component of urine. As with other sulphurous acid salts, E227 destroys the vitamin B1 content of the food, which is important for a healthy heart and nerves, as well as producing energy for the body.
E227 has been known to induce asthma attacks and has been banned in Australia.
Examples of food/drink products that may include E227:
- canned fruit
- canned vegetables
- fruit juice
- fruit jellies
