- In the context of "inorganic chemistry|mainly|UK": alternative spelling of sulfite
Commercial use in wineSulfites occur naturally in almost all wines. They are also added to wine as preservatives to prevent spoilage and oxidation.
In the US, wine bottled after mid-1987 must have a label stating that they contain sulfites if they contain more than 10 parts per million.
In the EU an equivalent regulation came into force in November 2005. Organic wines are not necessarily sulfite-free.
Some humans are allergic to sulfites. It is an undeclared allergen that may cause breathing difficulty within minutes after eating a food containing sulfites. Asthmatics and people with allergies to aspirin (also known as salicylate sensitivity) are at an elevated risk for reaction to sulfites. The reaction can be fatal and requires immediate treatment at an emergency room, and can include sneezing, swelling of the throat, and hives. Those who are allergic to sulfites are urged to avoid products that could contain them.
