Most products we buy in stores include some type of food additive to prevent spoilage, improve flavor or appearance. One of these substances is sulfites.

What we will tell you

What are sulfites?

Sulfites (sulfur dioxides) are sulfur-containing compounds that are actively used in the food industry. These are derivatives of sulfurous acid, including sulfates, sulfites, and metabisulfites. They have antibacterial and antioxidant properties.

Sulfites are preservatives: they prevent food spoilage and help preserve its color. This is because they slow down oxidation processes, allowing food to stay fresher for longer.

Furthermore, thanks to these substances, the growth of microorganisms is inhibited (slowed down), since they prevent the increase in the number of bacteria and the spread of mold.

The permitted amount of this additive in products is 100 mg/kg. The safe daily intake is 0.7 mg per 1 kg of body weight.

What foods contain sulfites?

Sulfites usually appear on food packaging as E220-E228. Foods and drinks that typically contain these additives include:

canned and frozen fruits and vegetables; fruit and vegetable juices; fruit fillings and syrups, jams, jellies and dried vegetables such as apricots, coconuts, raisins and sweet potato cereals; corn flour, corn starch, crackers and muesli; peeled and pre-cut potatoes, including French fries;

tomato pastes; condiments such as horseradish, ketchup, mustard; wines, beer and cider tea; fresh or frozen baked goods, including candy bars and muesli (especially those with dried fruit); ;dressings, sauces, soups and instant noodles.

Fresh fruits and vegetables intended to be consumed raw generally do not contain this dietary supplement.

Health effects of sulfites

“There is nothing wrong with improving food processing techniques to preserve freshness. However, since we do not always know if there is an allergy to them, it is necessary to study the composition of the products more carefully.”

As for the health effects of sulfites, they can actually cause side effects. Thus, in some people these additives can cause allergic reactions, such as bronchospasm and skin rashes.

These substances pose a particular danger to asthma patients, as they can cause asthma attacks. That is why in some countries doctors recommend that patients with bronchial asthma completely avoid foods and drinks containing sulfites.

You should read product labels carefully and consult your doctor if in doubt.

Restrictions on the use of sulfites.

The use of sulfites as a food additive is allowed in all countries. Since sulfur dioxide is an allergen, the manufacturer must include E220 on the label if the content of this additive in the product is greater than 10 mg/kg. If this is not indicated on the label, then its quantity does not exceed the norm.

Sulfites are widely used as essential preservatives for various food products. Despite a long search for less toxic analogues, a substance that has at the same time functional properties like this food additive has not yet been found.
