Does Coffee Have Sulfite in It? Here’s The Answer!

by sundhedsvagten

Coffee gets produced in large quantities to fulfill the great demand. And most food items that are being produced in large quantities contain sulfite for preservation and packaging purposes.

A common question that pops up in our mind is whether coffee contains sulfite or not?

Generally, coffee does not contain any sulfite, but a few coffees may contain sulfite due to the roasting or packaging.

These coffees don’t contain sulfite naturally.

A few coffees contain sulfur as a result of taste development. For example, the amino acid cysteine and the methionine in the coffee contain sulfur.

The sulfur in the coffee turns into sulfite if given the right conditions.

Is Sulfite Dangerous to Consume?

Sulfite is usually harmless and poses no threatHowever, sulfite can be dangerous to people sensitive to sulfite or have sulfite allergies.

The allergies to sulfite among people can be of varying degrees. These allergies depend on the sensitivity people have towards sulfite.

It is important to note that sulfite allergies can become life-threatening if you have asthma and sulfite sensitivity. This can lead to severe reactions and become life-threatening if not treated correctly.

The symptoms or reactions from sulfite allergies include the following:

  • Dizziness
  • Trouble swallowing
  • Difficulty breathing
  • Upset stomach
  • Vomiting
  • Diarrhea 
  • Drop-in blood pressure
  • Hives and itchiness
  • Flushing

Is Coffee High in sulfite?

Most coffees are sulfite-free; however, some coffees do contain sulfite.

The green beans of coffee in raw form do not contain sulfites. This is because sulfite is naturally present in most plant-based items, and since coffee is also plant-based, the coffee proteins contain sulfur.

The green beans do not contain sulfite, but the roasted coffee beans contain sulfur. This sulfur turns into sulfite when exposed to oxygen in roasting coffee beans.

Therefore, the roasting process is essential as it inevitably contains sulfite. But the degree and strength of sulfite can vary depending on the roasting temperature, time, type of coffee beans being used, and the type of roasting.

To have a sulfite-free coffee, make sure the roasting process is slow-roasted coffee beans that are not roasted at high temperatures.

Coffees that contain sulfite

●    Instant coffee

Instant coffee does contain sulfite but is only limited to a certain degree.

Sulfite-free coffees do exist. However, the manufacturers don’t have a sulfite-free label on the coffees, but you can check for the ingredients. 

The sulfite content is mostly less than 0.001%, but if higher, they will mention it on the label.

●    Decaf coffee beans

When you decaffeinate the coffee beans, the chemical compounds in the coffee are reduced automatically. This also minimizes any sulfite in the coffee, making it to 0. You can find decaf coffee beans easily in any local grocery store or roasters.
