The Truth About Sulfur Dioxide And Your Food

The Truth About Sulfur Dioxide And Your Food

When you think of ingredients like mango, papaya, and pineapple, tasty fruit with tropical flavors likely come to mind. However, what if, while you were eating these fruits, you knew you were also eating harmful preservatives? It’s an unpleasant truth, but one that is far too common amongst dried fruits on the market today. With the start of the new year, we thought the timing was appropriate to dive into the topic of Sulfur Dioxide (SO2) and how it impacts the ingredients you are purchasing.

What is Sulfur Dioxide?

If you are unaware exactly what Sulfur Dioxide is, it is a nonflammable, colorless gas with an aggressive odor. Primarily, sulfur dioxide is released from the combustion of fossil fuels. Most commonly, it can be inhaled from air pollution.

This chemical compound was first used in foods beginning in the 1970s. But, it was banned in fresh fruits and vegetables by the Food and Drug Administration in 1986, as they were causing numerous health issues for consumers who had asthma.

Sulfites In Food

A more common way of describing this chemical compound concerning food is with the term sulfites. Sulfites release gas, which helps keep the food free of bacteria and preserve the taste and color. Today, sulfur dioxide is used in many foods such as meats, baked goods, and dried fruit.

Take a look at a package of dried fruit you may have at home. Turn it over to review the ingredients list. If sulfur dioxide or sulfites are listed, there may also be in parenthesis the words “for freshness.” While this isn’t inherently incorrect, it leads the consumer to believe the preservative is safe to eat.

What consumers don’t know is how damaging the effects of SO2 can be on the consumers’ health. The good news is the U.S. Food and Drug Administration requires foods containing more than ten parts per million of sulfites be on the food label.

However, what is even more concerning, are the brands that consumers are purchasing that do not list the use of SO2 on their labels because they fall under this threshold. It is possible for manufacturers, during the production process, to utilize sulfur dioxide. The most common way this is done is to soak the fruit in SO2 and boil it long enough to meet the FDA requirement of fewer than ten parts per million.

Not only is this secretive use of sulfur dioxide alarming, but it changes the texture of the dried fruit completely, making it feel almost erasure-like in the consumer’s mouth. While texture might not be everything, taste and nutritional values are certainly impacted in this process, which ultimately matters to your customer.

Are Sulfites Harmful?

The Food and Drug Administration lists sulfites as,” generally recognized as safe.” However, sulfites can have differing effects on everyone. Part of the population suffers from a sulfite sensitivity, which can manifest with conditions similar to asthma, such as wheezing or labored breathing.

235 million people in the world suffer from asthma. If your customers also do, then they are at a higher risk for a sulfur dioxide reaction.

Sulfites In Pet Food

If you are looking to develop a pet food or pet treat, we also wanted to share that high-quality ingredients make a big difference.

Research shows that cats and dogs who consume foods with sulfites can ultimately lead to suffering from thiamine deficiency. Animals with this deficiency can suffer from depression, dilated pupils, and ataxia that may lead to seizures and sudden death. The last thing your company wants to experience is a complaint or lawsuit from a consumer on behalf of their pet.
