What Is Sulfur Dioxide and Its Role in Food Preservation
Sulfur dioxide is a preservative found in many foods. It’s commonly used in dried fruits to maintain their color, appearance, and prevent spoilage. As a food additive, it helps prevent the growth of harmful bacteria and fungi during storage. This extends the shelf life of these products, allowing them to remain fresh for longer periods.
Sulfur dioxide works by inhibiting natural enzyme activity that can cause food to rot. It also helps to preserve the natural bright colors of fruits that typically fade after drying. Additionally, it plays a role in preventing browning, which can occur when fruits are exposed to oxygen.
While crucial for preservation, sulfur dioxide needs to be used in moderation. Food manufacturers follow strict guidelines to ensure that the levels of sulfur dioxide in foods are safe for most consumers. The USDA and FDA regulate its use, with clear stipulations for the maximum amounts allowed in different food products.
When identifying foods preserved with sulfur dioxide, you can look for terms like sulfites, potassium bisulfite, or metabisulfites on food labels. This can be helpful for those who are sensitive to it or wish to avoid it. For individuals with asthma or certain allergies, awareness of sulfur dioxide in food is particularly important due to potential health risks.
