Sulfur dioxide and sulfites are compounds that can occur naturally and are commonly used for their preservative effects. They are allowed to be present in various foods, including dried fruits, breakfast sausages, and hamburger meat. They are used to extend the shelf life of products as well as to kill bacteria and are popular because they preserve the color of products and have a softening effect. Sulfur residues in foods are considered to be of low toxicity. However, it may cause allergic reactions in susceptible individuals, such as asthma attacks, headaches, and nausea. Therefore, for prepackaged foods with levels exceeding 10 mg/kg or 10 mg/L (expressed as SO2), the full name of the food or beverage in which it is present must be indicated on the label. People sensitive to SO2 should read food labels carefully each time they purchase a food product, looking for the name of the SO2, sulfite, and sulfite derivatives or their International Numbering System numbers (220, 221, 222, 223, 224, 225, 226, 227 and 228), and avoid all foods containing these compounds.
Unlike most allergens, no protein or DNA can be extracted from sulfites. Our highly skilled scientists develop highly sensitive chemical methods to determine their presence in food. Our advanced technology platform will provide efficient, cost-effective sulfur dioxide and sulfite testing services to ensure your 100% satisfaction.
