Tate & Lyle Fairtrade Icing Sugar contains two main ingredients: 97% cane sugar and 3% maize starch. It is important to note that the product is a blend of cane sugar and maize starch. While the product itself does not contain common allergens like gluten, milk, eggs, or nuts, some suppliers or packaging facilities may handle other allergens. Some retailer websites indicate that the product may be unsuitable for those with Sulphur Dioxide or Sulphites sensitivities. The 3kg bag is marketed as suitable for vegans and vegetarians. However, individuals with severe allergies should always check the product packaging for the most accurate and up-to-date allergen information, as cross-contamination can occur during manufacturing and packaging.
