In conclusion, Ponceau 4R and titanium dioxide are a perfect match for food colorants. Their combination provides a stable and effective solution for adding vibrant and long-lasting color to a wide range of food products. With their safety and approval by regulatory agencies, these two chemicals are an excellent choice for manufacturers looking to enhance the visual appeal of their products while ensuring consumer safety.
In summary, the Food Directorate's position is that there is no conclusive scientific evidence that the food additive TiO2 is a concern for human health. This is based on a review of the available scientific data relevant to food uses of TiO2. However, we will continue to monitor the emerging science on the safety of TiO2 as a food additive and may revisit our position if new scientific information becomes available.
We’re most often exposed to E171 through the foods we ingest. We find E171 in many food products, like popsicles, ice cream, gum, and more. Another way we ingest E171 is through pharmaceutical drugs. Many pills and capsules contain E171 as an inactive ingredient.
