Sun Creams With Titanium Dioxide-How Is Titanium Dioxide Used In Food
Titanium dioxide (TiO2) is used in food primarily as a coloring agent. It is recognized by the Food and Drug Administration (FDA) as a food additive and is designated as E171 in the European Union. Here are some ways in which titanium dioxide is utilized in food:
1. **Whitening Agent**: Titanium dioxide is used to make food products appear whiter or brighter. It is often added to products where a white color is desired or expected by consumers, such as candies, chewing gum, baked goods, and dairy products.
2. **Opacifier**: In addition to whitening, titanium dioxide can also provide opacity to products, making them look less transparent. This is useful in beverages, sauces, and condiments where a cloudy or opaque appearance is preferred.
3. **Colorant in Coatings**: It is used in the coatings of tablets and candies to give them a smooth, white appearance and to provide a base for other colors that may be applied on top.
4. **Food Additive in Confectioneries**: Titanium dioxide is often found in confectioneries to enhance the visual appeal of the product. It can be used in frostings, icings, and cake decorations to achieve a pure white color.
5. **Dairy Products**: In products like cheese, yogurt, and cottage cheese, titanium dioxide can be used to achieve a consistent color and to offset any natural discoloration that may occur during processing.
6. **Processed Foods**: It is also used in processed foods like breakfast cereals, salad dressings, and frostings to maintain a desirable appearance.
While titanium dioxide is generally recognized as safe for consumption, there has been some debate and research into its potential health effects, especially when it is used in its nanoscale form. Some studies suggest that nano-sized titanium dioxide particles could have different biological properties and may pose different risks compared to larger particles. As a result, there is ongoing research and discussion regarding the use of nano-sized titanium dioxide in food products.
Regulatory agencies such as the FDA and the European Food Safety Authority (EFSA) continue to assess the safety of titanium dioxide as a food additive, and its use is subject to specific regulations and maximum allowable levels in different types of food.
