E171, also known as titanium dioxide, is a white pigment commonly used in food, cosmetics, and pharmaceuticals. It helps enhance the appearance of products by providing brightness and opacity. E171 is often found in items like candies, sauces, and baked goods, where it improves visual appeal. In recent years, the safety of E171 has been debated, particularly regarding its potential health effects when consumed. Some studies suggest that it may pose risks, leading to regulatory reviews in various regions, including the European Union. As a result, some manufacturers are exploring alternatives to E171 in their products.
