Red iron oxide

Red iron oxide is a food ingredient that gives a bright red colour to various products. It is a synthetic compound, which means it is made in a lab rather than extracted from natural sources like plants or animals. This red pigment is commonly used in the food industry to enhance the visual appeal of foods.

To make red iron oxide, scientists combine iron with oxygen in specific ways to create the vibrant red pigment. This process ensures that the colouring is safe for consumption and meets strict quality standards. Once produced, it is added to various food products to give them a red hue.

You might spot red iron oxide on food labels because it is used to improve the appearance of certain items. For example, it can be found in red-coloured candies, sauces, and baked goods. This ingredient plays a crucial role in making these foods visually appealing without affecting their taste or texture.
