Food dyes, also known as artificial food colors, are chemically produced additives used to enhance the appearance of various food and beverage products.

These synthetic colors are formulated in laboratories and added to countless items on supermarket shelves, ranging from candies and cereals to sodas and snacks. They come in a rainbow of shades, transforming plain-looking products into visually appealing treats.

Artificial food coloring is typically derived from petroleum, a non-renewable resource. The base components are chemically altered to create different shades.

For example, Red 40 is made from petroleum distillates, while Yellow 5 and Yellow 6 are derived from coal tar. These chemical formulations are then mixed with other substances to produce the desired colors.

It’s important to note that natural food dyes derived from plants and minerals are also available as alternatives.
