Artificial food colors are added to foods for a number of reasons. First of all, they are to restore the original color of the food, which it has lost through processing. Sometimes it is also about changing the color of the product to be more attractive and eye-catching. Unfortunately, in some cases, dyes are used to hide product flaws.

  • gel dyes – they are very efficient and easy to use. The gel dyes can be diluted with water or alcohol.
  • powder dyes – they can be used both dry and wet. Powder dyes are used both to decorate baked goods and to refresh food colors.

Coloring markers, edible glitter and flake dyes are also available in stores. Online stores offer the largest selection of colors. Remember, however, that most ready-made food dyes contain substances that are harmful to health. Therefore, it is worth preparing dyes using home methods.

Synthetic food dyes – are they harmful to our health?

Synthetic food dyes are a diverse group of chemical compounds (azo, indigoide, xanthene or trialylmethane). It is worth knowing that artificial dyes are harmful, especially for children – they can cause behavior changes, problems with concentration, anxiety and hyperactivity. Below you will find a list of the most harmful dyes. Unfortunately, their use is allowed in the countries of the European Union:

What products are the above dyes added to? We find them mainly in sweetened drinks, jellies, puddings, chewing gums, sweet dragées, lollipops, jelly beans, ice cream. Unfortunately, these are products that we often give to children – remember that they are the ones most exposed to the adverse effects of food dyes. Before we decide to buy a specific product, it is worth reading its composition carefully.
