Natural food coloring mainly comes from plants, animals, or minerals. Common food coloring includes beet red (extracted from beets), carotene (from carrots), and curcumin (extracted from turmeric). Because they come from natural sources and have only undergone simple physical processing, these food colorings are often considered safer choices.

Artificial synthetic food coloring is a chemical substance, that is produced in the laboratory through chemical synthesis. Common synthetic food coloring includes carmine (E120), lemon yellow (E102), bright blue (E133), indigo (E132), cochineal worm red (E124), etc. This kind of food coloring usually has brighter colors, stronger stability, and lower costs. Due to the aforementioned factors, this food coloring is widely used in the food industry. However, its safety has always been controversial.

The use of food coloring

The addition of food coloring can enhance food’s color. Brightly colored foods are more likely to attract consumers' attention and enhance their appetite, therefore that can enhance their desire to purchase. For example, foods like candy and jelly often add food coloring to enhance the overall visual effect.

Restore color loss during processing. During food’s processing and storage, color may change due to high temperature, light, or other factors. The food will inevitably lose its original color to a certain extent. The addition of food coloring can restore or enhance color. That can maintain color stability and consistency, and restore or maintain food’s original color.

Some artificial food coloring exhibit carcinogenic risks in animal experiments, such as sodium nitrite and certain synthetic dyes. Although these results have not been confirmed in the human body, they still raise public concerns about artificial colors. The safety of food coloring mainly depends on its source, dosage, and individual sensitivity. Some artificial food coloring may cause allergic reactions, such as skin rashes, itching, and difficulty breathing. Children and people who are allergic to certain substances are an especially special group that may have risk after having food coloring. Food safety regulatory agencies in various countries have different regulations and standards for the use of food coloring. Relevant institutions have detailed regulations on the types and maximum usage of food coloring to ensure their safe use.

To ensure the safety of food coloring, consumers should pay more attention to the following aspects. When purchasing food, it is important to carefully check the product label and understand the type and content of food coloring that is used. Try to choose products that are indicated to use natural coloring. Try to minimize the intake of foods that have a large amount of artificial colors, especially for children and sensitive people.
