Organic (natural) food colorings are coloring substances, extracted by physical methods of plant and animal sources. Sometimes they are subjected to chemical modification to improve the technology and consumer properties. Several food colorings are produced not only by extracting them from natural raw materials, but also synthetically.
Today, for coloring foods natural food colorings are offered like curcumin or turmeric (E100), carmine (E120), chlorophyll (E140), annatto (E160v), beta-carotene (E160a), red beet dye beatnik (E162) and other natural coloring substances.
For example, beta-carotene extracted from carrots, by its chemical structure complies with beta-carotene, obtained by microbiological or chemical way (the natural beta-carotene are significantly more expensive and therefore rarely used in food industry as a coloring).
