Nature-identical colourings are ingredients that are completely identical to those that are found in nature. These colourings have been produced synthetically since the 1950s for reasons of economy. For example, extraction of riboflavin from milk is much too cost-intensive.
It would also be impossible to use carrots to meet the huge demand for beta carotene required by the world market because the necessary quantities are simply not available.
Today, beta carotene and beta-Apo-8’ carotenal as well as Lycopin are the only nature-identical colourings that are of any economic importance.
