Coloration is a special labeling of crops that is carried out for the purpose of subsequent identification of cereals intended for sowing, as well as as animal feed.

This marking allows you to identify the crop and its purpose without the need for special equipment.

Such requirements apply to products exported to a number of countries - such as Saudi Arabia, Jordan, Tunisia and Iran.

The coloration procedure is carried out by staining with harmless food dyes, which are certified by the Ministry of Health of Ukraine as well as relevant authorities of importing country.

The following colorants are among the permitted dyes:

  • Yellow S / Sunset (color - yellow), E 110;
  • Karmazin (color - red), E 122;
  • Green S (color - green), E 142.

The essence of the procedure is that the dye is sprayed on the surface of the grains in the form of a watery solution. During subsequent processing, the coloring substance can one easily removed from the grain.

Marking is usually carried out in port when loading cargo onto ships, and is often combined with grain fumigation.

During dyeing, it is fundamentally important to control that the grain is evenly colored, and the amount of dye does not exceed the calculated norms.
