The DDGS (Dried Distillers Grains with Solubles) is the coproduct resulting from the production of bioethanol by means of the conversion through fermentation of the starch in cereals into bioethanol and the ulterior extraction of the latter through distillation.

It is a source of vegetal protein, energy, fiber and vitamins used in animal feed. This feed use implies that DGS is subject to strict quality controls to guarantee both its nutritional properties and those derived from the application of the legislation on food safety in force.
