Wheat germ oil is obtained by first cold pressing of the germ of the grains of the botanical species Triticum vulgare L. belonging to the Poaceae family.
It is an alohexaploid plant, due to its conformation of 42 chromosomes divided into 6 sets from three different ones. The plant has three identical genomes, which have repeated genetic information, which gives the species itself great adaptability to different environments.
Wheat is a cereal that is grown almost all over the world, from the limits of the Arctic to near the Equator and in all kinds of latitudes, from sea level to more than 4,000 m. It is adaptable to diverse conditions and thrives in sub-tropical, moderately temperate and moderately cold climates. The shape of the seed is ovoid and the embryo or germ is housed in the most flattened extremity.
