Organic flour, is obtained from the milling of traditional cereals such as wheat or alternatives such as barley, corn etc. cultivated with organic farming methods, but, to be sold as such, it must be certified. Even the cereal, to be considered organic, must contain the certifications of appropriate control bodies that verify the requirements of the farm that produced it. Every year, checks are made to ensure the maintenance of conditions of the certification. The cereal for the production of organic flour is grown without the help of synthetic chemicals (pesticides, herbicides, chemical fertilizers, pesticides and pest control) and can not be derived from genetically modified seeds. The milling of organic grain is carried in cylinders or stone.
