About
GPC – Grain Processing Company is a plant built from scratch for one job: milling corn. The line, the laboratory and the logistics all work around a single raw material, so our product parameters stay constant from batch to batch.
One raw material, full specialisation
We are part of a group that works with farmers from sowing onwards. POLMAIS selects the varieties and advises in the field, the purchasing and drying business takes in the harvest, and GPC turns it into food ingredients. We know the corn before it reaches the mill.
We mill only vitreous flint corn. Its hard, round kernel gives grits with an even granulation and a deep yellow colour.
