Azteca Millings take pride in our expertise, which has been enhanced by our 1996 strategic association between the agro-industrial giant Archer Daniels Midland and our parent company, Gruma Corporation. Additionally, Gruma has more than 37 registered patents for the production of corn masa flour and the production of corn and flour tortillas. Gruma's milling operation functions internationally through three large divisions; Mexico with 20 plants, Central and South America with 8 plants, and the United States with 5 plants.
