GIMSA began its operations in 1949 in Cerralvo, Nuevo Leon, with the inauguration of the world's first plant manufacturing "nixtamal
" corn flour , marking  Gruma's start with an installed capacity of 15 tons of flour per month.

In the beginning,  our nascent industry's process was quite rudimentary, but we improved the processes and devoted years to research and effort to improve the  machines' operations and the quality of the flour, and it was through this innovative process that the name and most important brand of "nixtamal"corn flour in Mexico was born: Maseca.

Over six decades, GIMSA has developed an efficient infrastructure for the industrialization and sale of our corn-flour-dough-tortilla chain nationwide.  Our operations in Mexico are carried out mainly through two subsidiaries: Grupo Industrial Maseca (GIMSA) and Molinera de Mexico (Molinera).

The legacy of our business, which has prospered over the last 60 years, is GIMSA, Mexico's leading  corn flour producer. MASECA, our major corn flour brand has great recognitionandis the most popular of all our brands around the world.
