Gruma, the world's largest maize flower producer with operations in the US, Europe and South America, has acquired Australian tortilla manufacturer Rositas Investments. The purchase of Rositas cost Gruma AUS$17.6m (US$13.26).

Rositas Investments, which markets tortillas under the Rositas brand, has registered average annual sales of approximately AUS$22m, the company said.

The purchase, South American reports suggest, is part of Gruma's recent strategy to expand its presence overseas. Plans are in place for Gruma to open a plant in China, Juan Gonzalez Moreno, president of the company's Asia-Oceania division told reporters.
