Ardent Mills is expanding its specialty grain portfolio with a recent acquisition.

The company’s Annex by Ardent Mills division expects to finalize its purchase of Andean Naturals Inc.’s quinoa sourcing, cleaning and packaging operation in Yuba City, California, in mid-February.

Yuba City will be Ardent Mills’ first gluten-free sourcing and cleaning facility with the ability to expand to additional grains.

“Our industry is rapidly changing as consumers’ appetite for variety in their diets continues to increase,” says Dan Dye, CEO of Ardent Mills. “As a result, we are making proactive investments in The Annex to meet consumer demand for high-quality, nutritious grains and other sources of plant-based ingredients. With this acquisition, we will be able to offer a complete solution for quinoa and other gluten-free ingredients.”

As part of the deal, Andean Naturals’ president and founder, Sergio Nunez de Arco, will join Ardent Mills.
