Pearl Millet gains Acceptance as Wheat Alternative
Updated June 13, 2025
as drought conditions increasingly threaten wheat crops, American researchers are exploring pearl millet as a resilient, gluten-free alternative. A recent study indicates that U.S. consumers may readily accept pearl millet,a grain cultivated for centuries in arid regions of Africa and India,in place of some wheat flour.
The key, researchers found, lies in taste. Teams from Drexel University, the University of Pennsylvania, city University of New york, Brooklyn college and the Monell Chemical Senses Centre collaborated on sensory perception studies to gauge consumer acceptance of whole-grain pearl millet.
published in the journal Foods, the study revealed that fermented pearl millet flour can replace up to 20% of whole wheat flour in sandwich bread without negatively affecting consumer acceptance or purchase intent. Beyond that threshold, though, flavor acceptability declined, underscoring the importance of balancing nutrition with taste.
“This study highlights that simple food preparation methods, such as fermentation, can enhance the nutritional value of millet without compromising flavor — up to a point,” said May M. Cheung, assistant professor at City University of New York, Brooklyn College.
Pearl millet bran contains phytic acid, which can hinder the absorption of micronutrients. The researchers employed fermentation, a traditional and accessible technique, to reduce phytic acid levels while aligning with consumer preferences for minimally processed foods.
In initial tests, flatbreads made solely from pearl millet fermented for varying durations were evaluated. Longer fermentation proved more effective at reducing phytic acid, but also diminished taste appeal.Subsequent tests involved substituting fermented pearl millet for wheat flour in sandwich bread, ranging from 0% to 50%. Participants rated the bread samples based on taste and purchase intent. The team discovered that up to 20% fermented pearl millet flour could be incorporated before consumer rejection occurred.
“This kind of interdisciplinary research, while familiar in food science, is relatively new in culinary science. Where food scientists often go to the chemistry of food to solve a problem, culinary scientists look to the food’s flavors and traditional foodways to solve a similar problem,” said Jonathan Deutsch, professor and director of the Drexel Food Lab in the College of Nursing and Health Professions.
The findings hold meaningful implications for food manufacturing and public health.Millet, a drought-resistant and nutrient-rich grain, remains underutilized in the U.S. food supply. By identifying a method to enhance millet’s nutritional profile while preserving flavor, this research offers a practical approach to boosting its appeal. It also emphasizes the value of simple, natural food preparation techniques applicable to other nutrient-dense grains.
“I was surprised by how effectively simple practices inspired by traditional knowledge can improve nutrition without requiring a deep understanding of the underlying science,” cheung said.
Cheung also noted the surprising tolerance for up to 20% fermented millet flour substitution. ”Perhaps an even higher percentage of fermented millet can be added if we tested these samples in a population that is more familiar with fermented foods,” she added.
What’s next
Ongoing collaboration aims to further refine the balance between nutrition and sensory properties in millet food formulations,seeking the “sweet spot” where health benefits and consumer acceptance are maximized.
