At the University of Missouri, researchers are delving into the intriguing complexities of Maiz Morado—a striking variety of purple corn hailing from South America.
This unique corn not only stands out for its rich hues but also possesses a treasure trove of nutritional benefits that extend far beyond what is typically offered by conventional yellow varieties found in American diets, which range from fresh cobs to breakfast cereals.
Research Focus and Goals
Led by Assistant Professor Pavel Somavat, the team is investigating multiple strains of corn, including shades of blue, red, and purple, in a concerted effort to uncover their potential health advantages.
Collaborating with Sherry Flint-Garcia, a geneticist with the U.S. Department of Agriculture’s Agricultural Research Service, the researchers have spent the last three years cultivating colored corn variants, meticulously documenting their findings in the journal Industrial Crops and Products.
The primary goal of this initiative is twofold: to pinpoint the most promising corn varieties while simultaneously facilitating Flint-Garcia’s breeding cycles.
The researchers are not only evaluating the genetic makeup of these colorful corns but are also examining their adaptability to the temperamental climates of the Midwest.
A paramount focus of their work is to enhance the economic value of these crops, presenting new opportunities for farmers in Missouri, a major corn-producing state in the United States.
Nutritional Benefits and Applications
Among the varieties studied, Maiz Morado emerges as a noteworthy contender.
Its dark purple kernels boast antioxidant levels that surpass those found in blueberries, alongside a robust profile of flavonoids, phenolic acids, and tannins.
These attributes position Maiz Morado as a frontrunner for innovative food applications that could disrupt standard dietary practices.
Yet despite its promising properties, Maiz Morado faces climatic hurdles in Missouri, prompting the necessity for hybridization with yellow corn to create adaptable breeding lines.
This strategic approach aims to cultivate full-sized purple corn ears capable of thriving in commercial settings, which would enable farmers to tap into burgeoning markets and diversify their income streams.
Although people’s acceptance of purple corn may take time to grow, the nutritional advantages could still find their way into the food supply in myriad ways.
One avenue being explored is the use of natural food dyes derived from this colorful corn.
These extracts could replace synthetic colorants like Red Dye 40, a popular but controversial ingredient linked to health concerns and legislative efforts to ban synthetic dyes in certain contexts, such as in school meals.
By utilizing natural pigments, the food industry could not only bolster the safety and nutritional profiles of various products but also enhance consumer trust.
Innovative Applications and Sustainability
Additionally, the research team is investigating the extraction of plant proteins and phytochemicals from what is typically considered waste biomass of purple corn.
This innovative pursuit could lead to the creation of biodegradable and edible packaging materials imbued with antimicrobial properties, offering a sustainable alternative to conventional plastics that plague the environment.
Further compounding the potential of purple corn, the team is examining its intrinsic pest-repellent qualities.
Preliminary findings suggest that the phytochemicals present in these colorful corn types may offer organic farming and greenhouse cultivation a natural deterrent against pests, particularly benefiting high-value fruits and vegetables.
The research encapsulates a broader vision for the reimagining of corn’s role in agriculture and consumer products, extending its relevance far beyond mere carbohydrates.
By tapping into the remarkable health benefits and diverse applications of non-yellow corn, there lies an opportunity not only to enrich dietary options but also to inspire lasting change within the agricultural landscape.
For those interested in diving deeper into this groundbreaking research, the findings are featured in a recent publication titled “Evaluation of dry milling characteristics and polyphenolic contents of fourteen conventionally bred colored corn varieties for value-added coproducts recovery” in Industrial Crops and Products.
