UNAM Studies the Ayocote Bean as a Nutrient-Rich Functional Food
Researchers at the Universidad Nacional Autónoma de México (UNAM) are investigating the agricultural viability and nutritional profile of the ayocote, a large traditional legume native to central Mexico, according to findings detailed by investigators José Luis Sánchez Millán and Elsa Gutiérrez Cortez at the Facultad de Estudios Superiores (FES) Cuautitlán. Despite its deep historical roots in indigenous diets and high concentration of dietary fiber and antioxidants, the species remains commercially subutilized, prompting a structured evaluation of its water requirements, fertilization thresholds, and functional food applications.
- UNAM researchers are actively evaluating the agronomic requirements and nutritional composition of the ayocote (Phaseolus coccineus L.), a traditional Mexican legume known for its large size and dense nutrient profile.
- Laboratory findings indicate that the legume contains significant levels of antioxidants, including phenols and antocianinas, alongside high dietary fiber and essential minerals, positioning it as a viable candidate for functional food development.
- Processing challenges remain a central hurdle, as thermal processing exceeding 180 degrees Celsius degrades key heat-sensitive micronutrients, driving the search for low-temperature food manufacturing alternatives.
Agronomic Evaluation and Production Variables
Known scientifically as Phaseolus coccineus L. and derived from the Nahuatl term ayecotli (meaning “fat beans”), the ayocote significantly outpaces the common bean in physical dimensions while maintaining structural similarities. According to data released by UNAM, current field investigations focus on determining optimal planting density, water requirements, and precise application doses for nitrogen, phosphorus, and potassium. Researchers are systematically comparing the agricultural performance of the purple ayocote variety against conventional commercial beans to establish yield metrics per hectare.
A primary agronomic objective involves assessing the crop’s drought resistance capabilities and exploring cultivation methods that reduce or entirely eliminate dependence on synthetic agrochemicals.
Nutritional Profiling and Antioxidant Mechanisms
Biochemical analyses conducted at FES Cuautitlán have identified substantial concentrations of bioactive compounds within the legume. Beyond macronutrients such as proteins and complex carbohydrates, the ayocote matrix harbors high levels of dietary fiber and essential minerals including potassium, calcium, magnesium, sodium, iron, zinc, manganese, and copper. Most notably, the analysis reveals significant pools of phenolic compounds and anthocyanins, which function as potent antioxidants capable of mitigating oxidative stress at the cellular level.
These properties highlight the potential of Phaseolus coccineus L. as a functional or nutraceútico food source.
Thermal Processing Challenges and Food Engineering
Translating raw nutritional value into stable commercial products presents distinct biochemical obstacles. While the legume can be milled into granular solids suitable for incorporation into staples like bread and tortillas, researchers have observed that traditional baking and frying temperatures exceeding 180 degrees Celsius accelerate the thermal degradation of vital micronutrients.
To preserve the integrity of these heat-sensitive compounds, UNAM specialists are currently mapping degradation thresholds to establish strict processing guidelines. Concurrently, the team is engineering third-generation snack prototypes—such as baked tostadas—that bypass high-temperature cooking methods.
As research advances toward practical integration, recovering traditional regional crops like the ayocote offers a scientifically grounded pathway to enrich modern diets while preserving agricultural biodiversity across central Mexico.
