Nixtamalization Effects on Aflatoxin and Metabolites in Guatemalan Maize

Guatemalan maize was used in a controlled lab study to evaluate local nixtamalization practices. The dataset likely contains measurements of aflatoxin B1 concentration reduction, mineral content changes, and untargeted metabolomics results from nine processing conditions. Hannah Glesener authored this dataset, which was last updated on April 23, 2026.

Use Cases

• Model aflatoxin reduction efficacy based on calcium hydroxide concentration and steeping duration parameters
• Analyze changes in mineral content (calcium, iron, copper, magnesium) resulting from alkaline cooking
• Identify processing-associated chemical changes for future targeted metabolomics analysis

Strengths

• Reports a specific 81% average reduction in aflatoxin B1 concentration across all tested conditions
• Documents a substantial 808.22% increase in calcium content as a result of processing

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
