Maize (Corn)

Maize is a high-yield grain that can be eaten fresh or dried for long storage. It is widely used for porridge, breads, and animal feed.

Description of what it is like

Large kernels attached to a central cob. Kernels harden when dried and can be ground into coarse meal or fine flour.

Origin and where to find it

• Environments: Warm, sunny fields with moderate rainfall.
• Signs: Tall stalks with broad leaves and ears wrapped in husks.
• It is a cultivated crop grown in rows or intercropped.

Minimum processing required

• Drying: Ears are dried to reduce moisture.
• Shelling: Kernels are removed from the cob.
• Grinding: Kernels are milled into meal.
• Optional alkaline cooking: Improves nutrition and digestibility with Lime.

Tools needed to work on it

• Simple shelling by hand or with tools.
• Mortar for pounding.
• Hand Mill for meal and flour.
• Containers for storage.
• Fire for cooking.

Common forms of use

• Boiled or roasted ears.
• Ground meal for porridge or flatbreads.
• Fermented doughs and drinks.

Possible substitutes

• Wheat or Rice as alternative grains.
• Potato or Cassava as starchy roots.

Limitations and common failures

• Nutrient gaps: Without alkaline cooking, niacin availability is low.
• Storage pests: Insects and rodents damage stored kernels.
• Moisture loss: Damp grain spoils quickly.

Risks and safety

• Mold: Poorly dried grain can develop toxins.
• Fire risk: Milling dust is flammable in enclosed spaces.
