Which Lime Is Used in Tortilla & Nixtamalization Process?

Nixtamalization is the ancient Mesoamerican technique that transforms dried corn into soft, flavorful, nutrient-rich dough used for tortillas, tacos, tamales, nachos, and corn chips.
The key ingredient in this process is food-grade hydrated lime, also known as:

  • Calcium Hydroxide (Ca(OH)₂)

  • Food-Grade Lime

  • Pickling Lime

  • Khaane Wala Chuna (Food Grade)

This lime is added to hot water, releasing the alkaline reaction needed to soften corn and increase its nutritional value.

Keywords included: tortilla lime, nixtamal lime, food-grade lime for corn, masa lime, lime for corn soaking, Ca(OH)₂ tortillas, authentic tortilla process.

Which Lime Is Used in Tortilla & Nixtamalization?

The lime used is:

Food-Grade Hydrated Lime (Calcium Hydroxide – Ca(OH)₂)

This is the only safe and approved lime for:

  • Nixtamalization

  • Tortilla dough (masa)

  • Corn chips

  • Tamales

  • Arepas

  • Nachos

  • Masa harina (corn flour)

Hydrated lime must be food-safe, not industrial grade.

Why Food-Grade Hydrated Lime Is Used

  1. Softens dried corn kernels
  2. Helps remove the outer hull
  3. Enhances natural aroma
  4. Improves corn digestibility
  5. Increases niacin availability
  6. Boosts nutritional value
  7. Helps form smooth masa dough
  8. Gives tortillas authentic flavor and elasticity

How Lime Works in the Nixtamalization Process

  1. Dried corn is boiled in water with food-grade hydrated lime.
  2. Alkali breaks down the hull (pericarp).
  3. Corn softens and absorbs nutrients better.
  4. Husk separates easily during washing.
  5. Softened kernels are ground into masa.
  6. Masa becomes tortillas, chips, tamales, etc.

This process has been used for over 3,000 years.
