Nixtamalisation: Technique of Maize Fortification

In News

  • Recently, a study has thrown light on how Maya people fortified their maize with the chemical process known as ‘nixtamalisation’.

Nixtamalisation Method

  • Nixtamalisation is a method by which the ancient peoples of Mesoamerica like the Maya used to soak and cook their maize in an alkaline solution and make it more palatable, nutritious and non-toxic.
  • The process ensures that the maize contains amino acids, calcium and Vitamin B2, which can be utilised by the human body.
  • It also eliminates certain mycotoxins present in maize.
