Description
Nixtamalization is an alkaline hydrolysis process that leaches phytates and cyanogenic compounds while converting bound proteins into more digestible forms.
Technical
The process uses a 1–2 % calcium hydroxide solution heated to 90–100 °C for 12–18 hours, followed by steeping in the same solution for 12–24 hours. Calcium hydroxide hydrolyzes hemicellulose and liberates free niacin, increasing its bioavailability by up to 30 %. The alkaline environment also denatures proteins, converting them into soluble peptides that improve digestibility.
