What You Need to Know
Nixtamalization, an alkaline hydrolysis of corn in limewater, liberates bound calcium and produces soluble peptides that improve nutrient bioavailability and create a distinct flavor profile. During baking, the Maillard reaction between reducing sugars and amino acids develops the golden crust and complex aromas, while starch gelatinization at ~70–80 °C gives the tortilla its soft texture.
