What You Need to Know
Nixtamalization of corn in a calcium hydroxide solution de‑esterifies hemicellulose, reduces phytic acid, and improves niacin bioavailability, while the high‑sugar quince paste undergoes pectin gelation at 95 °C. The starch retrogrades slowly at serving temperature (~60 °C), stabilizing the texture, and the pH of 2.5‑3.5 is essential for optimal pectin network formation.
