What You Need to Know
At temperatures between 150 °C and 260 °C, reducing sugars react with amino acids to form melanoidins, aldehydes, ketones and furans that generate brown color and complex aromas. Simultaneously, proteins unfold near 70 °C, allowing collagen to gelatinize or cross‑link, which determines juiciness and texture. Oil‑based techniques also render fats, contributing to crispness while influencing oil uptake.
