Laser‑etched micro‑grooves on protein surfaces increase surface area and trigger localized Maillard reactions, boosting aroma release without bulk heating.
Origin: Japanese (2020s) — Japan
See full technique reference →The 1064 nm Nd:YAG laser creates 20‑50 µm micro‑grooves that raise surface area by ~30 %. Localized temperature spikes of 250‑350 °C for 5‑20 ms induce surface‑only Maillard chemistry, forming melanoidins, pyrazines, furans, and aldehydes that enhance flavor. Precise control of fluence, power, and scan speed is essential to avoid charring, protein cracking, and moisture loss.
