Cryogenic grinding of frozen herbs uses liquid nitrogen to produce a fine, aroma‑rich powder while preserving volatile compounds.
Origin: Japanese and French (Modern culinary techniques) — Japan, France
See full technique reference →The sub‑−150 °C environment halts enzymatic oxidation and preserves terpenoid aromatics. Mechanical shear at cryogenic temperatures fractures cell walls, releasing essential oils without generating heat that would degrade heat‑sensitive compounds. The process also reduces polyphenol oxidase activity, maintaining color and antioxidant capacity.
Primary Reaction
Inhibition of polyphenol oxidase activity and mechanical disruption of cell walls
