PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
Rapidly freezes fruit purées to –196 °C using liquid nitrogen, producing sub‑10 µm ice crystals that preserve texture and color.
Origin: Molecular gastronomy pioneers (21st century) — Global
See full technique reference →The extreme temperature drop causes water in the puree to crystallize almost instantaneously, limiting ice crystal growth to less than 10 µm. This minimizes cell rupture and preserves the smooth mouthfeel. Additionally, the rapid temperature change inactivates polyphenol oxidase, preventing enzymatic browning.
Primary Reaction
Rapid freezing of water to ice (H₂O(l) → H₂O(s)) with minimal crystal growth; thermal denaturation of polyphenol oxidase (PPO)
