Description
Controlled‑rate freezing of ice‑cream batter uses precise temperature ramps to control ice‑crystal nucleation and protein unfolding, producing a fine, stable micro‑structure.
Technical
During controlled‑rate freezing, water in the batter nucleates at a uniform rate, forming ice crystals that are small and evenly distributed. Casein micelles unfold and reorganize around these crystals, while fat globules are stabilized by the protein matrix, preventing coalescence. No net chemical reaction occurs; the process is governed by physical phase changes and protein–lipid interactions.
