A method of producing an extruded water-based frozen compositionhaving a high ice content, using a screw barrel extruder having a barrel provided with an inlet and an exit die, the method comprising: (a) feeding an unfrozen composition into the barrel of the extruder via the inlet thereof, the unfrozen composition comprising: (i)at least 85%, preferably at least 90% by weight of the water; and (ii) at least 0.5%, preferably at least 1%, more preferably at least 2% by weight of a balance consisting of one or more other ingredients. (b) freezing the unfrozen composition inside the barrel to form thefrozen composition; and (c) extruding the frozen composition through theexit dieof the extruder to form said water-based frozen product; wherein at least part of the barrel is cooled with a coolant at a first temperature sufficient to form the frozen composition, and preferably the exit die is cooled with a coolant at a temperature higher than the first temperature,such that the frozen composition is still frozen but extrudable. |
