The ice cream mixes were prepared in 2 kg batches. The
liquid milk was heated to 40–45 °C before being mixed with
the solid ingredients. All the required ingredients were then
thoroughly mixed with the milk. The mixes were pasteurised
at 85 °C for 15 min and dispersed with stirring for 5 min at
45 °C using a simple mixer (Model 6790; Tefal, Rumilly,
France).
