Determination of freezing point
For this purpose, one part (volumetric) of ice cream mix was
diluted by three parts (volumetric) of water and its freezing point
was measured using Cryostar (Funke Gerber Gmbh, Berlin,
Germany) (Ohmes et al. 1998; Saeedabadian et al. 2008).
Viscosity measurement
The ice cream mixes (aged for 24 h at 4 °C) were poured in
a 500 ml container and their apparent viscosity were determined
using a Visco Elite rotational viscometer (Fungilab
S/A, Barcelona, Spain) equipped with spindle No L1 at
ambient (20±0.5 °C) temperature (Marshall et al. 2003).
