Therefore, the required maximum force was used for
comparing the stickiness of various treated samples
(Matak 1999). Moreover, all samples were conditioned
(−22 °C, 24 h) before conducting the tests.
Melting rate
Fifty grams of cylindrical blocks of conditioned ice creams
(−22 °C, 24 h) were placed on sieve (Mesh No 6, Aperture
3.35 mm, USA Standard Testing Sieve) which was mounted
on electric balance at 24±0.5 °C. The weight of melted ice
cream was recorded every 5 min and the total amount of
melted ice cream (during 30 min) was used as per cent for
comparison purposes (Baer et al. 1999).
Overrun
The per cent of overrun was calculated as follows (Marshall
et al. 2003).
