For aging purposes, the mix was cooled (4.5 °C) and refrigerated
(4 °C) for 24 h. After aging, the aeration process was
performed by a batch freezer (−5±0.5 °C). Then, the ice
creams were packed in 120 ml plastic cups and stored
(−30 °C, 24 h) for hardening followed by keeping in a freezer
(−22 °C) prior to analysis (Marshall et al. 2003).
