Sensory analyses
Six panelists were chosen for the assessment of the sensory attributes of the ice cream samples. Three 1-h sessions were conducted to train the panellists. Each sample was coded using a three-digit random number and served to the panelists in individually partitioned booths. Samples were portioned into 30 ml cups with covers. Softness was evaluated following the 9-point scale where 0 – coarse and 8 – soft. A different definition was used for flavour: 0 – strong off-flavour and 8 – natural flavour.
