Rheological (G' at zone I and slope of zone II), tribological (mean friction coefficient of boundary regime and slope of the mixed regime) and textural properties (hardness and scooping energy) of ice creams with different polysaccharides. The notation of the samples includes the name of the polysaccharide and the concentration used. For example, LBG055 refers to a sample with 0.55% LBG.
Ice cream | G' at zone I (106 Pa, G'ZI) | Slope of zone II (SZII) | Mean friction coefficient of boundary regime (FCB) | Slope of the mixed regime (SMR) | Hardness (MPa) | Scooping energy (N · mm) |
