3.5 Ice crystal size analysisValues of ice crystal equivalent diameter at 50% of the cumulative distribution (X50) andslope at these X50 valueswere used to characterize ice crystal size distributions (Table 4).There were no significant differences in these values before heat shock (P>0.05),whichshowed that the presence of stabilizers in ice cream had no direct effect on ice crystaldistribution after hardening, as has been reported by other studies (Miller-Livney andTable 3 The effect of type and concentration of stabilizers on colloidal properties of ice cream mix and icecreamFormulation Fat globule size (d4,3) mix Fat globule/aggregate size (d4,3) ice creamNo stabilizer 0.82±0.11c 1.37±0.47c0.1% BSG 23.6±5.71b 6.37±2.09b0.1% CMC/guar 0.69±0.053c 1.10±0.26c0.2% BSG 53.7±7.79a 22.49±3.76a0.2% CMC/guar 0.73±0.092c 1.18±0.13cDifferent letters in a column represent significant differences, P<0.05, n=3BSG basil seed gum, CMC carboxymethyl cellulose280 M. BahramParvar, H.D. GoffHartel 1997; Sutton andWilcox 1998; Flores andGoff 1999b; Regand and Goff 2002).Regand and Goff (2002) related this finding to the fact that stabilizers have no influenceon the initial freezing properties of an ice cream mix.
