3.5 Ice crystal size analysis
Values of ice crystal equivalent diameter at 50% of the cumulative distribution (X50) and
slope 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),which
showed that the presence of stabilizers in ice cream had no direct effect on ice crystal
distribution after hardening, as has been reported by other studies (Miller-Livney and
