Using u(SFC-Chocolate,23_C) = 67% and u(SFC-ModelFilling,23_C) = 47% we obtain a BrTAG concentration of the liquid fat phase in the filling of 9.4% (SFC values were measured for equal samples according to the official AOCS Cd16b-93 method by using NMR, and obtained through personal communication with the Laboratory of Food Technology and Engineering, Ghent University, Belgium).
The ratio of the liquid fat phase in the filling relative to the liquid fat phase in the shell is very much in favour of the filling, as the fat content in the shell is low as well as the liquid fat fraction. Further, the liquid phase in the model filling is saturated by CB TAGs.
The average concentration of BrTAGs in the liquid fat phase at complete equilibrium between the liquid fat phase in the filling and the liquid fat phase in the shell will thus be 8.3% for the whole model praline, which would give 2.7% BrTAGs counted on the total fat phase in the shell.
