Maximum force at breakage

Of several physical parameters derived from the force-deformation curve (three-point bending assay) only the relation of the maximum force at breakage (MFB) of the dried products with water activity will be discussed here (Figure 7.7). At low moisture content, air dried samples showed a lower MFB than the FD sample. This may be because during drying in hot air.
