Volodkevich Bite Jaws probe imitates the force of biting the biscuit (Fig. 8). All the formulations except B40 showed a typical penetration curve with a maximum corresponding to the
point when the probe penetrated the sample following of a decrease in force values, indicating relaxation of the stress, and finally, the force rose again as the increasing dimensions of the probe penetrated the sample. In fact, no significant differences (P>0.05) in force values of B0, B10, and B20 were found (Table 4). B30 showed a significant increase (P
