Figure 5: Rheological profile of the alternative emulsions and samples 1 (top) and 2 (bottom)
The parameters obtained from the textural analysis in all prepared sample emulsions are presented in Table 9. The alternative that comes closer to the textural parameters of Sample 1 is K1-R3. For Sample 2, both formulations (L2-R3-V1 and K2-R3-V1) have similar values when compared to Sample 2. Although no sensorial tests were performed on these formulations, it has been reported that the textural parameters here evaluated do correlate well with the sensorial attributes of the final product. In particular, firmness is related to the tackiness as perceived by the user, and consistency, cohesiveness, and index of viscosity all directly correlate with slipperiness.48
