## 4 Conclusions  
In this work, oil-in-water nanoemulgels formulated with lemon essential oil and low methoxyl citrus peel pectin have been developed using a preparation method based on the preparation of a nanoemulsion and a pectin gel separately and then mixing them. The stirring time and rotational rate during the mixing step do not influence either the particle size distribution or the values of the mean diameters, pointing out that the mixing process does not affect the droplet properties of the starting nanoemulsion. Note that these processing variables do not significantly influence the global destabilization parameter TSI either. However, from the results obtained, 3 min and 200 rpm were set due to these conditions exhibiting the lowest TSI values. Different pectin gel/nanoemulsion mass ratios were exhibited at 1 day of aging with very similar DTP, according to the fact \begin{table}

Figure 9: Variation of TSI with aging time as a function of the pectin gel/emulsion mass ratio for emulgels formulated with lemon essential oil. that all the emulgels contained the same nanoemulsion. However, with aging time, an aggregation process occurred, especially of the micro or nanoparticles of pectin. These particles were present as the pectin gel was really a sheared pectin gel as a result of its method of preparation. This process was more pronounced with higher pectin content. All samples showed a shear thinning flow behavior and exhibited an increase in viscosity with aging, the greater the higher the initial pectin content. This result was consistent with the aggregation process mentioned above. To conclude, the emulgel containing the higher pectin gel/nanoemulsion ratio presented the longest physical stability. This study brings to light the role played by microgels formed during the preparation of the structured phase in the stability of emulgels formulated with lemon essential oil and low methoxyl pectin. Further tests should be carried out to check if the results obtained here hold for any pectin gel concentration and CaCl\({}_{2}\)/ pectin mass ratio. Furthermore, it is worth exploring different methods of emulgel preparation not only at a lab-scale. Additionally, micrographs obtained by confocal laser and electron microscopy would provide valuable information on the microstructure of these emulgels formed from a matrix of sheared gel.
