“…As listed in Table 2, the opacity of FG-0.5C, FG-1.0C, and FG-2.0C is 0.925, 0.866, and 0.821 mm −1 , respectively. The decrease was the result of carvacrol droplets distributed throughout the FG matrix to promote light scattering [33,34]. Sonication significantly (p < 0.05) reduced the film opacity owing to the decrease in the size of carvacrol droplets in the FG-C film-forming solutions, and the rough surface of non-sonication FG-C films decreased the opacity for the light scattering effect.…”

Carvacrol is a natural compound known to be a highly effective antibacterial; however, it is a hydrophobic molecule, which is a limitation to its use within food packaging. Flaxseed gum (FG) films containing different contents of carvacrol (C) were produced by a film-casting method with sonication. The effects of sonication power and time on the properties of the FG-C films were investigated by measuring the film thickness, mechanical properties, contact angle, opacity, water vapor permeability (WVP), water sorption isotherm, Fourier transform infrared spectroscopy(FTIR), differential scanning calorimetry (DSC), antibacterial and antioxidant activities, and microstructure. The results showed that sonication power and time had significant effects on mechanical and barrier properties, film opacity, and degradability (p < 0.05). The tensile strength (TS) and elongation at break (EB) values exhibited an obvious improvement after sonication, and FG-0.5C-6030 had the lowest TS (33.40 MPa) and EB (4.46%) values. FG-C films formed a denser structure and the contact angle was improved as a result of sonication, which improved the integration of carvacrol into the FG matrix. In terms of microstructure, sonication resulted in a homogeneous and continuous crosssection of FG-C films, and regular surface and cross-sectional images were obtained through the highest acoustic intensity and longest time treatment. The FG films incorporated with carvacrol displayed antibacterial properties against Staphylococcus aureus, Vibrio parahaemolyticus, Shewanella putrefaciens, and Pseudomonas fluorescens, as well as increased antioxidant properties, and sonication was proven to enhance both of them.

“…Although both formulations had a particle size of less than 500 nm (and therefore suitable for intestinal absorption), SLN-G, which was characterized by a mean diameter of about 250 nm, showed the best dimensional properties for the absorption by intestinal cells. However, the PDI was around 0.7, indicating that the particles were in a state of polydispersity distribution [50]. This is probably because, in aqueous solvents, G may undergo solubilization or dispersion with consequent formation of vesicles, micelles or microscopic globules [51] that could lead to the presence of multiple nanoparticle populations.…”

Solid Lipid Nanoparticles as Formulative Strategy to Increase Oral Permeation of a Molecule Active in Multidrug-Resistant Tuberculosis Management

The role of mycobacterial efflux pumps in drug-resistant tuberculosis has been widely reported. Recently, a new compound, named SS13, has been synthesized, and its activity as a potential efflux inhibitor has been demonstrated. In this work, the chemical–physical properties of the SS13 were investigated; furthermore, a formulative study aimed to develop a formulation suitable for oral administration was performed. SS13 shows nonintrinsic antitubercular activity, but it increases the antitubercular activity of all the tested drugs on several strains. SS13 is insoluble in different simulated gastrointestinal media; thus, its oral absorption could be limited. Solid lipid nanoparticles (SLNs) were, therefore, developed by using two different lipids, Witepsol and/or Gelucire. Nanoparticles, having a particle size (range of 200–450 nm with regards to the formulation composition) suitable for intestinal absorption, are able to load SS13 and to improve its permeation through the intestinal mucosa compared to the pure compound. The cytotoxicity is influenced by the concentration of nanoparticles administered. These promising results support the potential application of these nanocarriers for increasing the oral permeation of SS13 in multidrug-resistant tuberculosis management.

“…This method was employed also for a whipped cream system, with the aim of monitoring its microstructural evolution during aeration (as shown in Figure 2) (Han et al, 2018). The same approach can be extended to complex double emulsions systems, as presented in Xiao et al, 2017and Estrada-Fernández et al, 2018. Further applications of CSLM in the characterization of food materials includes elucidating the lipid organization in milk fat globule membranes (MFGMs) (Lopez et al, 2015).…”
