Effects of pH on the ability of flavonoids to act as Pickering emulsion stabilizers

Cutaneous biocompatible rutin-loaded gelatin-based nanoparticles increase the SPF of the association of UVA and UVB filters

“…Samples denominated as B-NC (blank GNP without rutin), and R-NC (GNP loaded with rutin) had the gelatin solution pH (second desolvation step) adjusted to 11.0 with NaOH 0.1 M, since rutin solubility is favored in alkaline medium (Luo et al, 2012). This phenomenon contributed to the entrapment efficiency of rutin in R-NC of 51.8 ± 1.4% (Table 2), promoting a significant increase in bioactive compound concentration, while maintaining physical stability.…”

Subcritical Water Induced Complexation of Soy Protein and Rutin: Improved Interfacial Properties and Emulsion Stability

“…However, this disagreement that NSPI–rutin mixture emulsion showed smaller oil droplet size and greater physical stability compared to pure protein emulsion may be related to low amount of rutin additive in this study (Cui and others ). A lower rutin addition to protein emulsion was performed to avoid the misunderstanding of stability mechanism, since rutin had some surface activity and successfully acted as a Pickering stabilizer (Luo and others ).…”

“…To quantify rutin‐binding capacity of SPI, protein samples were centrifuged at 8000 g for 20 min to remove insoluble rutin, and then the supernatants (0.2 mL) were added to a screw‐capped bottle containing methanol (9.8 mL) and stirred at 25 °C for 1 h. High‐performance liquid chromatography (HPLC) quantitative analysis of rutin was performed according to the method of Luo and others (). Water solubility of rutin at different temperature was immediately measured after heating without cooling in an ice bath.…”

“…To more effectively retard lipid oxidation, exogenous polyphenolic antioxidants, especially natural hydrophobic polyphenols (for example, rutin), are expected to incorporate into protein emulsions due to their safety and potent antioxidant properties, as well as self‐adsorption at the oil–water interface (Atarés and others ; Luo and others ; Cui and others ). Moreover, in view of interfacial occurrence of lipid oxidation, targeted polyphenol accumulation at the oil droplets’ surface is also expected to promote antioxidant effectiveness (Waraho and others 2013).Unfortunately, the poor solubility of polyphenols in hydrophilic and lipophilic medium limits its application in the field of functional foods as an antioxidant, especially in the emulsified systems, due partly to the unpredictable physical location and lower interface activity.…”

Mineralization and drug release of hydroxyapatite/poly( l -lactic acid) nanocomposite scaffolds prepared by Pickering emulsion templating

“…The fabrication procedure involves first preparing a Pickering emulsion and then solidifying the emulsion continuous phase. Pickering emulsion is a solid particle-stabilized emulsion [26][27][28][29][30][31][32], where solid particles are nearly irreversibly adsorbed at liquid-liquid interfaces and act as a barrier against coalescence making the resulted emulsions extremely stable [33][34][35][36]. Thus, Pickering emulsion templates are stable enough to maintain the designed porous structures in the fabrication procedure.…”
