Colloidal approach to prepare colour blends from colourants with different solubility profiles

Nanocomplexation of soy protein isolate with curcumin: Influence of ultrasonic treatment

“…3 B, C). The observations of the influence on the ζ-potential are distinctly contrasting from the previous observations for the influence of complexation with curcumin on the ζ-potential of SPI at a much higher c value (5.0%, w/v) and a relatively low [cur] (Chen et al, 2015), and of zein particles at acidic pH values (Patel, Heussen, Dorst, Hazekamp, & Velikov, 2013;Patel et al, 2010), where a reduction in magnitude of ζ-potential was observed after the complexation with curcumin. The remarkable decreases in H o are basically consistent with the observations of our previous work, though in the previous case, the magnitude of the decreases was much less (Chen et al, 2015).…”

“…6 A). Similar kinetics of degradation for free curcumin at around room temperature have been observed in the literature (Chen et al, 2015;Patel et al, 2013;Wang et al, 1997;Yang et al, 2013). The degradation rate of curcumin was remarkably slowed down by the nanocomplexation with either non-or ultrasonic-treated SPI, especially during the initial storage, e.g.…”

Core–shell biopolymer nanoparticle delivery systems: Synthesis and characterization of curcumin fortified zein–pectin nanoparticles

“…This property makes zein a suitable material for development of colloidal delivery systems to encapsulate hydrophobic bioactive molecules, such as curcumin (Chen & Zhong, 2014;Patel et al, 2010Patel et al, , 2013Zhong & Jin, 2009). However, zein particles often have poor stability to aggregation when exposed to environmental conditions commonly encountered in food and pharmaceutical products, such as certain pH ranges, high salt contents, and (Patel et al, 2010).…”

Enhancement of curcumin water dispersibility and antioxidant activity using core–shell protein–polysaccharide nanoparticles

“…More than 50% of the amino acids in zein are hydrophobic, which makes it one of the few natural proteins that can be readily solubilized in aqueous ethanol solutions (60-90%) but not in water (Dong, Padua, & Wang, 2013;Zhang, Luo, & Wang, 2011). This property makes zein a suitable material for development of nanoparticle delivery systems to encapsulate lipophilic curcumin molecules (Patel, Heussen, Dorst, Hazekamp, & Velikov, 2013). However, zein nanoparticles have poor aggregation stability when exposed to certain environmental conditions, such as pH, salt, and temperature.…”
