Curcumin loaded and protective system based on complex of κ-carrageenan and lysozyme

Curcumin encapsulated in the complex of lysozyme/carboxymethylcellulose and implications for the antioxidant activity of curcumin

“…On the other hand, the Ly-Cur-CMC coacervates still retained high antioxidative effectiveness at pH 7. The structure stability of Ly-Cur-CMC coacervates brings about a more proper microenvironment for the reaction of Cur with DPPH, which results were similar to other reports about the Cur protective system by proteins and polysaccharides Xu et al, 2014). It was noteworthy that the Ly-Cur-CMC coacervates, especially the Ly-Cur-CMC 1.2, exhibited better DPPH radical scavenging ability than free Cur and Ly-Cur.…”

“…It was reported that Cur has limited thermal and pH stability (Wang et al, 1997;Xu et al, 2014). For testing the stability of Cur encapsulated by Ly and CMC, the free Cur, Ly-Cur and Ly-Cur-CMC were prepared at pH 6 and pH 7 before and after food pasteurization (60°C, 30 min).…”

Supramolecular design of coordination bonding architecture on zein nanoparticles for pH-responsive anticancer drug delivery

“…DOX in the percolated solutions was determined by a UV-vis spectrophotometer (UV-1100, MAPADA) at 480nm. The free DOX was obtained by calculating the DOX content that were ultracentrifuged at 4000 × g for 30 min in a refrigerated centrifuge (TGL-20000cR) with angle rotor through 10 kDa MWCO Amicon filter [27]. The encapsulation efficiency was defined as the drug content that was entrapped into zein-TA/metal NPs and calculated as follows:…”

Designing excipient emulsions to increase nutraceutical bioavailability: emulsifier type influences curcumin stability and bioaccessibility by altering gastrointestinal fate

“…4 The potential health benefits of curcumin, as well as its good safety profile, has led to interest in incorporating it into functional food products as a nutraceutical ingredient. One strategy for improving the functional performance of curcumin is to encapsulate it within food-grade delivery systems such as nanoparticles, [6][7][8][9] hydrogel beads, 10 biopolymer complexes, 11 emulsions, 12-15 colloidosomes 16 and amorphous solid suspensions. 4,5 The use of curcumin as a nutraceutical ingredient can be facilitated by developing strategies to improve its solubility, stability, and bioaccessibility.…”
