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

Soy protein isolate as a nanocarrier for enhanced water dispersibility, stability and bioaccessibility of β‐carotene

“…In addition to the stability, the complexation remarkably improved the bioaccessibility of curcumin . In another recent work, we further found that SPI exhibits a very high capacity to bind curcumin, with maximal loading amount reaching 103.9 µg mg −1 protein . Both the number and nature of hydrophobic sites for this protein are important for the nanoparticles in SPI to exhibit this high curcumin‐binding capacity .…”

“…In another recent work, we further found that SPI exhibits a very high capacity to bind curcumin, with maximal loading amount reaching 103.9 µg mg −1 protein . Both the number and nature of hydrophobic sites for this protein are important for the nanoparticles in SPI to exhibit this high curcumin‐binding capacity . Furthermore, it was reported that soy proteins (purified glycinin and β ‐conglycinin) also had a good affinity to vitamin B 12 (a water‐soluble vitamin) …”

“…Our recent work investigated the complexation of nanoparticles in unheated and heated (at 75–90°C) with curcumin, and indicated that the encapsulation efficiency of curcumin progressively decreased with increasing the initial curcumin concentration, while the loading amount linearly increased . In addition to the stability, the complexation remarkably improved the bioaccessibility of curcumin . In another recent work, we further found that SPI exhibits a very high capacity to bind curcumin, with maximal loading amount reaching 103.9 µg mg −1 protein .…”

“…Although the complexation between proteins and phenolic compounds, e.g. resveratrol, flavonoids and curcumin, has been well characterised, very few works are available addressing the complexation or interaction of proteins with carotenoids . β ‐Carotene is a lipid‐soluble carotenoid consisting of a polyene system with 11 conjugated double bonds and a β‐ring at each end of the chain.…”

Complexation of curcumin with whey protein isolate for enhancing its aqueous solubility through a solvent‐free pH‐driven approach

“…The complexation of proteins and curcumin has recently attracted a great deal of interest for improving the curcumin aqueous solubility and physico‐chemical stability. Various proteins have been used as carriers for curcumin delivery such as whey protein nanofibrils (Mohammadian et al, ), zein protein (Patel et al, ), and soy protein isolate (Chen, Li, & Tang, , ).…”
