Milk β-lactoglobulin complexes with tea polyphenols

Effect of removal of phenolic compounds on structural and thermal properties of sunflower protein isolate

“…Rawel et al (2002b) reported that upon interaction of chlorogenic acid with bovine serum albumin (BSA), there was a reduction in a helix with a parallel increase in remaining structures, indicating destructing effect on BSA. Contrary to these results Kanakis et al (2011) reported different results for b lactoglobulin upon interaction with polyphenols. They reported that in the presence of polyphenols, conformation of b lactoglobulin was changed with an increase in b-sheet and ahelix, suggesting stronger structural stabilization of proteins.…”

Preparation of arginine–glycine–aspartic acid-modified biopolymeric nanoparticles containing epigalloccatechin-3-gallate for targeting vascular endothelial cells to inhibit corneal neovascularization

“…After uptake, NPs can be shipped to primary endosomes and then transported to secondary endosomes, which then fuse with lysosomes. 40 Lysosomes are a strong digestion system, and are the key clearance mechanism of NP elimination. The ability of NPs to escape endolysosomes depends on the surface charge of the NPs.…”

Whey Protein Complexes with Green Tea Polyphenols: Antimicrobial, Osteoblast-Stimulatory, and Antioxidant Activities

“…However, the addition of WPI had a masking effect on GTE's scavenging activity, as demonstrated by a decrease in its percentage inhibition. Such an effect on protein-bound polyphenols is probably mediated by hydrogen bonds, which occur between the hydroxyl groups of the catechins and the protein [Kanakis et al, 2011]. A similar masking effect was observed for casein with green tea catechins by means of the Trolox equivalent antioxidant capacity (TEAC) test [Arts et al, 2001], and for bLG and EGCG complexes using the ferric-reducing ability of plasma (FRAP) test [Zorilla et al, 2011].…”
