“…The content of total polyphenolics in the dry extract with the addition of 20 % MD (340.1 mg GAE/g) was slightly lower compared to the dry extract without carriers (342.6 mg GAE/g). The superior encapsulation efficiency of WP (92.02 %) compared to MD (75.80 %) can be partly explained by the possibility of complexation between phenolic compounds and WP molecules (de Morais et al, 2020). These results show that WP carrier effectively encloses the extract ingredients into powder particles and thus preserves sensitive phenolic compounds.…”

Willowherb (Epilobium angustifolium L.) leaves are a valuable source of polyphenolic compounds (phenolic acids, flavonoids, and ellagitannins) that are mainly used in the treatment of benign prostatic hyperplasia. In the presented study, the impacts of maltodextrin and whey protein as carriers on the efficiency of spray drying and physicochemical properties of the obtained powders were examined. The use of carriers significantly improved the drying yield (over 60 %). Moisture content, hygroscopicity, and rehydration time of all dried extracts (without the carrier, with maltodextrin and whey protein) were at an acceptable level, while their flowability and cohesiveness were poor. The encapsulation efficiency of polyphenols in a whey protein carrier of 92.02 % was significantly higher compared to 75.80 % for maltodextrin. These results show that whey protein efficiently encloses the extract ingredients into powder particles and thus preserves sensitive phenolic compounds during the drying process. The efficacy of flavonoid encapsulation was also high (93.00 % for maltodextrin and 94.34 % for whey protein), with no statistically significant differences between carrier types. Therefore, willowherb leaves extract can be successfully encapsulated by spray drying using maltodextrin and whey protein as carriers.

“…TP have been reported to act as antioxidants by donation of hydrogen atoms, acceptance of free radicals, interruption of chain oxidation reactions or by chelating metals (Gime ´nez et al, 2013). When TP were incorporated into protein based coating solutions, the two compounds may interact by hydrophobic interaction and hydrogen bonding between the carbonyl group of protein-peptide bond and the phenolic hydroxyl group of polyphenols (Thongkaew et al, 2014;de Morais et al, 2020), thus, the properties of each other may be changed. Interactions between polyphenols and whey protein decreased the antioxidant and antimicrobial performance of Argentinean green tea (Jakobek, 2015;Kanakis et al, 2011;Staszewski et al, 2011).…”

Effects of tea polyphenols (TP) incorporation on physicochemical and antioxidative properties of whey protein isolate (WPI) coating were studied. Two WPI coating solutions were prepared by heating WPI solutions (pH 8, 90 °C) for 30 min and then TP was incorporated. TP addition could increase the negative zeta potential of 5% solution. The surface hydrophobicity index of both solutions was increased and intrinsic fluorescence intensity decreased greatly after addition of TP. 2,2-Diphenyl-1picrylhydrazyl (DPPH) and 2,2 0 -azinobis (2 ethylbenzothiazoline-6-sulfonate) (ABTS) radical scavenging capacities of both solutions increased with increasing TP. Compared with apple pieces coated with whey protein only, those with TP containing whey protein coatings showed lower browning index and slight changes in weight loss during 24 h storage. Data indicated that TP could influence the physicochemical properties and improve the antioxidant activity of WPI coating solutions and can be used to retard the enzymatic browning of fruit during storage.

“…The results proved that the addition of LSPC significantly improved the chemical stability of the nanoemulsion, and the use of whey protein enhanced the antioxidant activity of LSPC. Morais has reported on the interactions of whey protein with (−)-EGCG and caffeic acid (CA) at different pH values and the antioxidant capacities of the complexes [ 206 ]. The study showed that the complexation of the two polyphenols with whey protein altered the protein structure under both acidic and neutral conditions, and the effect of CA was more significant.…”

Nanoformulations to Enhance the Bioavailability and Physiological Functions of Polyphenols

Polyphenols are micronutrients that are widely present in human daily diets. Numerous studies have demonstrated their potential as antioxidants and anti-inflammatory agents, and for cancer prevention, heart protection and the treatment of neurodegenerative diseases. However, due to their vulnerability to environmental conditions and low bioavailability, their application in the food and medical fields is greatly limited. Nanoformulations, as excellent drug delivery systems, can overcome these limitations and maximize the pharmacological effects of polyphenols. In this review, we summarize the biological activities of polyphenols, together with systems for their delivery, including phospholipid complexes, lipid-based nanoparticles, protein-based nanoparticles, niosomes, polymers, micelles, emulsions and metal nanoparticles. The application of polyphenol nanoparticles in food and medicine is also discussed. Although loading into nanoparticles solves the main limitation to application of polyphenolic compounds, there are some concerns about their toxicological safety after entry into the human body. It is therefore necessary to conduct toxicity studies and residue analysis on the carrier.
