Out of 12 predicted binders, delphinidin-3-glucoside, cyanidin-3-glucoside, procyanidin C1, and chlorogenic acid were further evaluated in vitro. Circular dichroism, UV-Vis spectroscopy, and immunoblotting determined their capacity to (i) bind to Ara h 2, (ii) induce protein secondary structural changes, and (iii) inhibit IgE binding epitopes. UV-Vis spectroscopy clearly indicated that procyanidin C1 and chlorogenic acid interacted with Ara h 2, and circular dichroism results suggested that interactions with these polyphenols resulted in changes to Ara h 2 secondary structures. Immunoblotting showed that procyanidin C1 and chlorogenic acid bound to Ara h 2 significantly decreased the IgE binding capacity by 37% and 50%, respectively. These results suggest that certain polyphenols can inhibit IgE recognition of Ara h 2 by obstructing linear IgE epitopes.}, journal={FOOD CHEMISTRY}, author={Plundrich, Nathalie J. and Cook, Bethany T. and Maleki, Soheila J. and Fourches, Denis and Lila, Mary Ann}, year={2019}, month={Jun}, pages={287–295} }

The aim of this study was to assess the capacity of peanut proteins complexed to polyphenol extracts to reduce allergic response in C3H/HeJ mice. Mice were sensitized to peanut flour followed by exposure to amino acid diets fortified with peanut protein-polyphenol aggregates of either with low (15%; w/w) or high (40%; w/w) complexation ratios of blueberry (BB-Low and BB-High) and cranberry (CB-Low and CB-High) extracts. Treatment groups on diets with high complexation ratios of blueberry and cranberry aggregates showed significant reduction in peanut specific plasma Immunoglobulin E (IgE). Western blot analysis of spleen lysates showed CD63 protein expression was reduced in a dose-dependent manner in blueberry and cranberry complexed peanut protein supplemented diet groups. Our results demonstrate for the first time that complexation of polyphenols to peanut flour can potentially lower plasma IgE of peanut-sensitized C3H/HeJ mice.}, journal={FOOD CHEMISTRY}, author={Bansode, Rishipal R. and Randolph, Priscilla D. and Plundrich, Nathalie J. and Lila, Mary Ann and Williams, Leonard L.}, year={2019}, month={Nov} }

There is a desire to increase consumption of proteins and polyphenols based on health considerations, and one approach is to form protein-polyphenol particles that combine both health and structural functionality in food products. The roles of proteins and polyphenols individually, or when bound together, are discussed in terms of health benefits (nutrition, disease prevention, satiety, allergy alleviation) and impact on food structure. The overall goal should be a rational design of protein-polyphenol particles to ensure a positive contribution to food quality, protein nutrition, and delivery of a health-relevant dose of polyphenols to the gastrointestinal tract.}, journal={FOOD HYDROCOLLOIDS}, author={Foegeding, E.

We previously reported a method to leach and concentrate quinoa bioactives into a complex phytochemical mixture termed quinoa leachate ( QL ). Here, we aimed to determine the effect of QL and its chemically distinct fractions on five biochemical endpoints relevant to skin care applications: (i) cell viability, (ii) matrix metalloproteinase ( MMP ) m RNA expression, (iii) MMP enzymatic activity, (iv) tyrosinase enzymatic activity and (v) intracellular reactive oxygen species ( ROS ) production. Methods Quinoa leachate was fractionated and chemically characterized using column chromatography and liquid chromatography–mass spectrometry ( LC ‐ MS ). Cell viability was determined using a MTT assay in four mammalian cell lines. MMP ‐1 m RNA expression was assessed in human dermal fibroblasts ( HDF ) via q RT ‐ PCR . The enzymatic activity of MMP ‐9 and tyrosinase was measured using fluorometric and colorimetric in vitro assays, respectively. Lipopolysaccharide ( LPS )‐induced ROS production was determined in human dermal fibroblasts by fluorescence intensity of an oxidant‐sensitive probe. Results Quinoa leachate was separated into three fractions: (i) carbohydrate‐rich fraction ( QL ‐ C ; 71.3% w/w of QL ); (ii) phytoecdysone, polyphenol and protein‐rich fraction ( QL ‐ P , 13.3% w/w of QL ); (iii) oil‐rich fraction ( QL ‐ O , 10.8% w/w of QL ). QL did not reduce cell viability in any of the four cell lines tested. QL , QL ‐ P and QL ‐ O each significantly inhibited MMP ‐1 m RNA expression in HDF at a concentration of 5 μg mL −1 . QL and QL ‐ P also significantly inhibited MMP ‐9 enzymatic activity, whereas QL ‐ P demonstrated significant tyrosinase enzymatic inhibition. Furthermore, QL , QL ‐ P , QL ‐ O and 20 HE significantly inhibited intracellular ROS production. Conclusion This study is the first to demonstrate the MMP , tyrosinase and ROS inhibiting properties of multiple different phytochemical components derived from quinoa seeds. Our work indicates that quinoa phytochemicals may play a role in the treatment and prevention of skin ageing through a multiplicity of effects.}, number={2}, journal={INTERNATIONAL JOURNAL OF COSMETIC SCIENCE}, author={Graf, B.

In this study, the stability of hypoallergenic peanut protein-polyphenol complexes was evaluated during simulated in vitro gastric digestion. When digested with pepsin, the basic subunit of the peanut allergen Ara h 3 was more rapidly hydrolyzed in peanut protein-cranberry or green tea polyphenol complexes compared to uncomplexed peanut flour. Ara h 2 was also hydrolyzed more quickly in the peanut protein-cranberry polyphenol complex than in uncomplexed peanut flour. Peptides from peanut protein-cranberry polyphenol complexes and peanut protein-green tea polyphenol complexes were substantially less immunoreactive (based on their capacity to bind to peanut-specific IgE from patient plasma) compared to peptides from uncomplexed peanut flour. These results suggest that peanut protein-polyphenol complexes may be less immunoreactive passing through the digestive tract in vivo, contributing to their attenuated allergenicity.}, number={7}, journal={FOOD & FUNCTION}, author={Plundrich, Nathalie J. and White, Brittany L. and Dean, Lisa L. and Davis, Jack P. and Foegeding, E.

Upon peanut consumption by an allergic individual, epitopes on peanut proteins bind and cross-link peanut-specific IgE on mast cell and basophil surfaces triggering the cells to release inflammatory mediators responsible for allergic reactions. Polyphenolic phytochemicals have high affinity to bind proteins and form soluble and insoluble complexes with unique functionality. This study investigated the allergenicity of polyphenol-fortified peanut matrices prepared by complexing various polyphenol-rich plant juices and extracts with peanut flour. Polyphenol-fortified peanut matrices reduced IgE binding to one or more peanut allergens (Ara h 1, Ara h 2, Ara h 3, and Ara h 6). Attenuated total reflectance−Fourier transform infrared spectroscopy (ATR-FTIR) suggested changes in secondary protein structure. Peanut protein–cranberry polyphenol fortified matrices triggered significantly less basophil degranulation than unmodified flour in an ex vivo assay using human blood and less mast cell degranulation when used to orally challenge peanut-allergic mice. Polyphenol fortification of peanut flour resulted in a hypoallergenic matrix with reduced IgE binding and degranulation capacity, likely due to changes in protein secondary structure or masking of epitopes, suggesting potential applications for oral immunotherapy.}, number={29}, journal={JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY}, author={Plundrich, Nathalie J. and Kulis, Mike and White, Brittany L. and Grace, Mary H. and Guo, Rishu and Burks, A.

Methods In this study, an efficient tactic is demonstrated for concentrating and stabilizing skin‐beneficial bioactive compounds from muscadine grape and blackcurrant juice or muscadine pomace, into hemp flour ( HF ), hemp protein isolate ( HPI ) and soy protein isolate ( SPI ) matrices suitable for cosmetic applications. Results Anthocyanins were most efficiently captured from blackcurrant juice into HF (8.39 mg g −1 ). HPI most effectively captured total phenolics from muscadine pomace (72.32 and 77.32 mg g −1 from Noble and Carlos, respectively), while the three matrices incorporated highest levels of ellagic acid, gallic acid, and PAC B1 from Noble muscadine grape juice. The enriched matrices demonstrated effective in vitro inhibition of tyrosinase (up to 57.29% for blackcurrant juice‐ HPI matrix), and in general, juice sources provided greater inhibition on L‐dopamine oxidation by tyrosinase than pomace sources. The polyphenol‐enriched matrices effectively inhibited microbial proliferation in a screening assay against S taphylococcus aureus bacteria, whereas untreated HF , HPI or SPI did not inhibit bacterial growth.

Depending on DSF concentration and juice dilution, the concentration of blueberry anthocyanins and total polyphenols sorbed to DSF ranged from 2–22 mg/g and 10–95 mg/g, respectively while the concentration of anthocyanins and proanthocyanidins in cranberry polyphenol-enriched DSF ranged from 2.5–17 mg/g and 21–101 mg/g, respectively. Blueberry polyphenols present in one serving of fresh blueberries (73 g) were delivered in just 1.4 g of blueberry polyphenol-enriched DSF. Similarly, one gram of cranberry polyphenol-enriched DSF delivered the amount of proanthocyanidins available in three 240 ml servings of cranberry juice cocktail. The concentration of blueberry anthocyanins and total polyphenols eluted from DSF remained constant after 22 weeks of incubation at 37 °C, demonstrating the high stability of the polyphenol–DSF matrix. LC–MS analysis of eluates confirmed that DSF retained major cranberry and blueberry polyphenols intact. Blueberry polyphenol-enriched DSF exhibited significant hypoglycaemic activities in C57bl/6J mice, and cranberry polyphenol-enriched DSF showed antimicrobial and anti-UTI activities in vitro, confirming its efficacy.
