Spray dried protein-polyphenol particles were produced using aqueous polyphenol extracts of rosemary (RM) or muscadine grape pomace (MG) complexed with insect protein (IP) alone or blended with pea protein 50:50 (IPP). The spray drying process was evaluated (solids recovery SR and polyphenol retention PR) and the four experimental protein-polyphenol treatments IP–RM, IP-MG, IPP–RM and IPP–MG were characterized regarding their physicochemical, bioactivity, functional, bioaccessibility and thermal stability properties. Higher SR (53.7-53.3%) and PR (53.1 – 62.5%) were observed for IPP-derived particles (p<0.05). Particles had water activity in the microbiologically stable range (0.24-0.32) and high protein content (29.5%-38.3%) All particles had low hygroscopicity (<15%) and solubility between 44-52.83%. Remarkably high phenolic content (>68.5 mg GAE/g) was shown for MG-derived particles. Good emulsifying activity (1.85 to 16.46 m2/g) and emulsifying stability (> 60%), foaming capacity (4 – 57%) and foaming stability (2.0-37.3%) were observed for all insect protein-polyphenol particles. Differently from MG-derived particles, RM-derived treatments showed higher polyphenol bioaccessibility than non-complexed polyphenols (p<0.05). Overall, our study demonstrates that spray drying microencapsulation is an efficient strategy to produce attractively colored, value-added functional protein-polyphenol ingredients using insect protein.}, journal={FUTURE FOODS}, author={Silva, Edilene Souza da and Xiong, Jia and Medeiros, Fabio Gonsalves Macedo de and Grace, Mary and Moncada, Marvin and Lila, Mary Ann and Hoskin, Roberta Targino}, year={2024}, month={Jun} }

It has been extensively studied for its antioxidant, antidepressant, and anti-inflammatory properties, and has recently gained new interest for use in high-end cosmetics. The present work aims to elucidate the skin-protective properties of saffron in human dermal fibroblasts. The skin-protective properties of saffron extract were evaluated in terms of tyrosinase and collagenase inhibition activities, antioxidant activity in mouse macrophage cells, collagen synthesis and hyaluronic acid synthesis and cell migration activity in primary dermal fibroblast normal human neonatal cells (HDFn). Saffron’s main phytoactive constituents - crocins, picrocrocin, safranal, and crocetin - were quantified by LC-MS at 91.0, 61.5, 3.6, and 1.9 mg/g, respectively. Saffron extract inhibited tyrosinase and collagenase with IC50 0.78 mg/mL and 0.1 mg/mL, respectively. Saffron extracts (100–200 μg/mg) suppressed reactive oxygen species and nitric oxide generation in lipopolysaccharide-stimulated RAW 264.7 murine macrophage cells and promoted collagen and hyaluronic acid synthesis in HDFn. Saffron extract at 25 μg/mg significantly promoted migration of HDFn cells (wound healing capacity) compared to control (no treatment). The findings highlighted the potential benefits of saffron extract relevant to skin resilience.}, journal={JOURNAL OF HERBAL MEDICINE}, author={Xiong, Jia and Grace, Mary H. and Kobayashi, Hideka and Lila, Mary Ann}, year={2023}, month={Feb} }

Four experimental groups were evaluated (BK–BC: blackcurrant pomace extract with buckwheat protein; CP–BC: blackcurrant pomace extract with chia:pea protein blend; BK–CC: cocoa extract with buckwheat protein; and CP–CC: cocoa extract with chia:pea protein blend) to determine physicochemical attributes, phytochemical content, antioxidant activity, and polyphenol in vitro bioaccessibility. Nonconventional, underexploited protein sources such as chia/pea protein blend and buckwheat protein efficiently produced functional microparticles with attractive color and texture, low hygroscopicity (<20% increase in moisture content when exposed to 86% relative humidity for 1 week), solubility above 50% at pH 7 and 10, and uniform particle size (29 < D4,3 < 56 µm). Besides this, the protein–polyphenol microparticles concentrated and protected health‐relevant polyphenol content. Anthocyanins were detected in blackcurrant treatments (around 20 mg cyanidin‐3‐O‐glucoside equivalents/g), while proanthocyanidins (PAC) were the most prevalent polyphenols in cocoa treatments (>100 mg PAC B2/g). Monomers were the main class of PAC in both BK–CC and CP–CC treatments. All protein–polyphenol treatments reduced both reactive oxygen species and nitric oxide production in lipopolysaccharide‐activated cells (p < 0.05). The polyphenol recovery index was high (>70%) for both oral and gastric phases, and BK‐derived groups had better bioaccessibility index compared to BC or CC alone (noncomplexed). This research provided a framework for delivery of high‐value ingredients to attend to an emerging market centered on protein‐rich, clean label plant‐based food products.}, journal={JOURNAL OF FOOD SCIENCE}, author={Hoskin, Roberta Targino and Grace, Mary H.

Because human health benefits are contingent on bioavailability after ingestion, the fate of these molecules during transit in the gastrointestinal tract (GIT) will dictate their utility as functional food ingredients. This brief review explores diverse applications of protein-polyphenol particles in the food industry and the bioaccessibility of both bioactive polyphenolic compounds and edible proteins. Evidence to date suggests that complexation of phytoactive polyphenolics effectively enhances their health-relevant impacts, specifically because the phytoactives are protected in the protein matrix during transit in the GIT, allowing intact, non-degraded molecules to reach the colon for catabolism at the gut microbiome level, a prerequisite to realize the health benefits of these active compounds.}, journal={JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY}, publisher={American Chemical Society (ACS)}, author={Lila, Mary Ann and Hoskin, Roberta Targino and Grace, Mary H. and Xiong, Jia and Strauch, Renee and Ferruzzi, Mario and Iorizzo, Massimo and Kay, Colin}, year={2022}, month={Apr} }

In this sense, BRs are a promising tool for promoting skin regeneration.Therefore, the objective of the present work was to analyze the effect of BRs in wound repair, mainly the inflammatory and proliferative phases, and their influence on migratory abilities in human dermal fibroblasts (HDFa), and consequently understand the mitochondrial metabolism.We measured nine natural and synthetic BRs for the inflammatory response in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. We further evaluated the migration activity in HDFa modeling promotion of wound closure after BRs exposure. In addition, we evaluated the 84 gene profiles linked to wound healing response using RT2 Profiler PCR Array and examined cellular bioenergetics using an extracellular flux analyzer.Results showed that LPS-induced cells had around 10 % lower reactive oxygen species and nitric oxide accumulation when treated with some BRs compounds. HDFa treated with homobrassinolide-based and homocastasterone-based compounds resulted in the greatest migratory activity and presents the best results for mitochondrial responses.Together, these results provided strong evidence for BRs' ability to promote skin health, particularly through contributions to both reducing excessive oxidative stress and controlling the inflammation process resulting in the best HDFa cell migration through the control of mitochondrial function.}, journal={LIFE SCIENCES}, author={Xiong, Jia and Bonney, Sierra and Goncalves, Reggiani Vilela and Esposito, Debora}, year={2022}, month={Oct} }

The post-processing retention of carnosic acid (CA), carnosol (CR) and rosmarinic acid (RA), their bioaccessibility, in vitro antioxidant activity, and storage stability were investigated in protein-rosemary particles compared to rosemary extract (RME). Solids recovery was highest for whey protein or whey-inulin blend complexed with rosemary (R–WPI, R–WIN, ~90%), followed by soy protein or soy-inulin (R–SPI, R–SIN, 60% and 70%); all were higher than rosemary alone (RME, 52%).

In vitro digestibility showed that whey protein isolate increased the bioaccessibility of CA and CR, with no effect on RA, which was highly bioaccessible in all formulations. The rosemary-protein-treatments retained high antioxidant activity measured by ROS and NO assays. CR and CA were particularly stable during 20 weeks of storage in protein-rosemary particles, and stayed at their higher concentration compared to RME.

Multiple studies in blueberry and other crops indicated that flavonoids and phenolic acids function as bioactive compounds in the human body promoting multiple health effects. Despite their importance, information is limited about the levels of variation in bioactive compounds within and between ploidy level and species, and their association with fruit quality traits. Such information is crucial to define a strategy to study the genetic mechanisms controlling these traits and to select for these traits in blueberry breeding programs. Here we evaluated 33 health related phytochemicals belonging to four major groups of flavonoids and phenolic acids across 128 blueberry accessions over two years together with fruit quality traits, including fruit weight, titratable acidity, total soluble acids and pH. Highly significant variation between accessions, years, and accession by year interaction were identified for most of the traits. Cluster analysis grouped phytochemicals by their functional structure (e.g., anthocyanins, flavanols, flavonols, and phenolic acids). Multivariate analysis of the traits resulted in separation of diploid, tetraploid and hexaploid accessions. Broad sense heritability of the traits estimated in 100 tetraploid accessions, ranged from 20 to 90%, with most traits revealing moderate to high broad sense heritability (H2 > 40%), suggesting that strong genetic factors control these traits. Fruit size can be estimated as a proxy of fruit weight or volume and vice versa, and it was negatively correlated with content of most of phytochemicals evaluated here. However, size-independent variation for anthocyanin content and profile (e.g., acylated vs. non-acylated anthocyanin) exists in the tetraploid accessions and can be explored to identify other factors such as genes related to the biosynthetic pathway that control this trait. This result also suggests that metabolite concentrations and fruit size, to a certain degree can be improved simultaneously in breeding programs. Overall, the results of this study provide a framework to uncover the genetic basis of bioactive compounds and fruit quality traits and will be useful to advance blueberry-breeding programs focusing on integrating these traits.}, journal={Frontiers in Plant Science}, author={Mengist, M.F. and Grace, M.H. and Xiong, J. and Kay, C.D. and Bassil, N. and Hummer, K. and Ferruzzi, M.G. and Lila, M.A. and Iorizzo, M.}, year={2020}, month={Apr} }

To evaluate a steroidal glycoalkaloid isolated from Easter lily bulbs for its potential wound healing promoting properties. A lily-derived steroidal glycoalkaloid (LSGA), (22R, 25R)-spirosol-5-en-3β-yl O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→4)-β-D-glucopyranoside, was isolated from Easter lily bulbs, and its structure was confirmed by LC-MS and NMR spectrometry. LSGA effects on wound scratch closure were evaluated in a primary human dermal fibroblast cell culture, and the changes in gene expression profiles were quantitated using an 84 wound-related gene qPCR microarray. LSGA promoted migration of dermal fibroblasts into the wounded area. The treatment was associated with a rapid upregulation of early inflammatory (CD40LG, CXCL11, IFNG, IL10, IL2 and IL4), cell growth (CSF3 and TNF) and remodeling (CTSG, F13A1, FGA, MMP and PLG) genes both in the wounded and unwounded cells treated with LSGA. A selective decrease in gene expression profiles associated with inflammatory (CXCL2 and CCL7) and remodeling (MMP7 and PLAT) phases was observed in wounded cells treated with LSGA, in contrast to the wounded cells (control). This study demonstrates that a glycoalkaloid present in lilies promoted fibroblast migration in vitro and affected inflammatory, remodeling and growth factor gene expression. The decreases in expression of key genes may impact the wound healing process, possibly contributing to an earlier end of the inflammatory response and shortening the early phases of model tissue reconstitution.

Standard calibration curves were linear for all analytes with correlation coefficients >0.99. The relative standard deviation for intra- and inter-day precision was lower than 10%. The method allowed an easy and selective identification and quantification of phenolics in blueberries with divergent profiles. The in vitro antioxidant assay results were strongly correlated with total phenolics and total anthocyanin content. Lowbush blueberry extracts (50 μg/mL) reduced ROS and NO production, and inhibited the transcription of the proinflammatory cytokines IL-6β, COX2, iNOS, and IL-6 in the in vitro assays at much lower concentrations than pink fruited berries (250 μg/mL).}, journal={Food Chemistry}, publisher={Elsevier BV}, author={Grace, Mary H. and Xiong, Jia and Esposito, Debora and Ehlenfeldt, Mark and Lila, Mary Ann}, year={2019}, month={Mar}, pages={336–346} }

Subsequently, the changes in the total polyphenol content (TPC) and biological activity were studied. The results showed that the phenolic compounds from A. mearnsii remained stable, and TPC underwent few changes during gastric digestion. Nonetheless, intestinal digestion led to the degradation of proanthocyanidins (PAs) and a significant decrease in TPC (26%). Degradation was determined by normal-phase HPLC and gel permeation chromatography. Only monomers, dimers, and trimers of flavan-3-ols were identified in the serum-accessible fraction for characterization of their bioaccessibility. The results also indicated the obvious antioxidant capacity of PAs from A. mearnsii bark, and ~53% of the α-glucosidase–inhibitory effect was preserved. All these findings show that PAs from A. mearnsii bark as a native plant source may be particularly beneficial for human health as a natural nutritional supplement.}, number={7}, journal={Molecules}, publisher={MDPI AG}, author={Chen, Xiao and Xiong, Jia and He, Lingxiao and Zhang, Yu and Li, Xun and Zhang, Liping and Wang, Fei}, year={2018}, month={Jul}, pages={1804} }

Fractions B4, B5, B6, B7 (total phenolics 850.3, 983.0, 843.9, and 572.5 mg·g−1, respectively; proanthocyanidins 75.7, 90.5, 95.0, and 44.8 mg·g−1, respectively) showed significant activities against reactive oxygen species (ROS), nitric oxide (NO) production, and expression of pro-inflammatory genes interleukin-1β (IL-1β) and inducible nitric oxide synthase (iNOS) in a lipopolysaccharide (LPS)-stimulated mouse macrophage cell line RAW 264.7. All the extracts suppressed α-glucosidase and α-amylase activities, two primary enzymes responsible for carbohydrate digestion. A. mearnsii bark samples possessed significantly stronger inhibitory effects against α-glucosidase enzyme (IC50 of 0.4−1.4 μg·mL−1) than the pharmaceutical acarbose (IC50 141.8 μg·mL−1). B6 and B7 (IC50 17.6 and 11.7 μg·mL−1, respectively) exhibited α-amylase inhibitory activity as efficacious as acarbose (IC50 15.4 μg·mL−1).
