<p>Egg white was known for its excellent foaming properties, and some reports had studied the effect of polyphenol such as green tea on the foaming properties. However, ovalbumin, as the most abundant component of egg white protein, few literatures have reported the effects of polyphenols on its structure and foam property. In this study, ferulic acid (FA) was selected to explore the influence of polyphenol on the structure and foaming properties of ovalbumin (OVA). Results showed that hydrophobic interaction and hydrogen chemical bonds were the main driving force. FA could induce a significant decrease of free-SH content (12.76-3.72 μmol/g), a slight decline of surface hydrophobicity (716.39-577.65). Meanwhile, combined with the results of fluorescence spectroscopy and circular dichroism spectroscopy, we conclude that FA changed the structures and molecular flexibility of OVA. The increase of particle size and absolute zeta-potential showed there was a little aggregation between OVA molecules, proved FA could act as a cross-linker between OVA proteins. This behavior makes the adjacent films more firm and stable, therefore improved the foaming properties. This study suggested that FA could be a potential foaming agent to modify the foaming properties of OVA in the foam-related food industry.In the present work, acetone, ethanol and water extracts of rowanberry (Sorbus aucuparia L.) pomace were evaluated for their antiproliferative, antimicrobial and antioxidative effects. Chemical composition of the extracts was determined by UPLC-ESI-MS/MS and spectrophotometric methods. Neochlorogenic and chlorogenic acids were the major phenolic compounds. The water extract contained the highest total proanthocyanidins content (301 ± 18.9 mg/g) and demonstrated the highest antioxidant activity in the all assays (DPPH, FRAP and ORAC). Extracts isolated from rowanberry pomace effectively inhibited the growth of undesirable microorganisms, especially Gram-positive bacteria. Acetone extract was the strongest antimicrobial agent followed by water and ethanol extracts. Acetone and water extracts demonstrated also higher cytotoxic potential in cell viability assays (SRB and MTT) using Caco-2 cells. In general, the results suggest that rowanberry pomace is a promising source of natural compounds with antioxidant and biological activities.Porphyra sp. is one of the most cultivated and commercially valuable species, recognized for its high protein content (up to 47% dry weight) and complete amino acids profile. Based on these characteristics, P. dioica produced in an integrated multitrophic aquaculture system was selected for this study.  <a href="https://www.selleckchem.com/products/epacadostat-incb024360.html">Epacadostat</a> The aim was to evaluate the effect of in vitro simulated gastrointestinal digestion (SGID) on the antioxidant activity of the hydrolysates generated from dried blades and from the protein isolate (PI) extracted from them. The alkali extraction and isoelectric precipitation (pH 4.5) of P. dioica protein prior SGID allowed isolating/enriching protein, while direct SGID of blades allowed assessing the potential influence of other constituents of the sample on the bioactive properties. Overall, SGID promoted the release of smaller bioactive peptides and their in vitro antioxidant activity, which was assessed by different methods (DPPH and ABTS+ scavenging capacity, ORAC and FRAP), was improved compared to the intact samples. Blades submitted to direct SGID presented significantly higher ORAC values compared to PI (2010 ± 136 vs 542 ± 21 µmol TE/g FDS, respectively). For the remaining assays, PI presented more potent antioxidant activity, especially FRAP (131 ± 2 vs 16 ± 1 µmol TE/g FDS) and ABTS+ (1244 ± 157 vs 230 ± 15 µmol TE/g FDS). The results indicated that gastrointestinal digestion improved the antioxidant activity of P. dioica-derived hydrolysates, as they presented effective activity against different oxidative mechanisms, thus suggesting health-protecting effects.Preservation of food through fermentation is an ancient practice that, besides extending produce shelf-life, has represented a significant source of nutrients and health-promoting compounds in the human diet throughout history. Traditional fermented beverages are an essential element of the cultural and culinary heritage of many countries. In Mexico, several indigenous fermented beverages have been consumed since prehispanic times, and are still used for ceremonial purposes. The production of these beverages is generally from fruits, plants, maize, and maize dough, which are utilized as a substrate by microorganisms during spontaneous fermentation. This review compiles information from the most relevant studies concerning Mexican fermented beverages. These have generally focused on three principal aspects (1) the identification and isolation of the endogenous microorganisms involved in the fermentation process, including the addition of specific molds, yeasts, and bacteria under controlled conditions aiming to standardize the fermentation process, (2) an exploration of the functionality of the microorganisms and the subproducts generated during their metabolic process, and (3) an analysis of the nutritional value of the fermented beverages. Hence, this review aims at contributing to the dissemination of biotechnological knowledge of Mexican fermented beverages, towards the identification and advancement of alternative research pathways.Inflammatory and innate immune responses triggered by pathogen-associated and other danger-associated signals emerging during infections, results in the activation of cytosolic inflammasomes. The nod-like receptor pyrin domain containing 3 (NLRP3) is one of the inflammasomes mediating such responses through the activation of caspase-1, which increases the production and release of pro-inflammatory cytokines, such as IL-1β and IL-18 and induces programmed cell death through pyroptosis. NLRP3 is thought to play a crucial role in the underlying inflammatory responses in many lifestyles related chronic diseases. Consequently, research on the NLRP3 inflammasome has expanded dramatically in recent years. Although several studies have investigated the role of NLRP3 activation in chronic kidney disease (CKD), few studies have evaluated strategies to modulate its activation by means of interventions using non-pharmacological strategies. This review discusses some nutritional strategies (bioactive compounds, probiotics and caloric restriction) that have been shown to influence NLRP3 in experimental models of renal disease, and in CKD.</p>
